Harlequin shrimp (Hymenocera elegans)


About the subject:

This stunning but uncommon Harlequin shrimp (Hymenocera elegansis a delight to the eye. Most often found in pairs they live under rocks or in intertidal and subtidal coral reefs. They are territorial and monogamous for life. Pheromones emitted by the female keep the couple togetherHarlequin shrimp feed on starfish which they detect using scent. When they find a potential target they peel its arms from the substrate and turn it over to immobilize it. They feed on the delicate tube feet, starting at the tip of the arm eating their way up to the central disc in order to keep their victim alive as long as possible. For the same reason they sometimes even feed their prey.


About the picture:

To make sure the white and cream-coloured patches of the animal are not over-exposed it is important to check the histogram after you have taken the picture. If you do have blown out highlights the histogram will display a peak at the utmost right part of the graph. In this case adjust your exposure and try again.
