These samples were collected by the use of an oyster dredge towed by the ship Særún at 10-20 m water depth, in the archipelago off Stykkishólmur, Iceland.
Larger animals were photographed on a paper with 5 mm distance between the crossing lines. Smaller animals are epifauna organisms that were detached from the larger ones.

Water sample from depression on lapwing protection area. Sample taken on February 3rd at 3 p.m. Transferred part of the sample into a Petri dish today, February 8th.
The observed animal seems to have built a kind of protective shell that reminds me of caddis flies. You can see how it eats out in front and retreats when threatened.

Wasserprobe aus Senke auf Kiebitz-Schutzfläche. Probe entnommen am 3. Februar um 15 Uhr. Einen Teil der Probe heute 8. Februar in eine Petrischale umgefüllt.
Das beobachtete Tierchen scheint eine Art Schutzhülle gebaut zu haben, dass mich an Köcherfliegen erinnert. Es ist zu sehen wie es vorne raus frisst und sich bei Gefahr zurück zieht.
