Definitively a trematode cercaria! It is most likely Bucephalus (Labratrena) minimus, which infects cockles:

The recently formed IUCN Parasite Specialist Group has just launched a Bluesky account. Give them a follow to get news about the conservation and amazing biology of parasites. Many parasite species are co-endangered with their hosts and need more conservation attention. 🌍🧪🪱

Unmasking the Sea Star Killer After a decade of carnage, we finally know what’s devastating sea stars along North America’s West Coast. Does that mean scientists can save them?

For @biographic.bsky.social, writer @craigwelch.bsky.social followed @hakai.org scientist @rhizalyssa.bsky.social's quest to unveil the the killer that decimated populations of sea stars off the West Coast. It took a few years but the lab's hard work paid off: www.biographic.com/unmasking-th...

We are so proud of our sea star wasting work that came out today. This interactive article is very complete and includes beautiful videos.

Host–Parasite Trophic Interactions as Revealed by Stable Isotope Analyses: Determinants for Trophic and Isotopic Niches of Hosts and Their Associated Parasites The analysis of stable isotopes (SIA) in organisms, especially those of carbon (13C/12C) and nitrogen (15N/14N), is a well-established and powerful tool for analysing trophic interactions between free...

🧬🐛 What can parasites teach us about food webs?
Stable isotope analysis (SIA) as a powerful tool now also in parasitology! Our chapter dives into how SIA and compound-specific SIA (CSIA) reveal what parasites eat and how they impact hosts metabolism and entire food webs. doi.org/10.1007/978-...

The title of the paper: "A minimum data standard for wildlife disease research and surveillance" - and an example data table

NEW! 🎉 We need wildlife disease surveillance to predict epidemics, but data sharing is rare - we found that only 2-3% of studies share raw data. So, we spent three years developing a data standard and R package to help get wildlife disease data into FAIR repositories. www.nature.com/articles/s41...

In a synthesis of over 3000 population trends in the Wadden Sea, we show a substantial reorganization of biodiversity with over 38% of populations undergoing significant change (i.e., increases or decreases), identify winners and losers and critical time points of change! dx.doi.org/10.1111/gcb....

<i>Sacculina pugettiae</i> Sacculina pilosella is a parasite of spider crabs ( Scyra ferox ), and while it is technically a barnacle, you're going to have to abandon ...

Two Barnacles, One Crab: 🦀
I've written a post about a pair of parasitic barnacles that infect spider crabs.

These barnacles grow roots that spread throughout the crab's body, some of which make their way into the host's brain.
