This is a composite image showing the emergence of a veliger (planktonic larva) of an Oregon hairy triton (Fusitriton oregonensis) from its shell. The mollusk was about 5mm in shell size, suggesting that it was nearly mature. Juveniles settle on the ocean floor after metamorphosis. Juveniles have been found at depths exceeding 2000m, while adults are generally found in waters of 800m or shallower. The larval stage of this species is around 4.5 years.
