Two new species of porcelain crab, Porcellanella brevidentata and P. longiloba, have been discovered in northern Western Australia. These filter-feeding crabs live in symbiosis with sea pens and use feathery mouthparts to feed on plankton

A hitchhiker’s guide: Tiny, immobile creatures like barnacles can get a leg-up on competition by hitching a ride into the water current where there’s marine snow aplenty. The vehicle of choice here — Lithodes crab, a genus of king crab found throughout the global ocean. #uruguaysub200

Here we investigated the rock-boring barnacle Lithotrya from across their ranges. Using genetic data we reveal numerous lineages across the Indo-Pacific, with potentially 8 species needing to be named and described.

Time for a fabulous flatworm. This species has coloration similar to Pseudoceros scintillatus and P. zebra but not quite matching either. This specimen was found gliding along a reef known as the Third Sister in the Houtman Abrolhos Islands.

The filter feeding porcelain crabs can be exceptionally abundant, particularly these Lissoporcellana found on the reefs around the Houtman Abrolhos Islands.

Just a short clip to remind you how manic barnacle (Cirripedia) nauplius larvae are! For some reason, they remind me of muppets!

Great to be contributing to this exceptional Alliance
📣 BIG ANNOUNCEMENT! 📣

After less than 16 months exploring the ocean’s depths, we’re thrilled to reveal the first 866 new marine species discovered by the Ocean Census Alliance!

This isn’t only a significant step in documenting ocean #biodiversity. 👇

This newly discovered species is part of the Ocean Census mission of accelerating the discovery of marine life with an ambitious goal of discovering 100,000 species over the next decade.

This is Ocean Census Species Number 51.
