Abstract

Behavioral interactions among newly settled postlarval and fifth instar lobsters in a simulated cobble environment were quantified. Seven behavioral categories were identified and the proportion of time spent in each was evaluated. Transition matrices for three general behavior categories were evaluated for the postlarval and fifth instar. Postlarval and fifth instar lobsters displayed different behavioral patterns. Postlarvae spent a large proportion of time walking on the sand substrate and excavating shelters, whereas fifth instar lobsters spent the majority of time excavating and sitting in shelters. Agonistic interactions between early benthic stage lobsters were similar to those described for older juvenile and adult lobsters. Dominance hierarchies, burrow invasion and eviction of subdominant individuals were observed in both the postlarval and fifth instar.
