Blueband Hermit Crab

Fascinating facts about the Blueband Hermit Crab

• At just 40 mm long and a 19 mm carapace, this crab fits on the tip of a ruler, yet its tiny frame hides a bold color code. Its shell is brown or green, the antennae flash red, and adult legs end in bright blue bands that can turn white in youngsters.
• When the black turban snail drops its empty shell, the blueband hermit snaps it up like a ready-made house, preferring that specific design over any other. Inside that borrowed home it prowls at night, munching on drifting algae and the fronds of giant kelp Macrocystis pyrifera, plus any detritus it can find. Even in a lab, it will survive on the tough, ribbon-like seaweed Pelvetia canaliculata, showing how flexible its diet is while still relying on the same shell shelter for protection.
• During breeding season, a male will hitch a female onto his back and may keep her there for more than a day, turning the pair into a mobile nursery. The female then fills her borrowed shell with eggs from May to July, clutching them on her abdomen.
• Stretching from the icy shores of Alaska down to Punta Eugenia at the tip of Baja California, this crab. Early records mistakenly placed it in Japan, but those specimens were later re-identified as a different species, Pagurus filholi.
• Even a tiny hermit crab isn't safe from hungry fish; the pile perch, California sheephead, and spotted kelpfish all target it as a snack.
