Plesioth

Plesioth is a large water wyvern commonly found in jungles and desert water caves. Plesioth has shiny blue scales and  a body structure similar to sharks. They are commonly seen in the water, but have adapted legs for hunting. When they're weak, the Plesioth's top fin flattens against their head.

Plesioths have a grand taste for frogs, fishing with one can lure them so that they can get pulled out of the water, which has the added bonus of damaging them and leaving them open to your attacks. Another way to get them out of the water is to throw a sonic bomb over them, although the chance is 50/50.

Plesioth have a water stream attack, that although predictable, it does great damage if hit. They have quick speed, especially when running. Like some of the other monsters, they have a hipcheck attack, which takes a wide range around it. They also have the ability to put hunters to sleep when they jump over you when coming from the water.

Plesioth are most weak to the thunder element. Plesioth's most sensitive areas are its head and neck.

They share a close evolutionary lineage with the Cephadrome. There is also a subspecies known as the Green Plesioth.

Plesioth first appeared in Monster Hunter.
