Thresher Shark (Hiu Tikus) Alopias pelagicus

Pelagic Thresher shark (Alopias pelagicus) has just risen from "Vulnerable (VU)" to "Endangered (EN)" from the International Union for Conservation of Nature (IUCN) red list of threatened species. Although International Concern is rising, their species still largely understudied with no conservation priority sites, no critical habitat identified, and no education and outreach.
