Lore

Teleosaurus is a relic of the Jurassic seas, a predator that dominated shallow coastal waters long before humans walked the land. Its long, armored body and powerful tail made it a master of ambush, striking silently from beneath the surface. Fossilized remains show evidence of a diet dominated by fish and squid-like cephalopods, suggesting it thrived in rich estuaries and lagoons. Sailors of legend tell of “iron-jawed beasts” lurking near reefs and wrecks, dragging entire crews beneath the waves. In coastal ecosystems, Teleosaurus ruled as an apex predator, shaping marine life with its relentless hunting strategies.

Traits

• Keen Smell. The Teleosaurus has advantage on Wisdom (Perception) checks that rely on smell.
• Aquatic Stealth. While motionless in water, the Teleosaurus is indistinguishable from a floating log or rock formation. It has advantage on Dexterity (Stealth) checks made to hide in aquatic terrain.

---

Actions

• Multiattack. The Teleosaurus makes two attacks: one with its bite and one with its tail.
• Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 21 (3d10 + 5) piercing damage. If the target is Medium or smaller, it is grappled (escape DC 16). Until this grapple ends, the Teleosaurus can’t bite another target.
• Tail Swipe. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 16 (2d10 + 5) bludgeoning damage. If the target is a creature, it must succeed on a DC 15 Strength saving throw or be knocked prone.
• Death Roll (Recharge 4–6). While grappling a creature, the Teleosaurus violently twists. Each creature it is grappling takes 27 (6d8) bludgeoning damage and must succeed on a DC 16 Strength saving throw or be restrained until the grapple ends.

---

Reactions

• Thrash Reflex. When a creature within 5 feet misses the Teleosaurus with a melee attack, it can make one Tail Swipe attack against that creature.

---

Legendary Actions

The Teleosaurus can take 2 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature’s turn. It regains spent legendary actions at the start of its turn.

• Detect. The Teleosaurus makes a Wisdom (Perception) check.
• Surge (Costs 2 Actions). The Teleosaurus moves up to half its swimming speed without provoking opportunity attacks.
• Drag Under. The Teleosaurus pulls one creature it is grappling up to 20 feet deeper underwater. The creature must succeed on a DC 16 Constitution saving throw or begin to suffocate as per drowning rules.

Tactics

A patient ambush predator, Teleosaurus waits in kelp, reefs, or wreckage, striking suddenly with Bite and Death Roll to maximize damage. Tail Swipe controls space and knocks foes prone, while Drag Under isolates prey. Against groups, it exploits water terrain to separate enemies. When injured or outmatched, it uses Surge to retreat into deeper waters where few can follow.

Teleosaurus

Teleosaurus has a thin, streamlined snout filled with needle-like teeth and a long, flat tail that it uses to propel itself through the water.

SPECIAL ABILITIES

Death Dive (Ex)

When grappling a foe of its size or smaller, a marine crocodile can perform a deadly dive upon making a successful grapple check. As it clings to its foe, it uses the force of its powerful tail to propel it downward in the water, allowing it to use both the move and damage actions as part of its grapple attempt. If successful, the marine crocodile maintains its grapple.

Hold Breath (Ex)

A marine crocodile can hold its breath a number of rounds equal to 8 times its Constitution score before it risks drowning.

ECOLOGY

Environment tropical oceans
Organization solitary, pair, or float (3–6)
Treasure none

The marine crocodile resembles its land-based cousins in general body shape and size, though its legs are a hybrid of webbed feet and nascent fins. Its long tail is thinner and flatter than those of traditional crocodilians, allowing the marine crocodile to swim with alarming speed as it whips its tail back and forth.

Marine crocodiles generally remain in warm, shallow oceans and seas. They spend most of their time at sea hunting fish, sea mammals, aquatic humanoids, and monstrous humanoids like merfolk, sahuagin, and locathahs. Only when breeding and laying eggs do marine crocodiles venture onto land (where they are slow and clumsy), before returning to the sea.
