葉海麒麟是一種海蛞蝓,多義裸鰓類，無殼類 海蛞蝓科家族中的洋 腹足綱 軟體動物。[2]

Distribution

This species is widely distributed throughout the Indo-West 太平洋s including the central Pacific and the 紅海.[3]

Description

This is a large species growing to at least 115 mm. It can be distinguished by its numerous (3 to 6), longitudinal, tuberculate notal ridges. The ridge and bases of the tubercles are a blue-grey colour. The tubercles are capped in yellow. The foot sole has a black longitudinal foot stripe. The rhinophoral clavus possesses 27 to 30 lamellae.[4]

Mimicry

Juveniles of the 海參, Pearsonothuria graeffei are brightly coloured and closely resemble Phyllidia varicosa. They are white and blue or black, with a few large, yellow, thorn-like projections. These bright colours warn 捕食 of the 毒性 of the nudibranch, and this 擬態 on the part of the sea cucumber species serves to protect it also. The adult sea cucumber has much duller colouration, but it is also much larger than the sea slug and has its own toxic chemicals at this stage.[5]
