Friday Nudibranch Blogging


I don't know exactly which nudibranch this is...but I'm pretty certain it's some variety of Flabellina. Like most aeolids, they eat stinging cnidarins (e.g., jellyfish and anemones), and recycle the stinging cells into the cerata on their backs, where they remain functional against predators.

Wow, those are some nudi's. Gorgeous. And you say the stingingness of the jellies they eat still works in their own little blue selves? Amazing.

Thanks for posting such beautiful and amazing creatures. I'd never know of them if it weren't for you posting them.

They recycle the stinging cells? That is fucking amazing. We live in the most interesting place anyone could imagine

These lovely creatures never cease to amaze. Phila, do you have any idea how long the "recycled" cells work? That is just mind-boggling.

Green,

As far as I know, they can maintain 'em in good working order for as long as necessary. There's also some evidence, IIRC, that they alter their uptake of stinging cells to reflect changes in the predator population...different cells function in different ways, and some work better on certain predators than others.

Here's an interesting article on this process...it's one of the Mysteries of the Sea.

Mysteries of the Sea, indeed. Thanks for the info. As I said, mind-boggling.
