Squat Urchin Shrimp

Gnathophylloides mineri

The Squat Urchin Shrimp is a small crustacean belonging to the family Palaemonidae and order Decapoda. It is typically found in subtropical regions, with a distribution spanning the Arctic, Indo-Pacific, and Western Atlantic. This shrimp is primarily benthic, residing at depths ranging from the surface to 94 meters, though most are found shallower than 40 meters and many even at depths less than 10 meters. The reproductive behavior of the Squat Urchin Shrimp involves a precopulatory courtship ritual, which is common among decapods. This process involves olfactory and tactile cues, often leading to indirect sperm transfer. The species is gonochoric, meaning individuals are distinctly male or female. Divers encountering the Squat Urchin Shrimp may find it in habitats such as coral reefs, rocky reefs, and reef walls. Its cryptic nature might make it challenging to spot, as it likely blends into its surroundings.
