Collar carpetshark

<em>Parascyllium collare</em>, the Collar Carpetshark, is a shark in the family Parascylliidae. This species is assessed as Least Concern on the IUCN Red List. The Collar Carpetshark is endemic to Australia, inhabiting shallow coastal waters along the southern and southeastern coast of the continent. Members of the genus <em>Parascyllium</em> are slender, bottom-dwelling sharks that typically rest on the seafloor during the day and are more active at night. They are generally small sharks that feed on invertebrates and small fish. The common name "Collar" likely refers to a distinctive patterning or band near the head region. Habitat description, geographic range details, and country-level occurrence data are not specified in available records for this species beyond its Least Concern status. Biological measurements including average length, weight, and lifespan, as well as diet and population estimates, are not provided in the available data. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern classification suggests the population is not currently under elevated extinction pressure.
