#DidYouKnow there are more than 14,500 species of #copepods? Thats more copepods than #mammals (6k) or #birds (10k)! They are found in all habitats where water is found including oceans, lakes, caves, bromeliads, and even damp soil. They are also the most abundant animals in the ocean! 🦐🧪

Not every day that you get to describe something from a Megamouth 🦈 🧪
This species of parasitic copepod was first described in 1978 from a Megamouth off Hawaii and has only been collected a couple of times. Here we describe the male for the first time www.jstage.jst.go.jp/article/pbr/...

Two for one invertebrates for #InverteFest. Here is the nudibranch Hypselodoris tryoni, in Komodo Indonesia, where you can see the purple eggs of a parasitic copepod sticking out from the slug's gill pocket.

A yellow nudibranch see slug with dark purple spots. The spots have a white border around them. The slugs' mantle is has a purple edge. In the gills of the slug you can see some purple parasitic copepod eggs sticking out.

Excited to share our new paper on Kroyeria—a group of parasitic copepods found on sharks. Best part of the project was working with Greg Deets, who imo is the GOAT when it comes to copepod illustrations. We describe 5 new species & redescribe most others 🧪🦐

Mouth-attaching copepod Salmincola markewitschi reduces the body condition and growth of juvenile salmonids Salvelinus leucomaenis, by decreasing host feeding activity: evidence from parasite removal experiment

Murakami et al. buff.ly/0KgyRfb #OpenAccess

Ectoparasitic copepods in the genus Salmincola Wilson, 1915 are considered harmful to host salmonids, yet experimental studies on the mechanism by which these copepods affect hosts are critically limited.

to be honest, I do not know. Sometimes the organs of the copepods can get out of the body if crushed... But I honestly do not know what that can be.

World Association of Copepodologists @copepodology.bsky.social · Apr 14

yes, those are the spines from the legs (P1 to P5). Those are normal, and used for taxonomy!!

World Association of Copepodologists @copepodology.bsky.social · Apr 9

Pseudocyclopidae is named after the genus Pseudocyclops, while Pseudocyclopiidae from Pseudocyclopia.

Oh well.

World Association of Copepodologists @copepodology.bsky.social · Apr 9

Oh yes. One is one of the most ancestral lineages of Calanoida, and the other one one of the most derived. They do not even look similar.
