#FossilFriday Fine specimen of the problematical fossil Dickinsonia costata from the Ediacaran. On display at the South Australia Museum, Adelaide.

Finally the source of my financial crisis have arrived ❤

Treat myself with an ice cream

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.

Parasitic helminth found in the recently deceased Java Rhino translocated to Ujung Kulon National Park Indonesia. From press release at Ujung Kulon National Park instagram page.

Codonobdella is a genus of leech found in the depths of Lake Baikal - there are three different species, and unlike most leeches which feed on vertebrate animals, Codonobdella is a parasite of amphipods #Invertebrate 🧪 www.sciencedirect.com/science/arti...

Hear ye, hear ye! Come get your biblically accurate crustacean from the deep, named after the Greek goddess of victory. #Invertebrate 🧪 dailyparasite.blogspot.com/2023/05/dend...

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...

I've written a post about a tiny monster, a copepod which is monstrous by name and by nature. It has no mouth and it must mate. As a juvenile, it lives in the body of a worm, and when it reaches adulthood, it pops out like a tiny xenomorph. #Invertebrate 🧪 dailyparasite.blogspot.com/2025/11/cymb...

Did you know. That the meme-explosion that was the wooden model of Sacabambaspis (an Ordovician jawless fish) held at a Museum in Helsinki, was created by a pioneering Estonian fish paleontologist and palaeoartist, Elga Mark-Kurik. 🧵

Relic worms for relic fishes: Gyrocotylideans are an ancient group of parasitic flatworms which are related to tapeworms. Appropriately enough, these frilly worms live in the gut of an ancient host - the holocephalans (ratfish), also known as Chimaeras #Invertebrate 🧪 www.nature.com/articles/s41...

#MolluscMonday Balanced on a wall beneath the ice-cream parlour at Aubeterre (Charente, France) is a fossil of the large rudist bivalve Hippurites, probably collected from a local field underlain by Campanian limestones.

How much stress would a wood beetle get if the wood beetle was filled with worms? Horned passalus beetles can have dozens to thousands of worms squirming inside them - and these worms can affect how their host responds to stress #invertebrate 🧪 dailyparasite.blogspot.com/2023/06/chon...

This particular lutjanid individual was co-infected by three ectoparasitic groups, lernanthropid copepods, gnathiid isopods, and monogeneans

⚡Shocking truth⚡ about fish lice: I've written a post about Dolops discoidalis, a species of fish louse which also happens to be the first ectoparasite to be documented from the electric eel 🧪 #Invertebrate dailyparasite.blogspot.com/2025/10/dolo...

Hirudinella is a genus of stomach flukes which are usually associated with the Wahoo. But species in this genus can be found in a wide range of pelagic fishes, including the Pacific bluefin tuna 🧪 #Invertebrate www.researchgate.net/publication/...

My friend who is studying in Germany gifted me this book. Thank you 🥺

Crouching Parrot, Hidden Louse: The Kyloring (Pezoporus flaviventris) is a critically endangered species of Australian parrot, and it is host to Forficuloecus pezopori - a species of louse which lives only on the Kyloring and nowhere else. #Invertebrate 🧪 dailyparasite.blogspot.com/2024/06/forf...

There's a species of apicomplexan parasite called Siedleckia nematoides which looks like microscopic version of those soft plastic grub fishing lure🧪 journals.plos.org/plosone/arti...

This is my first time seeing alive lernanthropid copepod (possibly Lernanthropus latis)!

Some little circus performers. #protistsonsky

#MolluscMonday Photographed at Hampton Court Palace last week, orthocone nautiloids in paving slabs of Swedish Ordovician limestone. A microfault crosses the chambered phragmocone of one. The other fossil may represent a siphuncular structure but comments would be welcomed.

Some parasitic copepods and a gnathiid isopod that I found during fieldwork in Alor.

#WormWednesday Two digeneans recovered from the GI-tract of a sciaenid host.

A new addition to my collection 👀

Talking about another true #invertefest: belemnite "battlefields" or "Schlachtfelder". Despite the name, they are generally used to refer to dense accumulations of #fossil #cephalopod rostra, which can be formed under various mechanisms. Irrespectively, they are a great way to obtain large samples.

The shark-sucker barnacle - Anelasma squalicola - is a barnacle with an unusual habit. Instead of filter feeding on plankton, it has evolved to parasitise deep sea squaloid sharks such as lantern sharks and Greenland shark 🦈 #Invertebrate 🧪 dailyparasite.blogspot.com/2014/09/anel...

This is such a cool project!

I've written a post about Myxobolus medusae - a myxozoan parasite that lives in the eyes of red-bellied piranhas. Beauty might be in the eye of the beholder, but this microscopic medusa is in the eye of a piranha #Invertebrate 🧪 dailyparasite.blogspot.com/2025/08/myxo...

Honeyguides are natural-born killers - like cuckoos, they are brood parasites, and the first thing going through the mind of a honeyguide chick when it hatches from its egg is: MURDER royalsocietypublishing.org/doi/10.1098/... 🧪

From a lecture I'm currently writing about the history of #Invertebrate taxonomy. Those myxozoans do be tricky 🧪

Hello my friend, good to see you again. You are right on time (according to my ~4 years of monitoring data). #protistsonsky #radiolaria

That's me there 😂

Just completed the 5th International Workshop on Symbiotic Copepoda in Malaysia! Gained hands-on skills in copepod taxonomy, field collection, specimen dissection, and parasite data analysis plus presented my Lepeophtheirus ID key project.

I learned today that not ONLY are there cases of "two headed" sea cucumbers? but there are also sea cucumbers with TWO ASSES! HA! beat that! #NAEC2025 North American Echinoderm Conference! #echinoday
