Fiddler crab claw, the smaller one will begin to grow larger and the lost claw will regenerate into a new (small) claw. For at least some species of fiddler crabs, however, the small claw remains small, while the larger claw regenerates over a period of several molts, being about half its former size after the first molt. The female fiddler carries her eggs in a mass on the underside of her body. She remains in her burrow during a two-week gestation period, after which she ventures out to release her eggs into the receding tide. The larvae remain planktonic for a further
Saw-billed hermit to the typical hummingbirds, Trochilinae (Hinkelmann, 1999). This, coupled with the considerable number of autapomorphies such as the unusual bill, suggest it is the most primitive species of the hermit lineage; a situation paralleled by the equally unusual tooth-billed hummingbird in the Trochilinae. Saw-billed hermit The saw-billed hermit ("Ramphodon naevius") is a hummingbird from southeastern Brazil, the only member of the genus Ramphodon. It is around 14–16 cm long and is one of the heaviest of the hermits; its straight bill has a hooked tip. It lives in humid forests, where it aggressively defends feeding routes ("trap-lines") from individuals of
