Great Seminar with Tom Matthews organised by @islandbiology.bsky.social on: Assessing the wider implications of species extinctions: island birds and beyond May 27th, 4pm British Summer Time / 5pm CET Register (it's free) with this link: forms.gle/Cn1wUvukAp2Y...

The deep sea is home to various parasitic nematodes, and for many of them, we don't know what they infect. Trophomera is a genus of nematodes which live >7000 m below sea level, where they infect amphipods, priapuplids, mussels, and even other nematodes 🧪 dailyparasite.blogspot.com/2016/04/trop...

Circumoral spines on the oral sucker of a cryptogonimid (Trematoda) species.

Since I don't really look for copepods, I did not have a lot of specimens, but they are untouched since I am working with trematodes. So, I played around with some of them, but could not determine the ID rn since I have basically 0 knowledge on copepod taxonomy...

I've written a post on Pinnotheres pholadis, a species of pea crab, and it is about how a smol bean can stunt the growth of juvenile scallops 🧪 dailyparasite.blogspot.com/2026/03/pinn...

New book added to my collection. I wish I could do fieldwork to New Guinea!

Wormception: Veneriserva pygoclava is a worm with a name that translates into "Venus' servant" - but the truth is quite the opposite. It is a polychaete worm that has evolved to live as a parasite inside the body of other polychaete worms. #Invertebrate 🧪 dailyparasite.blogspot.com/2024/03/vene...

The ocean's Little Monsters: Monstrilloids are copepods with a peculiar life cycle. While the adults are planktonic, the juveniles are parasitic. They invade the bodies of invertebrates such as polychaete worms, and burst out of them xenomorph-style 🧪 dailyparasite.blogspot.com/2025/11/cymb...

Another paper was out in International Journal for Parasitology! We systematically reviewed the relationships between fish body condition and parasite infections, very common approach for elucidating negative impacts of parasites on host health

I've written a post about Galactosomum nagasakiense - a flashy fluke which lives rent-free in the heads of fish and literally gives them brain rot 🧪 dailyparasite.blogspot.com/2026/02/gala...

Found parasitic isopods from this nemipterid individual. The main problem is, I did not bring a larger tube with me...

For #WormWednesday This is Stomachicola sp., a digenean that recently emended to family level (Stomachicolidae) from Hemiuridae. Found in a stomach of a pike conger, Muraenesocidae. Very unusual form for a digenean!

Our new paper is now published! 🧪 "Cats, dogs, and sticky worms: invasion by land flatworms (Geoplanidae) is facilitated by household pets" doi.org/10.7717/peer...

Saw this wedgefish at landing site TPI Ujung Batu, Jepara, North Central Java. My friend, Erza, identified this as Rhynchobatus cf. springeri which is currently classified as critically endangered

You can see here that the caligid copepod (left) has slight purple coloration.

For #WormWednesday this is a trematode from the genus Hamacreadium that was isolated from a lutjanid host. You can see a juvenile one on the dorsal part of the individual.

Some parasitic copepods that I've recovered so far during fieldwork.

Back from a fantastic field trip at #HeronIsland Research Station. Such a great place for echinoderm enthusiasts (I counted 15 different species of sea cucumbers on the reef 🤩) Acanthaster picture taken by @Caleb Trimble

I haven’t posted for a while, because I just don’t know what to say anymore… But here are some prehistoric rock scratchings in Valcamonica that I found amazing, so maybe some of you will enjoy them too.

Managed to sneak in one paper before the New Year with coauthors @flyliceresearch.bsky.social and Daniel Gustafsson (not on Bsky)! Introducing 2 new species of bird-infesting lice that, despite having no wings, appear to be adept at jumping across bird hosts and continents! doi.org/10.1111/mve....

A new exciting paper on #sponge #evolution! Our results suggest that early sponges did not have #spicules and that both biosilicification and biocalcification evolved independently multiple times 🤯 www.science.org/doi/full/10....

#FossilFriday Graptolites are extremely useful as zonal fossils in the Ordovician and Silurian. Some look like pencil marks but better preserved examples, like this Monograptus priodon from the Wenlock of Scotland, resemble miniature saw blades.

My supervisor and her team just published a new paper "Symbiont Types of Scleractinian Corals in Java and Bali Waters, Indonesia". Molecular analysis showed that majority of the zooxanthellae (family Symbiodiniaceae) belong to the genus Cladocopium with small fraction of Durusdinium.

“For too long, a significant part of our past held beyond everyday reach of Indonesian society. Scholars discussed it, museums displayed it, global narrative was shaped around it, yet the Indonesian people could not see them at home. That era ends today.” -Fadli Zon 🏺

Big Croakers vs Big Suckers: I've written a post about an outbreak of Limnotrachelobdella okae leech at a croaker farm off the coast of Raoping County, and how those big leeches and their bloody appetite caused a mass fish die-off #Invertebrate 🧪 dailyparasite.blogspot.com/2026/01/limn...

The coolest things that no one is talking about. What if we told you there were giant single cells in #deepsea that can reach over 20 cm www.deepseapod.com/episodes/065 📸 NOAA public domain 1 of 3

Our eLetter github.com/caseywdunn/s... responding to a recent Science paper was just posted. The paper found more genes with consistent support for sponge-sister than ctenophore-sister. We found several technical issues that, when corrected, reverse the conclusions and recover ctenophore-sister.

Hexametra angusticaecoides is a nematode worm that usually infects lizards, (see: dailyparasite.blogspot.com/2020/08/hexa...) but this study found bats infected with this worm, possibly from eating insect prey which are usually eaten by lizards. #Invertebrate 🧪 www.sciencedirect.com/science/arti...

Forskalia from @schmidtocean.bsky.social dive 651. So perfectly designed to catch prey. I love them. #sepacificseamounts #MarineLife

Yesterday was the last day in Cibinong, at least I already finished with my first scientific illustrations. Now, back with writing my manuscript...

Almost took me a month to complete a drawing for a single specimen 💀. I really need to practice drawing...

An (ecto)parasitic #Crustmas. This is Dolops (above), which swims around and attaches to fishes (below), but unlike its relative Argulus, which has suckers, it has hooks to hold on. Also, is bizarrely cute! 🧪🦑

Did you think hermit crabs always live in snail shells? 🧪🦀 Some deep sea hermit species live symbiotically with anemones that DISSOLVE the shell and SECRETE a new one ("carcinoecium") made of chitin! The carcinoecium has evolved at least 3 times! Photo credits in alt text. @megdaly.bsky.social

Fun fact, a lot of wonderful scientific illustrations you see in the 19th century natural science publications, were done by women, usually spouses of the researchers as uncredited free labour. The famous finches, came from John Gould, his wife, Elizabeth, illustrated his ornithology books.

Astaghfirullah, went to Blok M for a quick cash grab, but ended up eyeing a secondhand bookstore and now I've got unexpected expenses. At least I've got Stephen Jay Gould's book now...
