Optimal and Anti-Predator Foraging in the Sand Bubbler Crab Scopimera inflata (Decapoda: Ocypodidae)
Sand bubbler crabs Scopimera inflata are central place foragers that spend long periods feeding on nutritionally poor surface sediment adjacent to their burrows. Individuals make series of excursions from their burrows usually moving progressively in clockwise or anticlockwise directions so that they feed on areas of ‘‘virgin’’ sediment on successive forages. However, they foraged further from the burrow than was predicted by a model of central place foraging. Foraging crabs were under...[Show more]
