strap-toothed whale

The strap-toothed beaked whale (Mesoplodon layardii), also known as Layard's beaked whale, is one of the largest members of the Mesoplodon genus, growing to 6.2 m (20 ft) in length and reaching up to 1,300 kg (2,900 lb). The common and scientific name was given in honor of Edgar Leopold Layard, the curator of the South African Museum, who prepared drawings of a skull and sent them to the British taxonomist John Edward Gray, who described the species in 1865. This species is known for its unique coloration pattern and long, curved teeth that arch over the upper jaw, ultimately restructuring gape. This species inhabits deep subantarctic waters of the southern hemisphere. Strap-toothed whales rely on echolocation clicks, surface at step angles, and tend to travel in small groups. Their diet consists mainly of aquatic squid and males and females hunt the same sized prey. Although not a target for whaling, threats like plastic ingestion, noise pollution, and climate change can be threatening to Mesoplodon layardii.
