Abstract
The distribution (habitat preference) of the holothurian I. badionotus (Selenka) on the Bermuda platform is related primarily to shelter from wave action. Within sheltered habitats I. badionotus occupies stable rocky, sandy or muddy substrates with epibenthic epibenthic biota. I. badionotus of similar size are unselective feeders with regard to particle size of muddy of sandy sediments. I. badionotus can ingest its own feces, which may provide a potentially enriched food resource that is unlikely to persist in areas of turbulent water conditions. The 1st summary of knowledge on stichopodid feeding is provided. The absence of deposit-feeding holothurians co-occurring with I. badionotus may allow the latter to occupy so many different sheltered habitats, because in more tropical reef flat habitats coexisting holothurian species have better defined habitat and sediment-food requirements.
