I’ve been a animals nerd for over three decades and sometimes I’m still just stunned speechless by the existence of an animal I didn’t know about

THIS IS GENUS PHYLLIROE.

IT EVOLVED JUST LIKE A FISH.

IT’S A GENUS OF SLUG.

So I did a post about these a while back, but here’s the main thing that I think is of major interest!

These nudibranchs attach themselves to a species of jellyfish in their larval stage, feeding on the bell, eventually outgrowing the jellyfish, consuming the tentacles of the host and then swimming away to carry on its life.

So not only are they free swimming, fish-like slugs, they’re parasitoids as well!

OH MY GOD we’ve got the FIRST EVER actual live footage of a gulper eel!!!

All previous videos have been of dead specimens floating around in tanks.

Nobody ever knew until now that they might float around with their mouth inflated like a goofy balloon like this.

It starts to “billow” mid-way through the video because of the deep sea rover’s jet stream and it puts up with that for quite a while before it finally gets too annoyed.
