The tail has the same length equal to the complete length of the shark. Here we use pelagic thresher shark Alopias pelagicus fin samples (N = 86) collected during a 4‐year period (2014–2017), and phylogenetic analyses, using the cytochrome oxidase I (COI), to determine the relative contribution of this species to the two largest shark fin trade hubs in the world, Hong Kong and Guangzhou, mainland China. Females are able to bear pups after they reach a size of about 81 ft (2.6 m). The pelagic thresher closely resembles, and is often confused with, the common thresher but can be distinguished from this species by the presence of dark patches of skin above the pectoral fin bases and by the absence of labial furrows.

Males are believed to reach maturity at 10 to 15 years of age, while females reach maturity even later. Thresher sharks are pelagic species that inhabit both oceanic and coastal water. They will occasionally swim into shallow waters or areas very close to shore, but this is relatively uncommon. This Pelagic Thresher Shark comes to the cleaning station early in the morning and to see them, we do sunrise dive as early as 5:30am. These sharks prefer open ocean habitats over continental shelves, coastal waters, but far from shore. Common threshers vary in color from coppery-brown to bronze color above, with metallic blue and purple hues. When at the cleaning station, they swim slowly in circles to allow the cleaner fishes to feed on the parasites on their body.
