About Antiopella longidentata (Gosliner, 1981)
The medallion silvertip nudibranch, scientifically known as Antiopella longidentata (Gosliner, 1981), grows up to 40 millimeters in total length. It has a pale body, with dark to tan colored cerata that have white tips. Its rhinophores are white and rolled. An opaque white spherical mass of unknown function, called the rhinophoral crest, sits between the two rhinophores. This species is endemic to the South African coast. It is found on both sides of the Cape Peninsula, ranging from the intertidal border down to at least 30 meters depth. This nudibranch feeds on a bryozoan, the spiral moss animal Menipea triseriata. Its own egg mass is a flat spiral of capsules, containing 5 to 7 eggs per capsule. The egg ribbon of the Cape silvertip nudibranch is globular, convoluted, and holds numerous eggs per capsule.
