The Reaper Leviathan often swims deeper down but not quite at the seafloor. It also seems to circle its prey (or more commonly the player) for a few moments before attacking and often strikes from behind by surprise. According to the data bank entry, this roar is a form of echolocation, though it does not function like this in-game. The Reaper Leviathan emits loud, echoing roars audible from great distances. Therefore extreme caution should be taken while exploring those biomes. There are 25 reaper leviathans in Subnautica 7 in the mountains, 8 in the dunes and 10 in the crash zone.

SPAWN COMMANDS SUBNAUTICA EGGS SKIN
Multiple scars can be seen on the body, particularly around the facial area, and the blueish-white skin appears similar in texture to human skin. It has two maroon mandibles on each side of its face which slowly get darker, tipped with black claws, four in total. Its head features a horn (most likely used for ramming its prey), a large mouth housing many teeth, as well as two pairs of eyes with grey sclera. The fins and other red areas of the body possess slight bioluminescence. Most of its fins, along with its back, are red in color. It also has two dorsal fins running along the length of its entire body, and two ventral fins taking a small portion of its belly.

The Reaper Leviathan possesses a long, slim, muscular body with four caudal fins and two pectoral fins. Fins and mandibles included, the creature is just a little longer than a Cyclops submarine. The Reaper Leviathan is a massive creature.
