302:. It can form swarms, dense aggregations of individuals, and these have been observed in shallow water over sandy bottoms, above patches of algae in reef areas and over algae on rocky shores. They also form swarms in sunlit patches of water among mangrove roots at the edge of lagoons in the Caribbean where they have reached densities of 90 copepods per ml (0.034 fl oz).

in Belize. It was found that swarms only formed by day, with the individuals dispersing at night. Swarms were denser in June than in
January and consisted of adults and late-stage larvae. In nearby open water younger larvae predominated during the day and swarming did not take place. In a current of

up to 2 cm (0.8 in), the swarm maintains its position, usually in a position where a beam of sunlight penetrates the canopy. There is an energy cost in maintaining the swarm in a particular location and each individual faces greater competition for food which makes the

of this behaviour unclear. Swarming may provide greater breeding opportunities, reduce the chance of involuntary dispersal by the current and protect against predation. In fact, there are few planktivorous fish feeding on this copepod among the mangroves and the main
