保育: Perissodus paradoxus 由国际自然保护联盟（IUCN）在濒危物种红色名录中为自然保育而进行了评估 evaluated (LC) 无危（Least Concern） (2006). P. paradoxus is encountered chasing its quarry on almost any dive near or over a sandy bottom in any part of the lake. It is so common that there is no threat to its existence even though it is easily caught in a net.
