Biology Munidopsis is an opportunistic omnivore, feeding on detritus, diatoms, or dead animals. These animals are negatively phototactic and can be found hiding in crevices and under rocks during periods of the day when portions of the caves are illuminated. During the night, M. polymorpha come out to feed, and at this time densities can reach higher than 150 individuals per square meter in Jameos del Agua. Munidopsis is territorial, basing individual territories according to the length of their second antenna, giving each individual sufficient room to graze. When an individual invades another’s territory, its presence is detected by their antennae and the invader is aggressively attacked with extended chelipeds. [details]

Reproduction Munidopsis polymorpha has separate sexes, although the population in Jameos del Agua is dominated by females. Males can grow slightly larger than the females. The only distinction between sexes is the genital pore present at the base of the third pair of thoracic legs in the females. Reproduction takes place throughout the year, although more ovigerous females can be found in Spring. The eggs are relatively large, containing a higher quantity of yolk than other investigated species of Munidopsis. Eggs have a diameter of 1.2-1.3 mm and are yellowish in color. Each female is typically found with 1-3 eggs but has been observed carrying up to 8-10 eggs ventrally in the pleon. Ovigerous females continuously clean and oxygenate the eggs with their fifth pair of pereiopods. Females take care of the embryos until the first stage, the zoea, when at this point, they are released. After 10-14 days post release from the female, the zoea molts into a second zoea stage (Fig. 62). Both zoea stages are very similar, measuring around 3 mm and can only be distinguished by details in the morphology of the pleopods. In the first larval stages, eyes are present, but they are partially covered by the base of the large and dorsally concave rostrum. These first stages are non-feeding and are nourished by a large supply of yolk. Both stages are benthic and are almost unable to move except for small movements achieved by beating of the pleon with the larvae telson. After 3-4 weeks, the second zoea stage of Munidopsis polymorpha molts into a small squat lobster which is morphologically similar to the adult. At this point, the yolk is still not completely consumed. [details]
