The spotted estuary smooth-hound or rig (Mustelus lenticulatus; Māori: makō)[2] is a houndshark of the family Triakidae, found on the continental shelves and in estuaries around New Zealand.[3] It is closely related to the gummy shark (Mustelus antarcticus) of Australia.[4] Males can grow up to a length of 125 cm (49 in), while females can reach a length of 151 cm (59 in).[3] In 2025, rigs were found to be the first known shark species capable of active sound production, namely, "clicks."[5]

It is commercially fished, and is commonly served in fish and chip shops in New Zealand under the name "lemonfish".[6] In June 2018 the New Zealand Department of Conservation classified the spotted estuary smooth-hound as "not threatened" with the qualifier "conservation dependent" under the New Zealand Threat Classification System.[7]

Names

In English, Mustelus lenticulatus is commonly known as the gummy shark, lemonfish, rig, spotted dogfish or spotted smooth-hound, with its full name being the spotted estuary smooth-hound. In the indigenous Māori language, the name for the species is makō.[2] It is also known as mangō,[8] pioke[9] or pīokeoke[10] in Māori, though these are generic terms, with the former being used for any shark (particularly the school shark) and the latter two being generic terms for dogfish sharks.
