marine slug

The Alabaster Nudibranch can be found in the temperate waters of the Pacific, from Alaska to California and along the coasts of Russia and Japan. The beautiful, wispy white tipped cerata are actually the animal’s lungs. But don’t let it’s delicate form fool you, this nudi’s jaws are strong enough to crack open the shell of a snail, one of its preferred meals - photo taken at Seattle, Washington


This friendly sea slug, called costasiella kuroshimae, is a very incredible species of ophistobranch! It is a sacoglass sea slug and is one of the few animals that can photosynthesize. I finally finished crocheting it and listed them on etsy! They make perfect gifts for scuba divers, marine biologists, and anyone who can appreciate the eccentricities of a green, photosynthetic sea creature! 

Available for adoption here. As always, crocheted with love. 

Valentine’s Day is coming up, but this is no ordinary rose – it’s a Hopkins’ rose! 

This bright pink sea slug can be spotted in the tidepools of Monterey Bay National Marine Sanctuary. When tidepooling in search of these little invertebrates, tread lightly! Tidepools are fragile habitats and it’s all too easy to crush their tiny inhabitants.

Name: Pectenodoris Aurora

My personal name: Agender femme slug (see previous post) 🌸🌹🌺🌼

Location: Philippines, Indonesia, Japan

Size: 0.8-1.2 cm long (smol)

Commonality: Rare (I’m guessing it’s rare considering how little information I was able to find :/)

Weird or cute? We think both! 

This is a warty sea slug, Dendrodoris warta – and it’s pretty easy to see how it gets its name. This sea slug, or nudibranch, was spotted in Gray’s Reef National Marine Sanctuary. 

What nudibranchs have you spotted while diving in your national marine sanctuaries?

Hey I just wanted to ask if you've ever heard of nudibranches! They're the family that includes sea slugs and some of them are... very yonic. Not to mention that some species fence with their peens to win a mate!

Yes! I love nudibranchs! I spend a fair bit of time on the sea, and there is nothing that makes my day quite the same way as happening across a nudibranch!

Nudibranchs are the frilliest, fluffiest, most multi-coloured sea dandies.

They don’t look quite real, right? Like something made out of candy or blown glass, wafting and wriggling through the sea.  Some nudibranchs get their vibrant hues from the things that they eat in an attempt to blend in with their environments - or let predators know that eating them would be a mistake.  This is called cryptic colouration.

Look at that.  Look at it.  Dale Chihuly in his wildest wet dreams could never invent that.

Nudibranchs exist all over the world, even in the Antarctic, and they come in all manner of wild varieties.

And some of them look like this:
