Don’t Mess with a Mantis Shrimp
Mantis Shrimp, previously mentioned in episode 373 as a critter with some amazing body armor, has another reason to be feared. The shrimp that employ a large club-like smashing mechanism actually have spring-loaded motion like a catapult, performing at a whopping 10-23 m/s, whereas those that spear their prey use shear muscle force at perform at 2-6 m/s. Watch out, little fishes!

Who Needs Sex?!
Bdelloid rotifers have reproduced asexually for millions of years. How are they still around? By stealing genes from other organisms. Around 10% of their DNA is acquired through horizontal gene transfer. 39% of the DNA that codes for enzymes are from a foreign source. Who needs sex, indeed?
