Hermit crab crab has several long spines, a long, narrow abdomen, and large fringed antennae. Several zoeal moults are followed by the final larval stage, the megalopa. Hermit crabs are often seen as a "throwaway pet" that would live only a few months, but species such as "Coenobita clypeatus" have a 23-year lifespan if properly treated, and some have lived longer than 32 years. Hermit crabs are more closely related to squat lobsters and porcelain crabs than they are to true crabs (Brachyura). However, the relationship of king crabs to the rest of Paguroidea is a highly contentious topic. Many studies based
Rufous-breasted hermit attached to the underside of a palm, fern or "Heliconia" leaf one or two meters (3–6 ft) above ground or so. The nests are often near a stream, waterfall or roadside, and are surprisingly easy to find. Incubation is 17 days with 23 more to fledging, and this species may nest up to four times in a season.
