Kapala stingaree
The Kapala stingaree (''Urolophus kapalensis'') is a species of stingray in the family Urolophidae, endemic to inshore waters off southeastern Queensland and New South Wales. It is commonly found on and around rocky reefs at a depth of . Reaching in length, the Kapala stingaree has a rounded, diamond-shaped pectoral fin disc and a slender tail, which ends in a leaf-shaped caudal fin and bears lateral skin folds and a small dorsal fin in front of the stinging spine. It has a distinctive bell-shaped curtain of skin between its nostrils. This species is greenish above, with a highly variable pattern of dark markings usually found outside and between the eyes, and over the back and tail.
Crustaceans, in particular shrimp and amphipods, constitute the predominant prey of the Kapala stingaree; small bony fishes and polychaete worms are also eaten. It is aplacental viviparous, with females normally gestating only one pup at a time, and provisioning it with histotroph ("uterine milk"). The International Union for Conservation of Nature (IUCN) has assessed this species as Near Threatened; it is regularly taken incidentally by commercial fisheries, and is unlikely to be resilient against fishing pressure due to its low fecundity and propensity for aborting its young when captured.
==Taxonomy==
Commonwealth Scientific and Industrial Research Organisation (CSIRO) researchers Gordon Yearsley and Peter Last described the Kapala stingaree, previously termed ''Urolophus'' "sp. A", in a 2006 issue of the scientific journal ''Zootaxa''. They named the new species in honor of the research ship FRV ''Kapala'', which conducted a series of fishery surveys off New South Wales in 1980s and 1990s that contributed substantially to ichthyological knowledge. On November 14, 1984, the ''Kapala'' collected the type specimen of this species, an adult male long, from the Tasman Sea off Jervis Bay. This ray may also be referred to as the banded stingaree.〔
