Abalone
Abalone (Haliotis) are ear-shaped gastropods with a row of respiratory holes and an iridescent nacreous interior used in inlay and jewellery; red abalone from California, pāua from New Zealand and perlemoen from South Africa are the well-known species. Polished shells are sold by the crate; large, undamaged wild red abalone shells over 25 cm are now scarce. Abalone poaching is a serious crime in South Africa and California.

CITES and protection
Abalone are not CITES-listed but are heavily regulated as fisheries: South Africa's Haliotis midae is subject to a CITES-style national permit system since poaching crises, California closed its recreational fishery in 2018, and New Zealand pāua shells require no permit but pāua meat does. Check the source of any large commercial lot.
Care (Byne's disease)
The nacreous interior is stable; the outer shell traps salts and is prone to efflorescence.
