Cephalopods, such as the squid and octopus, have long been known for their wily intelligence. Their complex behaviors include unlocking and escaping from aquarium tanks, opening jars, and communicating with one another using a system similar to Morse code. These underwater creatures, along with cuttlefishes, are all coleoids, which is a subclass of cephalopods. New research highlights another unique ability of these underwater creatures: they can edit their own RNA. [Read more…]
