Feeding Macrobrachium crenulatum

This video depicts one of my male Macrobrachium crenulatum, a Palaemonid prawn from a high-elevation stream in northeastern Puerto Rico, as it feeds on blackworms (Lumbriculus variegatus).

Note the asymmetry and strong bristles of the second pair of chelipeds — traits which are less pronounced in females and immature specimens. Coloration is fairly similar to that exhibited by this specimen from Panama, but other males may exhibit red in place of yellow.
