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 […]

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, […]

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 […]

Suddenly it’s already November, so let us introduce another cool animal in the FEZ blog. This time you can learn about an enigmatic little-known group: the acoels. Acoela is an order of tiny flattened unsegmented worms, belonging to the phylum Xenacoelomorpha (pronounced “zenacelomorpha”). They live mainly in benthic […]

Gnathostomuida, also known as “lesser jaw worms”, is a phylum of about 100 described species of minute marine worms. The first gnathostomulid was discovered in 1928, in the fine sand of Kiel (Germany), by Adolf Remane. Later, Riedl (1969) elevated the animal group to the rank of phylum. […]

Summer is here, so it’s time for the Artsdatabanken project team to go back to the field. Or to the sea, in our case. After driving 500km from the east to the west coast, through beautiful mountains and majestic fjords, we arrived at Austevoll (Figure 1), an archipelago […]

Spooky scary skeleton shrimp, send shivers down your spine, their appearance will shock your soul, but certainly don’t seal your doom tonight! Family Caprellidea, otherwise known as skeleton shrimp, are small marine arthropods that are found world-wide. Using their specialized ‘feet’, called pereopods, these slender, segmented invertebrates cling […]

The phylum Kinorhyncha – often referred to as mud dragons – includes exclusively marine meiofaunal species. Meiofauna or meiobenthos comprises animals that are characterized by size (> 45 μm and < 1mm) in order to discriminate them from micro- and macrofauna. Accordingly, Kinorhyncha are usually < 1 mm in […]

By now, everyone knows that a lot of us in FEZ are working with marine invertebrates. But why? Aren’t these just weird worms that do nothing but crawl on the ocean floor? Not really, and I’ll try to explain why. From the 34 phyla of the Animal kingdom, […]
