When tunicates attack! In the dark depths, predatory tunicates have abandoned passive filter-feeding to trap and digest prey ambush style! #marinelife

Regular reminder:
- Barnacles are crustaceans.
- Tunicates are chordates (same phylum as YOU).

My single best shot from dockfouling in Morro Bay, CA: a giant acorn barnacle (Balanus nubilus) with cirri extended, surrounded by a cluster of aptly named lightbulb tunicates (Clavelina huntsmani). B. nubilus is the world's largest barnacle species; this one is the size of an apple. 🦑🦀📸OlympusTG6
An underwater photograph of a giant acorn barnacle, perhaps the size of a small apple, open with its reddish segmented tentacle-like cirri are extended briefly to filter feed before being retracted. The barnacle is surrounded by dozens of curious looking tunicates (sea squirts) that are clearish white with a pair of orangish pink luminescent filament like organs - giving the species its name, the lightbulb tunicate, as it resembles a lightbulb. The water column is a greenish turquoise.

Years ago I was obsessed with these Antarctic "tulips"-eventually learned they were TUNICATES, Molgula pedunculata #tunicateTuesday Such crazy lookin' things! www.researchgate.net/publication/...

A colony of tunicates from Lembeh

A colony of blue, translucent tube-shaped animals. Each has a yellow ring at the upper end.

A baby sea squirt! Ascidiacea tunicates have a ‘tadpole’ life-stage which can be very brief, but super cute! 🦑 #plankton

Can you believe these are animals? Chordate animals, even.

Star tunicates (Botryllus schlosseri).

Star-shaped colonies of sea squirts or tunicates, on the surface of a stone. They lie flat against the stone surface and are covered in a gelatinous layer.

Is there a more disappointing politician right now in Australian politics than @senatorwong.bsky.social?

Like tunicates, it seems Labor MPs fail to ever fully develop a spine.

Predatory tunicates at the Monterey Bay Aquarium

#TunicateTuesday #MarineLife #Invertebrates #DeepSea #Megalodicopia #MBARI #MontereyCanyon #Photography #WestCoast
Two predatory tunicates that are white tubular gelatinous creatures that stretch into the water with mouths that behave similarly to what you would find with a Venus flytrap. They are on rocks and additional rocks can be seen behind them in an aquarium.

Predatory tunicates look like innocent sacs but ambush passing shrimp. You might think they’re simple filter feeders—until they go full bitey sock puppet on their prey.

Week 4 of November's #insertaninvert2024 - in remote parts of the coastal country people still gather tunicates the old way.

We asked how the urchins "dressed" themselves. @echinoblog.bsky.social writes, "Is the urchin doing it, or have the tunicates somehow affixed themselves? It's possible that, for some reason, the urchins are using their tube feet and/or pedicellariae to adhere the tunicates."

Extremely wild missing context: these are tunicates, meaning chordates. They are in the same phylum as YOU!

Today’s sparkling species is 𝙋𝙮𝙧𝙤𝙨𝙤𝙢𝙖 𝙖𝙩𝙡𝙖𝙣𝙩𝙞𝙘𝙪𝙢, sometimes called a sea pickle.

This glowing gelatinous tube is actually a colony of tiny animals – zooids – joined together as a single colonial structure. Each zooid possesses two luminescent organs which rhythmically flash bright blue-green light.

Star Ascidians (Botryllus schlosseri) - colonial tunicates. Small star shaped colonies where each "star arm" is an individual tunicate.
