Amphiprion mccullochi

(Amphiprion mccullochi)

Description

Amphiprion mccullochi, also known as whitesnout anemonefish or McCulloch's anemonefish, is a species of anemonefish found in subtropical waters at Lord Howe Island and Norfolk Island.. It was named for Allan McCulloch, a former Curator of Fishes at the Australian Museum, Sydney. Like all anemonefishes it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host anemone. It is a sequential hermaphrodite with a strict sized based dominance hierarchy: the female is largest, the breeding male is second largest, and the male non-breeders get progressively smaller as the hierarchy descends. They exhibit protandry, meaning the breeding male will change to female if the sole breeding female dies, with the largest non-breeder becomes the breeding male.
