Living on live bivalve shells, this is poorly documented hydrozoa has unique body plan

their relationship are possibly like this, the hydroids are using bivalve as locomotion, meanwhile the bivalve are protected because the hydroids has nematocyst

Apparently today is World Bivalve Day - yay! - so here are some of the bivalves from my old shell collection. I’m hoping the IDs are correct 🤞

I'm sorry, WUT. There are bivalve snails?! 🧪

We’ve looked at snails with one shell and slugs with no shells. Now let’s have a look at a snail with two shells, because Nature laughs at our puny attempts to pigeonhole.

In today’s #AtoZ – J is for Julia (Juliidae) (1/9)

Small, perky snail with head poking out between its two shells. The snail has a pair of long, tubular tentacles. The shells are like clam shells, except they are vivid green. The hinge is at the top.

The shell and snail are both very bright green. The snail has white blotches on its back.

A Piddock riddled Hagstone.
Hagstones are stones with naturally formed holes in them. In this case made by a type of stone burrowing marine bivalve called a Common Piddock (Pholas dactylus).

Hope to update soon on Fossil Ridge Trail by Beverly Glen (closed since '90s) but I did hike another Fossil Ridge Trail near Topanga at Stunt & Saddle Peak Rds. Mostly bivalve imprints on rocks & shells, millions of years old from when the SM Mtns were under the ocean. Very cool!

Many species of bivalve change sex. Many start as male and become female/hermaphroditic. Some, vice versa. Some change back and forth annually

It's Bivalve Day. And what's better than a bivalve? One that hosts a worm too!

Meet Bathymodiolus platifrons (the mussel), and it's very close friend, Branchipolynoe pettiboneae, a scale worm.
