Don’t be Crabby!

ecapod crustaceans in Costa Rica comprise a major variety of the marine life, having at least 549 different species recorded in the coastal and marine waters. While the bulk of these are Brachyura (crabs), Anomura (hermit crabs/king crabs/ etc), and Caridea (caridean shrimp), it is one of the smaller order of decapods, the Achelata, which garners the most interest; lobster being quite popular amongst lovers of shellfish dishes.
Costa Rica boasts at least nine recorded species of Achelata (sometimes referred to as palinura, langustas, langouste, or rock lobsters) and includes spiny lobsters, slipper lobsters, furry lobsters, and other fossil relatives. (The name derives from the Greek and the fact that the members of this group do not have claws (a- = “not,” chela = “claw”). Most of the species are edible but, according to some sources, the taste of many slipper lobster species are not as favored as they hide under the mud during the day. The furry
lobsters are small with long antennae and may easily avoid traps, so are not commonly found on menus. This probably makes the spiny lobsters the most commonly caught variety locally, and globally they are known as an economically significant food source. They are, in fact, the largest food export of the Bahamas.
Spiny lobsters can be easily distinguished from true lobsters by their lack of claws and their thick spiny antennae; though they appear similar they are not closely related. The spiny lobster can be found in most of the warm seas of the world, tending to live in the crevices of coral reefs and other rocky areas. The local spiny lobster varieties will commonly range in size from 20 through 40 cm. They venture out at night to feed on a diet of snails, clams, crabs, and other bottom food. They are usually a sign of a healthy ecology. These types of lobsters are well known for their mass migrations following rainstorms, sometimes in groups of as many as 50, traveling in a long line across the sea
