Dusky Shark (Carcharhinus obscurus) – Near Threatened/Vulnerable
The dusky shark is a species of requiem shark that can be found in tropical and warm-temperate continental seas worldwide. One of the largest members of its genus, the dusky shark reaches 4.2 m (14 ft) in length and 347 kg (765 lb) in weight. “The International Union for Conservation of Nature (IUCN) has assessed this species as Near Threatened worldwide and Vulnerable in the northwestern Atlantic and the Gulf of Mexico. The American Fisheries Society has also assessed North American dusky shark populations as Vulnerable. Its very low reproductive rate renders the dusky shark extremely susceptible to overfishing. Stocks off the eastern United States are severely overfished; a 2006 stock assessment survey by the U.S. National Marine Fisheries Service (NMFS) showed that its population had dropped to 15–20% of 1970s levels.” (source)

Beautiful animals, so tragic they are endangered.
