Monster Hunter Wiki

A formidable aquatic serpent that crests on moonlit nights—likely why it has often been mistaken for a mermaid. Despite its appearance, it is extremely aggressive, and tolerates no trespassers on its turf. It expels an intoxicating sleep powder from an organ on its neck, knocking out prey before it can resist.


Somnacanth is a Leviathan first introduced in Monster Hunter Rise.

Physiology

Somnacanth has a very unique physiology. Covering its body are large yellowish scales, transitioning to white on the underside. Its front feet have three digits, each one ending in a long, curved black claw. Its back feet have four digits that end in shorter claws. It has fins on each front leg. It has a short face with a disturbingly humanoid appearance. Above its eyes are a pair of large purple horns, with a pair of smaller knob-like protrusions in front of them. Adorning the side of its head are three pairs of small purple fins, with a massive crest-like fin on the top. These purple fins also appear along the top of its tail and form a crescent shape at the tip. It has a hard pad on its belly with a taiko drum-like pattern that it uses to crack open shells. It also features several bioluminescent patches on its body, which can be seen around its eyes, in the mouth, the seams on the throat, and the underside of the tail base.

Behavior and Abilities

Somnacanth can often be seen swimming on its back. It is capable of standing on its tail. It is a very territorial creature, tolerating no trespassers, and can become extremely aggressive.

Somnacanth is capable of producing a sleep-inducing powder in its throat and spraying it through the mouth. Similar to other monsters that can put creatures to sleep, it will use this opportunity to strike at its prey or adversary. It can breathe this powder out as a long ranged, sweeping cone or as a large cloud that covers the whole area. It is capable of jumping high into the air and slamming down on its target. It can also throw dart-like quills in rapid succession. The quills linger on the ground for a few seconds. The darts originate from the end of its crest.

During combat, Somnacanth has a tendency to stand on its tail, keeping its head hard to reach.

It can use its hard belly to crack open shells while laying on its back, similar to otters. These shells have a variety of effects when cracked open, including an explosion that covers hunter in blast powder, a directional flash and even a healing mist that also heals nearby hunters.

Threat Level (危険度): ★★★★★
Monster Hunter Now
A ferocious type of Leviathan. The sight of it at night, illuminated by moonlight, is often mistaken for a mermaid. It emits an anaesthetizing powder from its tail and the frill around its neck in order to cause prey to fall into a stupor. Some Somnacanth sightings tell of this species making use of unusual shells, so exercise caution if you catch one swimming towards you with a shell in its claws.

Hunting Tips

While in the water, it can move about as it pleases, but it doesn't fare so well on land, so draw it out to shore for an easy hunt. If you're caught in a cloud of its sleep powder, it's lights out; use a Wirebug to leap away from it and position for a counterattack.

While its appearance is as menacing as any monster in the series, the Somnacanth swims in style and has a mesmerizing singing voice. Ichinose says that the team looked at sea otters for Somnacanth’s way of swimming.
