Erling Svensen This black list species - Caprella mutica - photographes at Smøla - Norway today.

Cynthia D. Trowbridge introduced from Japan, right

Wendy Northway Stunning detail!

Claire Goodwin Great picture Erling!

Andrew Mackie True Alien photo!

Rudolf Svensen Japanese Skeleton Shrimp (Caprella mutica). Nikon D300 in Subal Housing. 2 Subtronic flashes, manual settings, 60mm Micro Nikkor, 1/200, f/22, iso 100

Chris Spence Looks like he has been taking steriods and forgot to work on his legs! Super Pose!

Rudolf Svensen Thanks. Yes, its a he, the she's are much smaller. This is an animal we do not want in Norway and it is listed on the Norwegian "black list" but I think it is impossible to get read of them.

Chris Spence Hmm Introduced species are an extreme problem world wide! :-(

Ken Thongpila Very nice shot :-) and love the story to go with too...

Amedeo Altomare amazing :O

Anna DeLoach I love skeleton shrimp!

Carol Horne These two little beings were in the branches of the hydroid pictured here and the larger one on the right would have been circa 2mm, the smaller one <1mm. The large one was using the very long 'antennae' to 'whip' the smaller one - couldn't tell if it was attacking it or feeding it. Also on the branches were numerous small brown 'baskets' containing other plankton, which I couldn't get to see, and which the larger being here was again either attacking or feeding. Although possibly too indistinct to see, the large one was very flexible, long and thin body and the length of the 'feelers' it used was as long as itself. The paddle like front legs are clearly visible. I don't even know what to call it, so if someone could point me to a website or reference I'd be very pleased to research it myself. Thanks

Marco Faasse They are skeleton shrimps. It's even possible to see which species: Pseudoprotella phasma. Often seen on this type of hydroid.

Carol Horne Hey, brilliant....how do you know all this? Recommend a reference site?

Marco Faasse I would recommend the Hayward&Ryland book (Marine Fauna of the British Isles). Seems difficult at first but contains a wealth of information. Collins pocket guide to the seashore seems easier but is far less complete. Good sites are the Habitas site: http://www.habitas.org.uk/marinelife/ and the one I'll mention in the next reply.

Marco Faasse This one: http://www.marlin.ac.uk/species.php

Tony Gilbert Yes, it should be the Pseudoprotella phasma as Marco has mentioned. We get a lot of these all over the sponges and hydroids especially in spring time. They are in their millions I reckon. The issue is getting a good shot: http://www.flickr.com/photos/tonyjgilbert-images/7408199806/in/photostream/ I've photographed them with eggs as well. There is another Species, invasive, called Caprella mutica.

Niki Lacey Anyone got any amphipod jokes??

Natalia L. Demchenko Amphipodologist is studying life cycle of Caprella mutica and looking in stereomicroscope. Specimens are saying to amphipodologist "we also have private life like you!!!"

Indiana Jackson hahhaha....the joke is:we do not have private life!

Natalia L. Demchenko actually it's joke about microbiologist and microbes...I adapted it for our Amphipod Croup;-)

Denis Copilas a Phronima walks into a bar and the bartender says: Hey man, why the long face?

Niki Lacey Yes! Excellent!
