Say “hello!” to the straight tooth weasel shark (Paragaleus tengi), a species once identified as Negogaleus tengi, but was subsequently moved to the genus Paragaleus. According to the IUCN profile on this animal, there is a similar species that occurs off Malaysian Borneo and Indonesia and has previously been considered to be conspecific with P. tengi (White et al. 2006) but recent investigation suggests they are different taxa. Part of the Hemigaleidae family, they are an inshore, small shark found from Japan to southern China in the western Pacific Ocean.
The straight tooth weasel shark reaches about 92 cm in length, is viviparous and gives birth to litters of two pups, but little else is known of its biology. They are listed as Data Deficient (DD) because we know so little about them! But they are taken in small numbers as bycatch in various fisheries throughout their range, so more studies should be done on them- sooner rather than later!
