Ampeel: Appearance: Dull green back, light-tan underside, turquoise eyes, and a tooth-filled mouth

Body: Made up of a head, eight body segments, and a tail segment.

Electrical Prongs: Each segment has multiple brown-red/green prongs with glowing white tips that produce bright cyan electrical arcs.

Electricity: It uses water to complete a natural electrical circuit, allowing it to generate powerful electric shocks.

Behavior: Normally swims passively, occasionally changing direction. When threatened or approached, it becomes aggressive and surrounds itself with an electrical barrier before biting or shocking its attacker.

Combat: Its electricity can seriously damage a Seamoth and can also damage Prawn Suits and, to a lesser extent, Cyclops submarines.

Defense: The Seamoth's Perimeter Defense System is ineffective against it. Stasis Rifles, Repulsion Cannons, and Torpedoes are more useful.

When attacked: It retaliates with a bite or electric shock, then usually flees.

Respawning: Ampeels do not respawn after being killed.

Biter -

Appearance: Bright red upper body with a pale grayish-blue underside.

Head: Two turquoise eyes, nostril-like structures, a small mouth filled with razor-sharp teeth, and five black horizontal stripes.

Fins: Has dorsal and caudal fins but no pectoral fins.

Special Organ: A small forehead growth functions as an advanced olfactory organ, allowing it to detect blood and bodily fluids and track prey.

Intelligence: The PDA states that about 2% of its body is brain, unusually high compared with Earth fish.

Behavior: Extremely fast and territorial. It makes quiet growls and clicks and will attack creatures that get too close.

Attack: Each bite deals 7 damage to the player.

Feeding: Biters will eat corpses—even other Biters—and can temporarily be distracted by fish offered by the player.

Groups: Usually found in small groups of 2–3, but larger swarms can become very dangerous.

Vehicles: They can also attack the Seamoth, producing a noticeable tapping sound.

Blighter -

Appearance: Similar body shape to a Biter, but with a more decayed appearance.

Eyes: Dark-brown sclera with milky-white pupils, giving it a zombified appearance.

Coloration: Golden-brown on top with a pale white underside.

Front Protrusion: Has a short structure that produces a dull red bioluminescent glow.

Tail: Possesses a single tail fin, suggesting that swimming is difficult and requires substantial energy and food.

Behavior: Much slower than a Biter and has a smaller aggression range, possibly because it is partially or completely blind.

Hunting: Unlike Biters, Blighters do not form packs and instead hunt individually.

Sounds: Slowly patrols its territory while producing eerie screeches and hisses.

Attack: Attacks creatures that approach too closely, dealing 7 damage to the player.

Boneshark -

Appearance: Large head, gray body, and thick bone-like plates with orange markings along the head and edges of the plates.

Armor: Its irregular teeth are actually extensions of its exoskeleton, rather than normal teeth growing from gums.

Fins: Has two barbed pectoral fins and bony tail flukes, but no dorsal fin.

Eyes: Reflective green eyes with narrow, snake-like pupils.

Diet: Carnivorous, commonly hunting smaller fish such as Peepers and Boomerangs.

Behavior: Extremely aggressive and territorial, even attacking members of its own species.

Attack: Charges at targets while screeching. Its bite deals 30 damage to the player.

Defense: The Repulsion Cannon can be used to drive it away. Creature Decoys can distract it, but contrary to its databank description, it isn't actually attracted to light.

Reaction to attacks: When attacked, it turns toward the attacker and retaliates, often causing them to retreat.

Seamoth behavior: Particularly aggressive toward unoccupied Seamoths, repeatedly headbutting them for about 15% damage per hit. Interestingly, when a player is piloting the Seamoth, Bonesharks will usually ignore it.

Avoidance: Their speed makes swimming away difficult; getting into a submersible or using defensive equipment is generally safer.

Crabsnake -

Appearance: Long, serpentine body with two translucent, violet-glowing fins running from its neck to its tail.

Coloration: Bright pink upper body with reddish-brown horizontal stripes, a white underside, and numerous bright-purple growths along its back that may be Jellyshroom spores.

Head: Small rectangular mouth with two pairs of fang-like structures resembling crab pincers, plus two large black-tipped claws on the sides.

Eyes: Has no visible eyes.

Ambush Behavior: Usually hides upright inside a Jellyshroom and waits for creatures to approach before suddenly emerging and grabbing them.

Attack: Can trap the player similarly to a Reaper Leviathan's grab, making it particularly dangerous at close range.

Movement: After attacking, it may return to its Jellyshroom or leave to patrol and potentially find another mushroom.

Other Creatures: Will attack small fish that enter a Jellyshroom containing it.

Vehicles: Can damage the Seamoth slightly and the Prawn Suit only minimally, while generally ignoring the Cyclops.

Warning Behavior: If approached while inside a Jellyshroom by a submersible or Camera Drone, it may peek out and hiss rather than attack.

Eggs: Lays its eggs inside Jellyshrooms, where they can only be reached after the Crabsnake leaves.

When Injured: Shakes violently and may retreat into a nearby Jellyshroom for protection.

