Sabella spallanzanii is a species of marine polychaete, also known as a bristle worm. The worm secretes mucus that hardens to form a stiff, sandy tube that protrudes from the sand. It has two layers of feeding tentacles that can be retracted into the tube, and one of the layers forms a distinct spiral. By Marco Gargiulo

"So sure they just derp around eating jellies, sunning themselves at the ocean’s surface, and being gigantic all day long, but they aren’t useless and I LOVE THEMMMMMMM" Let's be real here for a second : You love every single thing in the ocean ! 😁

I mean, you’re not wrong 😝

Though some things are lower on the list…mostly aquarium pest species that make my life harder (bristle worms, aiptasia anemones, etc)

But everything else gets a ❤️ of approval in my book! Even the weird fish…no, ESPECIALLY the weird fish.



Oooh, I’m stepping outside of the box:  the vertebrate museum blog is featuring a post about INVERTEBRATES!  I will admit I know next to nothing about invertebrates.  The same goes for plants/botany – I can memorize and retain the most obscure nomenclature for non-native mammals, but ask me to tell the difference between types of pine trees and I’m stumped (no pun intended).  That does not mean I don’t have a growing appreciation for these things, it just means I need to allocate more brain power to biology and less to memorizing Battlestar Galactica trivia.

Many of you guys are marine scientists, entomologists, biologists, zoologists – lend me your knowledge!  Let’s turn the tables a bit – click the photos for short descriptions, and then why don’t YOU tell ME something about any of these fantastic creatures?
