Abstract(s)
Despite low biological diversity, many endemic species are present in Cape Verde.
There are five species of lobsters: Panulirus regius, Panulirus echinatus, Palinurus
charlestoni (endemic species), Scyllarides latus and recently Panulirus argus was found
for the first time. Lobsters are interesting from the scientific point of view, and they also
provide the means of subsistence for many families. In this work, the behavior of the
lobster species was studied, in particular intra and interspecific cohabitation. The
shelters and lobsters were marked and observed using diving. Three shelters were
observed in the island of SĂŁo Vicente and two in Santo AntĂŁo. Cohabitation was
observed in most shelters, up to fifteen individuals of P. regius in a single shelter, and
three species (P. regius, P. echinatus, e S. latus). Marked lobsters were not present in
the area one day after marking, suggesting they moved to another site, since predation
due to fishing or natural predators is unlikely (no fishing and few predators present).
Three month after, again none of the marked lobsters were observed, and the numbers
present were higher. The knowledge of the movement patterns, behavior and habitat is
relevant for the regulation of the fishing activity (periods with no fishing and marine
protected areas).
