Cephalopods

Flamboyant Cuttlefish

Metasepia pfefferi · Cephalopod mollusk, family Sepiidae; a dwarf cuttlefish with a reduced internal cuttlebone

A flamboyant cuttlefish crossing a black-sand flat looks like a wind-up toy in ceremonial dress: a fist-sized animal ambling on two arm tips and skin flaps because its reduced internal cuttlebone barely floats it, pulsing waves of maroon, yellow, and white down its body as it goes. The pageant reads as warning coloration: laboratory work has reported significant toxins in its muscle, a rarity among cuttlefish, and the animal behaves like something with nothing to prove, hunting tiny shrimp and fish in open daylight with a deliberate tongue-flick strike of its feeding tentacles. At rest it fades to mud brown and simply disappears against the silt. Females glue eggs under coconut shells and rubble, and hatchlings emerge as perfect miniatures already flashing the family colors. It is a muck signature: ask the guides which slope has been producing.
