Hermit crab one takes it over. For some larger marine species, supporting one or more sea anemones on the shell can scare away predators. The sea anemone benefits, because it is in position to consume fragments of the hermit crab's meals. Other very close symbiotic relationships are known from encrusting bryozoans and hermit crabs forming bryoliths. When properly sized gastropod shells are not available, hermit crabs have been known to resort to wearing other objects such as tree nut hulls or pieces of beach litter rather than go unprotected. This has become very common in some areas, due not only to the
Little hermit and some small insects. It feeds mainly by trap-lining. Little hermit The little hermit ("Phaethornis longuemareus") is a hummingbird that is a resident breeder in north-eastern Venezuela, northern Guyana, Suriname, French Guiana and Trinidad. This lowland species occurs in various semi-open wooded habitats, e.g. mangrove, secondary forest, plantations and scrub. In Trinidad it also occurs in rainforest. It is fairly common in most of its range, and therefore listed as Least Concern by BirdLife International. Previously, several other small hermits were considered subspecies of this species. This includes the stripe-throated hermit ("P. striigularis") of Central America and north-western South America,
