Eurydice pulchra

Eurydice pulchra, the speckled sea louse, is a species of isopod crustacean found in the northeast Atlantic Ocean. The generic name is for the nymph Eurydice of Greek mythology; the specific name means beautiful in Latin. The range of the species extends from Norway to the Atlantic coast of Morocco, but not into the Mediterranean Sea. It lives in the intertidal zone on sandy shores. It has large eyes and long antennae, is grey to brown in colour, and has black spots (each one a chromatophore) on all its body surfaces. Males grow up to 8 millimetres (0.31 in), while females reach 6.5 millimetres (0.26 in).
