Day 20: Defending Against Rising Ocean Acidification

As we open the door on day 20, we look at a species in the Invertomics study category in the wild, and highlight a study from 2019 that places Platynereis in a modern context, to assess its capability to act as a model organism for studies of ocean […]

Day 15: What’s coming next year!

December is a time to reflect on the year that has passed, both the happy and sad, the success and the failures. But it’s also a time to look forward to the year ahead, new possibilities and opportunities. For me, this is especially important, as next time December […]

Teaching about sea squirts, worms and skeleton shrimps in Drøbak

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 […]

The mitochondrial gene order of Annelida – extremely old, but still working

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 […]

Group of the month: Feather duster worms (Annelida, Sabellidae)

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 […]

Door 7: New day, new species

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 […]

Group of the month: Spaghetti worms (Annelida, Terebellidae)

Text and pictures by Maël Grosse Among all the worm-like animals in the sea, polychaetes, or bristle worms, are probably the most diverse and striking group. This month is the opportunity to look at one of the most beautiful group of polychaetes (Fig. 1), the family Terebellidae Johnston, […]

The taxonomic challenge of the annelid genus Perinereis (Nereididae) just gets larger

Today, our paper about Perinereis species from the intertidal coasts of the Red Sea, Gulf of Suez and Suez Canal lead by Asmaa Haris Elgetany was published in ZooKeys. It is her third paper from her internship at our group and fittingly we are describing three new species […]
