#1377 - Maritigrella fuscopunctatus - Dusky Spotted Flatworm

AKA Eurylepta fuscopunctatus, and Pseudoceros fuscopunctatus. Another discovery by Andrea Watts at the Omeo Wreck here in Perth.

Initially I thought it was a nudibranch, going by the vivid colours, but I was quite wrong - it’s actually a Euryleptid flatworm.

Euryletids are free-swimming, active carnivores and scavengers, and feed by enveloping encrusting sponges and ascidians and pushing their stomach out through the mouth, which is also their anus.

They generally glide over the sea bottom but are also capable of swimming short distances by undulating their sides.  Common in shallow waters from Perth to Geographe Bay, but the colours and pattern can be surprisingly variable. The middle of the body may anything from orange to orange-brown to cream spots in a broad to narrow honeycomb pattern, or a single row of orange dots. Around the edges it can have large purple black (or sometimes creamy brown) spots (or blotches or sometimes as transverse lines) extending from the medial area in rows.

In Sweden, they occur on the west coast in the intertidal zone among algae and along with shells and stones at up to 200m depths. #animal #animals #djur #wildlife #naturliv #nature #preservedspecimen #flatworm #flatworms #invertebrate #invertebrates #naturhistoriska #naturalhistory #virvelmask #plattmask #marineflatworm #marineflatworms #animalia #platyhelminthes #cotylea #rhabditophora #polycladida #euryleptidae #Stylostomum #Stylostomumellipse (at Evolutionsmuseet) https://www.instagram.com/p/CZ1gnNxK83v/?utm_medium=tumblr

Taken 2022 22nd January, these are candy stripe flatworms (Prostheceraeus vittatus) @evolutionsmuseet being displayed. In Sweden, they occur on the west coast. They live in the intertidal to shallow subtidal zones hiding wherever possible, crawling over substrate using cilia, or gliding over it with sinuous motions. They will hunt other small invertebrates such as tunicates. #animal #animals #djur #wildlife #natur #naturliv #nature #naturalhistory #naturhistoriska #preservedspecimen #fauna #invertebrates #invertebrate #flatworm #flatworms #polyclad #polyclads #polycladflatworm #polycladflatworms #marineflatworm #marineflatworms #plattmaskar #plattmask #animalia #platyhelminthes #polycladida #euryleptidae #prostheceraeus #prostheceraeusvittatus #candystripedflatworm (at Evolutionsmuseet) https://www.instagram.com/p/CZaIIhiPNWY/?utm_medium=tumblr
