An ink dinoflagellate

Email   PrintPrint

Things have been a little tense lately… here, have a dinoflagellate! (kinda looks like a space ship, no?)

This ink drawing is based on Protoperidium, a dinoflagellate notable for its ‘pallium feeding‘: upon finding something tasty but awkwardly-shaped, it extrudes a ‘feeding veil’ in the form of a pseudopod-like structure, which then envelops the prey — whom awkwardness fails to save. Once safely inside this feeding extension, the prey gets dissolved and digested, and eventually only the inedible bits like diatom frustules get spat out. In a way, the dino extrudes its guts outside to devour what cannot fit through its mouth. So much for the poor algae who work so hard to stick together in chains too large to be eaten!

No matter how awkwardly large and cumbersome the mess may be in your life, may this dinoflagellate envelop and digest it away for you!
