In this episode, Randi and Nathaniel lose their damn minds over one of the coolest animals ever: the nudibranch. Nudibranchs are commonly called sea slugs, but they are actually gastropod molluscs. While they are born with shells, they shed them after their larval stage. More importantly, nudibranchs are the Kirby of the animal kingdom.
Nudibranchs are some of the brighter citizens of our oceans. I mean, they’re not smart–they’re just really colorful. Furthermore, there are over 2300 known species distributed throughout warmer parts of the ocean. Most species of nudibranchs are benthic, meaning they live on the ocean floor. There are a few species that swim in the water column, and then there are the glaucus nudibranchs, which swim upside down below the waterline. The most obvious feature of the nudibranch is the cerata, which are the rubbery looking appendages that grow out of the back of the nudibranch (the nudiback?). Join Randi and Nathaniel as they marvel over nudibranchs: their cerata (which in some species can store the venomous nematocysts from their prey), their ‘speech’ (there are some records of captive nudibranchs making clicking noises), and their sexual habits (google pictures plz). Tune in to find out if nudibranchs are great, or just okay.