Stasis Rifle: The Stasis Rifle cannot affect it while it is inside a Jellyshroom.

Crabsquid -

Appearance: Has a translucent, bulbous outer membrane surrounding a hard brown-green body resembling a squid mantle.

Head: Four large blue eyes with black pupils and an unusual mandible.

Limbs: Has 10 smooth brown limbs. Eight are used for walking, while the two shorter limbs near its mouth form small pincers.

Movement: Swims by repeatedly inflating and deflating its transparent membrane, allowing sudden bursts of speed. It can also walk across the seabed.

Behavior: Highly aggressive and frequently produces loud clicking sounds. It hunts smaller creatures and can even attack Warpers.

Attack: Its physical attack deals 40 damage to the player.

Light Attraction: Crabsquids are strongly attracted to light. Flashlights, flares, Seaglide lights, and vehicle lights can draw their attention.

EMP Attack: When exposed to light, it can release a concentrated green electromagnetic pulse that temporarily disables electronics, vehicles, and Seabase power.

EMP Effects: Affected Batteries and Power Cells temporarily drop to 0% charge before recovering. Vehicles can also temporarily lose oxygen production.

Vehicle Threat: Particularly dangerous to the Prawn Suit, which cannot turn off its lights. A Crabsquid attacking a Seamoth can deal about 20% damage per hit.

Cyclops: Can damage the Cyclops, although its physical damage is relatively low. Its EMP can still disable systems, making escape difficult.

Captive Juveniles: Juvenile Crabsquids raised from eggs generally won't attack the player or submersibles, but they can still produce EMPs and attack hostile creatures such as Warpers.

Crashfish -

Appearance: Oval-shaped body with widely spaced nostrils, a large toothless-looking mouth, and one pale-yellow eye with a large black pupil.

Coloration: Red, scaly upper body with a smooth cream-colored face and underside.

Spikes: Covered in beige spikes with red tips. These contain the chemicals responsible for its explosive reaction and also form its fins.

Ambush: A nearby Sulfur Plant opens like a flower and produces a warning gurgle when it detects the player.

Attack: If the player continues approaching, the Crashfish launches from the plant and rapidly charges before exploding.

Speed: Extremely fast—fast enough to outrun a Seamoth and easily catch an unprepared player.

Damage: Its explosion can deal severe damage to the player, around 20% damage to a Seamoth, and about 5% to a Prawn Suit.

Avoidance: It has poor turning ability. Using obstacles and sudden changes in direction can help evade it.

Warning: Its distinctive "reeet" sound signals that it is becoming aggressive.

Sulfur Plants: If the player backs away after the warning, the Crashfish will retreat back inside its plant.

Eggs: Crashfish eggs can be found near Sulfur Plants, but nearby explosions can destroy them.

Alien Containment: Captive Crashfish won't explode inside Alien Containment. If released outside, they eventually swim away randomly and explode after roughly 20 seconds.

Lava Lizard -

Appearance: Large, heavily built body covered in scales, with pale-green skin and darker green patches on its back and a smoother beige underside.

Head: Two silver eyes in dark-pink sockets and a huge mouth with 16 pairs of teeth. The front two pairs are enlarged and protrude forward.

Limbs: Has two short, three-digit limbs with long claws and pink webbing.

Tail: A three-pronged, spike-tipped tail fin connected by pink webbing, plus two small clawed fins near the tail.

Scars: Covered in numerous scars, suggesting frequent territorial battles with other Lava Lizards.

Lava Armor: Can swim through lava and coat its back in hardened lava, creating a protective shell. The armor can be broken with a knife or Repulsion Cannon.

Projectile Attack: After swimming through lava, it can launch a cooled chunk of lava at the player and can follow up by ramming them.

Damage: Its attacks deal roughly 30% damage to the player.

Behavior: Extremely hostile toward Warpers and may abandon chasing the player to attack one instead. A single lava projectile can cause a Warper to teleport away.

Food: Its lava projectile can cook edible fish if it kills them.

Lava Larvae: Sometimes removes and eats Lava Larvae attached to the player's vehicle without damaging the vehicle.

Heat Resistance: Highly resistant to the Thermoblade, likely due to its adaptations to the Inactive Lava Zone and Lava Lakes, though a normal knife can still hurt it.

Masmer -

Appearance: Small, purple-shimmering body with four large bluish-white panels surrounded by translucent blue film.

Bioluminescence: The panels can glow green at night, with their patterns rippling and radiating when the Mesmer is hypnotizing prey.

Head: Bulky, speckled head with yellow sclera, unusual tilde-shaped pupils, and a teal mouth.

Movement: Uses two small teal flippers instead of a traditional tail.

Hidden Anatomy: When attacking, its head/body opens up, revealing a soft interior and four pink, tooth-covered stalks surrounding its actual toothless mouth.

Hypnosis: Can manipulate the player's perception, seemingly causing the PDA to encourage them to swim closer. Looking away or swimming backward far enough can break the effect.

Attack: Once its target gets close, it opens up and thrusts its spiked appendages forward, dealing about 35% of the player's health.

