The physical properties of shelter and biotic factors associated with shelter selection were studied in the Mediterranean slipper lobster Scyllarides latus (Latreille) in both the field and laboratory. In laboratory experiments, lobster significantly preferred a shaded cover or an opaque shelter to a transparent shelter of the same dimensions. No preference was exhibited by lobsters between a shaded transparent shelter and an opaque shelter. Lobsters also demonstrated a significant preference for shelters with more than one opening and for those that were in a horizontal as opposed to vertical position. They also tended to shelter together with other conspecifics. S. latus preference for horizontal dens with a small entrance, close to the substratum and with multi-openings were observed in natural and artificial reefs. Tendencies for cohabitation, shelter sharing with moray cels, and bringing clams to the shelter after night foraging, were also etected among field lobsters. No correlations between the various sheltering behaviors and sex or size of lobsters were found. It is suggested that these characteristics are anti-predator adaptations of S. latus which lack any morphology for active defense.
