Two Articles About Crustaceans


“First Venomous Crustacean Discovered” by Matt Kaplan is about the Speleonectes tulumensis, which is the first crustacean to be discovered that uses venom to hunt their prey. It is a pale, blind, and tiny animal that lives in underground caves deep in the ocean. The caves are like a labyrinth, so it is difficult and dangerous for divers to navigate. The toxins in the venom of the Speleonectes tulumensis allow them to digest their prey and practically “drink them like milkshakes.” This discovery is big because they are the first crustaceans to be found to use venom to hunt their prey.

"How Mantis Shrimps Deliver Armour-shattering Punches without Breaking Their Fists" by Ed Yong is about how the mantis shrimp kills its prey. There are two types of mantis shrimp. There is the “spearer” species, which have hinged arms under their head, and there is the “smashers” species which have clubbed arms. Each specie punches at an average speed of 50 miles per hour, which is the fastest punch of any animal. The punch is so fast that it boils the water in front of them and creates a flash of light. The mantis shrimp delivers blow after blow of these destructive punches and kills its prey.
