Range of pygmy shark (in blue)

The pygmy shark (Euprotomicrus bispinatus), the second-smallest of all the shark species after the dwarf lanternshark, is a squaliform shark of the family Dalatiidae, the only member of the genus Euprotomicrus.[2] Their lengths are up to about 25 cm (10 in) for females and about 22 cm (8.7 in) for males.[3]

Pygmy sharks are ovoviviparous and produce about eight young in each litter.[4]

Conservation status[edit]

In June 2018 the New Zealand Department of Conservation classified the pygmy shark as "Not Threatened" with the qualifier "Secure Overseas" under the New Zealand Threat Classification System.[5]
