The northern hooded shrimp (Betaeus harrimani) is named after the way its carapace partially covers its eyes (2). These shrimp reach lengths of 3.5 cm (1). Like other members of the Betaeus genus, the northern hooded shrimp lacks a rostrum, a beak-like structure at the front of the head, common in other shrimp (2). They are well camouflaged, transparent except for red pigmentation surround by blue spots, and quite agile making them quite elusive (1)(2). The northern hooded shrimp live in the low intertidal underneath rocks, logs and other debris (1).
