Armien's Myotis

The Armien's Myotis, Myotis armiensis, is a species. Its conservation status is listed as Data Deficient, meaning insufficient information exists to assess its risk of extinction. Typically found in diverse terrestrial and aquatic ecosystems.

Great Hammerhead

The largest hammerhead shark species, great hammerheads reach up to 6 meters and are found in tropical and subtropical coastal waters worldwide. Their distinctive T-shaped head (cephalofoil) dramatically increases sensory surface area for electroreception, enabling them to detect buried stingrays through sand with exceptional precision — stingrays are a preferred prey. Critically Endangered, with populations declining dramatically due to highly valued fins and bycatch mortality.
