Like all other abalone, Haliotis asinina is a member of a large molluscan class, the Gastropoda which are characterized by having single-piece. The abalone, Haliotis asinina, is a large, highly active tropical abalone that feeds at night on shallow coral reefs where oxygen levels of the water may be low. Feeding, growth and survival of hatchery-bred juvenile abalone, Haliotis asinina ( mean initial shell lengths: 32 mm) stocked at 25, 50 and m-2 of shelter.

The color may variate between green olive or brown externally, with distinct roughly triangular patches. They graze amongst turf algae and inhabit the undersides of boulders and coral bommies.

The protoconch remains developmentally inert until the animal contacts a specific cue that initiates the process of metamorphosis. Overall, ontogenetic changes in Haliotis asinina shell pigmentation and structure match changes in the habitats occupied during development.
A sensory structure, the epipodium, is an extension of the foot that bears tentacles and projects beyond the shell edge in the living abalone. Retrieved from ” https: Haliotis asinum Donovan This abalone dwells in shallow water coral reef areas of the intertidal and sublittoral zones, commonly reaching a depth around 10 m.

The Asses Ear abalone is in the haliotid family which are edible marine snails and comprise around species worldwide Miller et at Essentials of fish nutrition, feeds, and feeding of tropical aquatic species- Aquaculture Department, Southeast Asian Fisheries Development Center.
This shell pattern may enhance the juvenile’s ability to camouflage on the heterogeneous background of the CCA they inhabit at this stage of development.
They have a pair of bipectinate ctenidia which are well-developed epipodial tentacles and a rhipidoglossate radula Lindberg The growth rate of Haliotis asinina is the fastest of all the abalones. The juvenile Haliotis asinina teloconch rapidly develops a uniform maroon colouration several weeks after metamorphosis, similar to the crustose coralline algae CCA that the larva has settled upon.
As is the case in many other abalones, the interior surface of the shell is strongly iridescentwith shades of pink and green.
The white arrow indicates the metamorphosis from the larval shell protoconch to juvenile shell. The postlarval shell teleoconch is laid down rapidly following metamorphosis with marked variation in the rate of its production between individuals. Copyright Duc Minh Luu.

The adductor muscle is a delicacy in parts of the world which has led to it being extensively harvested from the wild. In larger shells, a ventral cap of CaCO 3 that underlies the tablets of aragonitic nacre continues to thicken. They all have pores along the outer edge of the shell which are distinguishing features.
Furthermore, it is at this stage of development that the first recognisable tablets of nacre can be asknina.
