Dexamine thea

Blokkendam, the Netherlands, 6-5-2018. In vitro photo specimen A, 14-5-2018.

Identification by Marco Faasse (May, 2018): Not Lysianassa, as can be seen from the dorsal teeth on the hind segments, the long, inward-curving dactyli (outer segments of the legs), and the shape of the bases of the first antennae. This is Dexamine thea. This species sometimes lies among Hydrozoa/Bryozoa, with its dactyli around the branches and its back toward the substrate. Therefore, it tends to lie on its back more than other species. D. thea is not an exotic species in NW Europe. I found them quite regularly when I was collecting a lot of Hydrozoa/Bryozoa. You can't spot them with the naked eye. They can also be found among fine red algae.
