A sea rhinoceros is a fictional sea creature featured in an episode of "SpongeBob SquarePants." According to the online SpongeBob encyclopedia, the sea rhinoceros has the body of a large sea turtle with the tail of a shark, the head of a rhinoceros and two spikes on its back.
The Sea Rhinoceros appeared in the SpongeBob episode "The Camping Episode." The rhinoceros was notorious for attacking creatures who had already been attacked by the sea bear. The only way other characters could defend themselves from a sea-rhinoceros attack was by wearing special anti-sea rhinoceros undergarments. The voice of the sea rhinoceros is played by Dee Bradley Baker.
