Phylliroe bucephala is a parasitic species of pelagic nudibranch, a marine gastropod mollusc in the family Phylliroidae.

Biology

This species of nudibranch is transparent with its guts visible through the laterally flattened body. It has a tail and two long smooth rhinophores. It feeds on jellyfish and plankton as an adult. The juveniles parasitize Zanclea medusae.[1]

The eyes of the nautilus look more like pinholes more than anything, they lack a solid lens but they're capable of forming a dim image. The retina of Nautilus pompilius have the visual pigment rhodopsin, along with a peak absorption of 465 nm, and a small amount of retinochrome that helps regenerate rhodopsin for dim vision.[2]