Hunting: Uses hypnosis to lure small creatures within striking range.

Defense: Can hypnotize and attack larger creatures, creatures of its own size, and even other Mesmers.

After Death: If killed while hypnotizing something, the hypnotic effect can reportedly continue temporarily until the target escapes, runs out of oxygen, or is interrupted.

Countermeasures: Swimming backward, looking away, or using a Propulsion Cannon/Repulsion Cannon can help break its influence.

River Prolwer -

Appearance: Long, narrow body covered with numerous protrusions along its top and underside.

Transparency: Most of its body is transparent, allowing parts of its spine and skeletal structure to be seen. It gives off a faint white bioluminescent glow.

Head: Fleshy red head with two round yellow eyes and a large jaw filled with sharp teeth.

Tendrils: Four long tendrils trail behind its head and are used to capture prey.

Hunting: Strikes prey with its tendrils, pulls the target toward itself, then attacks with its large jaw.

Behavior: Aggressive toward creatures that approach too closely.

Sounds: Produces eerie hisses and snarls when something enters its vicinity.

Sand Shark -

Appearance: Segmented body covered in a plated exoskeleton, with a grayish-violet back and pinkish underside.

Legs: Has 12 short, gray appendages arranged in two rows of six, which it uses to disturb and move through sand.

Head: Four orange eyes, a large fin-like structure on top, and a huge mouth containing six rows of sharp, jagged teeth extending down its throat.

Mouth: The inside of its mouth gives off an orange glow.

Ambush Hunting: Burrows beneath the sand and waits for prey to approach. Increasingly dense clouds of sand can reveal its location.

Warning: Produces low growls before attacking, giving nearby creatures a chance to retreat.

Attack: Bursts from the sand and rapidly chases its target.

Speed: Fast enough to catch a player swimming in a straight line, but changing direction repeatedly can help evade it.

Chase: If the target reaches safety or remains out of range long enough, the Sand Shark eventually gives up and returns to its territory.

Habitat: Primarily associated with sandy environments but can occasionally wander into areas such as the Jellyshroom Caves and Kelp Forest.

Combat: Doesn't dodge attacks effectively and usually swims straight toward its target, making it vulnerable to the Repulsion Cannon and Torpedo System.

When Attacked: Quickly flees until it reaches a safe distance from its attacker.

Stalker -

Appearance: Large, elongated body with smooth skin and a long, gharial-like snout.

Dorsal Plates: Seven plates run along its back from the neck toward the tail.

Fins: Has purple-tipped pectoral and pelvic fins and a broad, whale-like tail.

Attack: Its bite deals 30 damage to the player.

Vehicles: Will attack vehicles but can only actually damage the Seamoth.

Defense: If badly injured by a Survival Knife or Thermoblade, it will flee at high speed.

Metal Attraction: Stalkers have a strong fascination with metal. They can pick up Metal Salvage, Titanium, and Camera Drones, carry them around, and drop them elsewhere.

Teeth: Stalkers can lose teeth while attacking vehicles or manipulating objects. Their teeth are valuable because they're used to make Enameled Glass, an important material for advanced construction.

Feeding: Offering a catchable fish can temporarily pacify a Stalker.

Raised Stalkers: Stalkers hatched in Alien Containment remain generally passive toward the player, although they can still steal cameras and attack vehicles.

Warper -

Appearance: Flat, round head with a circular mandible-filled mouth and four small magenta-glowing eyes.

Body: Mostly covered by a thick purple cloak-like exterior over a translucent pale-blue body. Its internal structure includes a dark purple ribcage, glowing pink veins, and a visible heart-like organ.

Limbs: Has two spiked arms covered by transparent membranes and six lower tentacles, with two primarily used for propulsion.

Movement: Normally patrols slowly along curved paths, then suddenly changes direction with a sharp jerk.

Purpose: Actively searches for creatures infected with the Kharaa Bacterium, including the player.

Behavior toward the player: Depending on the player's infection stage, it may either observe them or attack.

Teleportation Orb: Can fire a fast projectile that teleports its target. Dodging it causes the orb to disappear, but the Warper may then pursue the target directly.

Melee Attack: At close range, it raises its claws and slams them down, dealing substantial damage. Its damage against the player varies with infection stage.

Projectiles: Can fire additional projectiles that deal 10 damage and rapidly pull the player next to the Warper.

Fauna Summoning: Can open portals to bring aggressive creatures from the surrounding biome into the fight. The number varies by creature size—from several tiny creatures to only one large creature at a time.

Vehicle Teleportation: Can forcibly teleport a player out of a Seamoth or Prawn Suit, leaving them exposed. It cannot remove a player from a Cyclops.

Stasis Rifle: Can temporarily freeze a Warper, but it will soon teleport away, limiting the weapon's usefulness.

Seamoth Defense: A charged Seamoth Perimeter Defense System attack can force a Warper to teleport away.

Overall: The Warper is dangerous not simply because of its attacks, but because its teleportation abilities can completely change the battlefield and remove the player's protection.
