Plesiosaurus 1933 01.jpg

A very stylized incarnation of this marine reptile eats Hellstrom as he attempts to flee at the end of Son of Kong. The 'snapping' version that grabbed Hellstrom was actually the revamped brontosaur from the original film; same holds for the armature version seen briefly snarling in predatory glee. When the island was sinking, the Elasmosaurus escaped with every other creature, but the other creatures died with Kiko.
