Do cookie cutter sharks have bioluminescence: Cookiecutter sharks are able to produce bioluminescence on their ventral side, the underside of an organism, due to tiny light producing organs called photophores.

Mantis shrimp, or stomatopods, are carnivorous marine crustaceans of the order Stomatopoda, branching from other members of the class Malacostraca around 340 million years ago. Mantis shrimps typically grow to around 10 cm in length, while a few can reach up to 38 cm. Wikipedia

Class: Malacostraca

Order: Stomatopoda; Latreille, 1817

Phylum: Arthropoda

Kingdom: Animalia

Subphylum: Crustacea

Eyes: The quirks of mantis shrimp vision. The mantis shrimp's visual system is unique in the animal kingdom. Mantis shrimps, scientifically known as stomatopods, have compound eyes, a bit like a bee or a fly, made up of 10,000 small photoreceptive units.


Can a mantis shrimp hurt a human: A mantis shrimp's powerful punch can hurt humans. A shrimp can land before a person even realizes it is there because its strike is so quick. Shrimp punches cause deep wounds and lacerations with rounded edges. There is almost always a loss of tissue after a mantis strike and heavy bleeding.
