Looking for skeletons

One of the pleasures of underwater photography is learning about sea life which many divers don’t even know exist. The Skeleton Shrimp (Caprella linearis) is one such species. They are not exactly tiny (up to 2cm long) and are actually really quite common. It’s just that they are very difficult to see. They spend their lives clinging to other sea life, grabbing food particles from the water. They are usually seen on hydroids, because they are easy to spot there, though they inhabit many other hosts which get them into the current, such as Dead Men’s Fingers, but are much harder to spot on those.

So it was, I spent a very enjoyable dive in Loch Creran recently hunting for these critters. They have often been photographed before and I wanted to make a different kind of image to what I had seen previously. By using a high-power diopter, I concentrated on just the head of the creature, shooting across the hydroid fronds. Shooting an abundant species allowed me to hunt down a suitable rock with a conveniently placed hydroid, so I could shoot without disturbing the fine silt ubiquitous at this site. I like this shot because it shows the shrimp through the fronds of the hydroid, like an elusive jungle animal seen through the undergrowth. The shallow depth of field of the diopter ensures subject separation by throwing the hydroid out of focus.

On the other hand, this second capture unintentionally caught the shrimp with its claw arms wide. It made me smile because whereas the first image seemed to say “you can’t see me”, the second seemed to say “Ta-da! Here I am!!”
