A close up image of how the outer zooids differ a lot in morphology from the "inner" zooids

Meet Harmeria scutulata!

We don't see this species often (or at all) these days. Registered (Norwegian) specimens are pretty much 50-100 years old, and we actually have no recent record of this species here in Norway as far as I know.

Zooid size reduction in cyclostome bryozoans from the Late Triassic to the present‐day Body size evolution is a focus of palaeobiological interest, but few studies have examined long-term changes in the size of the modular zooids of colonial animals. Here we investigate changes in zooi...

Unlocking Mediterranean bryozoan diversity: seven new species unveiled after fixing a neotype for Fenestrulina malusii (Audouin & Savigny, 1826) (Cheilostomatida, Fenestrulinidae) Fenestrulina malusii (Audouin & Savigny), the type species of Fenestrulina Jullien, is among the most widely reported bryozoans globally. Following the loss of the original type material, presumed...

🌊 Phylum Friday: Bryozoa! 🌊

These small colonial organisms are usually found encrusting rocks or blending in with algae. However, many of the species found in New England are invasive, and have become a concern for intertidal and subtidal ecosystems as they encrust and out-compete native species.

yes, that is Triticella. That genus/clade is sometimes exclusively on crustaceans, often even their mouth parts. It has been shown that Triticella can synchronize its sexual reproduction to its crustacean host.

A close up of Triticella zooids. Thei have a long "stalk" and then you have the autozooid.

Today's cool museum collection discovery: Bryozoans growing on crustaceans!

I believe this ctenostome belongs to the genus Triticella, which is known to grow on specific groups of marine invertebrates 🦐
