 Mainly nocturnal in habits , after dusk the leopard catshark hunts for small , benthic bony fishes and invertebrates in shallow water . In daytime , it generally rests inside caves and crevices , sometimes in groups . This species has been documented ambushing spawning chokka squid ( Loligo vulgaris reynaudi ) within their spawning grounds . Reproduction is oviparous and proceeds year @-@ round . Females produce rectangular , light @-@ colored egg capsules two at a time , attaching them to structures on the sea floor . Small and harmless , the leopard catshark adapts well to captivity and is often exhibited in public aquariums . It is caught by commercial and recreational fishers as bycatch , and often killed as a pest . The International Union for Conservation of Nature ( IUCN ) has listed this species as Data Deficient ; its numbers do not seem to be declining , but heavy human activity occurs within its native waters . The possibly fragmented nature of its distribution also merits caution for each local population .
