Hellish Bear-Shrimp

Conception
The hellish bear-shrimp is a rare phenomenon in which a fire-crested mantis shrimp becomes lost and finds itself in arctic waters, seeing no other option it lays it's eggs on the only land it can find and swims away. It is then that a polar bear comes and finds the eggs and seeing no other option sits on them as a chicken does for its eggs. The eggs are broken and out comes several hellish bear-shrimp which, seeing no other option, kill the polar bear and begins their lives. The fire-crested mantis shrimp and the polar bear do not need to be opposite sexes for this result to occur, and it is unknown how this happens.

Role as the Most Dangerous Animal on Earth
The hellish bear-shrimp is considered the most dangerous pseudanimal (and ordinary animal) on earth. It received this title after winning the most dangerous animal on earth competition, in which standard cows were placed in front of various other animals and they are timed to see how quickly they can kill the subject. The hellish bear-shrimp won with a record of 4.692 seconds, out doing the gas gerbil by 4.692 seconds. After this stellar achievement the hellish bear-shrimp was invited to a medal ceremony, where the hellish bear-shrimp, seeing no other option, killed all people and pseudanimals in attendance.

Anatomy and Biology
The hellish bear-shrimp looks like a regular polar bear, with hair all over it's body, save it's back and head which are covered in a 4.692-inch thick, bullet-proof shell like that of a shrimp. The tail is also like a shrimp and is curled curled over the bodies of the bear, these tails can spring forward at up to 469.2 kilometres per hour, being able to shatter thick plates of steel in a single blow.
