Yesterday, we published an preprint on the meiofauna and why it is important to study them and which scientific questions should be addressed next. The publication involved 42 researchers from 44 institutions all around the world. The research was initiated and led by Alejandro Martínez and Diego Fontaneto […]

As part of the ArtsDatabanken project “Assessing biodiversity in the marine algae belt“, we taught a class of eager students and consultants about the species of our project. The course did not only comprise theoretical lectures, but really hands-on experience. We went out to different spots in Drøbak […]

This month at the blog, we wish to present Hydroza, which is a class found within phylum Cnidaria. This lesser-known taxa is perhaps more known than thought, as well-known species like Portuguese man-o-wars (Physalia physalis), the freshwater genus Hydra, fire coral (Milleporidae), and by-the-wind sailors (Velella velella). Also, […]

Mitochondria are the energy plant of our cells. Originally, they were bacteria, but then they were captured by the ancestors of eukaryotes (among others all animals, mushrooms and plants) and used to produce energy for the cell. This is also known as the endosymbiotic theory. An inheritance from […]

This month it is time for another group of polychaetes, the family Sabellidae. Sabellids are present from intertidal to abyssal marine waters all around the world (Rouse et al. 2022). They inhabit both soft substrates such as sand or mud and hard substrates such as rocks or coral […]

This month’s group of animals on the spotlight are nemerteans, also known as ribbon worms, vermiform creatures belonging to the phylum Nemertea. They include more than 1300 species, typically long and slender with soft contractile bodies. Most nemerteans are marine, predominantly benthic or bottom dwellers, but some species […]

This month’s ”Group of the month” is a bit of shameless self-promotion. I will present an animal group today, where we conduct quite a lot of research on. However, it is nonetheless really interesting and worth to learn more about it. The family Parergodrilidae belongs to the annelids […]

For my second entry in our advent calendar, I will again present a taxonomic paper. This time it is surprisingly not about worms, but about a rather intriguing group of crustaceans, Facetotecta (Figure 1). It is a small group of about 14 species, all in the genus Hansenocaris. […]

Another paper I really enjoyed reading this year was “Sampling multiple life stages significantly increases estimates of marine biodiversity”, published last April by Svetlana Maslakova and her colleagues. They argue that most surveys of marine life underestimate the total number of species because they rely almost entirely on […]

One of my favourite papers this year is, logically, about two of my favourite topics: taxonomy and worms. In this paper, Lavesque et al. revise the family Terebellidae sensu stricto (a part of the spaghetti worms I presented in a previous blog post) in French waters. They review […]
