Dear Friends,
This image is a gift along with congratulations for my friend Krzysztof (cataclysta), as yesterday he successfully defended his PhD thesis in biology. The subject of his dissertation was diversity and ecology of Antarctic polychaets in Admiralty Bay. That is why I post an image of polychaete, however not an Antarctic one.


Nereis diversicolor - ragworm
(synonym: Hediste diversicolor)
Family: Nereidae
Order: Phyllodocida
Class: Polychaeta


It is one of the commonest intertidal polychaetes in estuaries of the North European coasts. Its body is flattened with a prominent dorsal blood vessel. Adults may reach 6-12 cm in length and consist of between 90-120 chaetae bearing segments (chaetigers). Appendages on the head are conspicuous consisting of two antennae, and two palps, and four pairs of tentacles. The paired parapodia have dorsal and ventral chaetae and are used for crawling and swimming. The colour varies. Mature worms become a brighter green approaching and during spawning, otherwise specimens appear to be a reddish orange or brown.

The species inhabits muddy substrata in a more-or-less permanent U or J-shaped burrow that may be up to 20 cm in depth. Also occurs under stones on mud where the burrow is adjacent to the stone.

Technical note: The animal is not alive, it is a conserved individual from our departmental collection used as teaching aid.

A rare sight in TN, even if the concerned group is not so rare in nature Michal, the preservative faded specimen still displays its beautiful form against a flattering, dark BG. Hope to see more (and living) members of this diverse group from you and/or from Dr. Pabis in the near future.
Cheers,
Mehmet
P.s.: Photographed a lot of polychaete specimens in B&W, both dead and alive, for a colleague in the first years of seventies, the biggest trouble was given by some Chaetopterus variopedatus specimens!

Hello Michal,
What a fine present for Krzys on getting his PhD!! Interesting to see this worm related to his work. A fine capture showing sharp details and clear colours against the dark background.
TFS and best wishes, Ulla

Hi Michal

This is a great post and a great news, too! Congrats to Krzys!!!
Polychaets are something extremely rare here on TN and i thank you for shading some light in this segment of zoology, too, with this post.
Even if this is a conserved specimen, i really like the way it's presented here - with excellent light on it and very good contrasting BG. The details are impeccable and the note is very educational as well.

Bravo and TFS
Horia

Hi Michal.
Precise work. Fantastic sharpness, details and lighting. Curve of the animal body and its shapes are amazing. Perfect job. My kind regards.
