Mesoplodon

Mesoplodon is a genus of beaked whales in the family Ziphiidae. Its species inhabit oceans worldwide and are distinguished by specialized teeth, often most prominent in adult males.

Ziphiidae: Ziphiidae is the family of toothed whales known as beaked whales, adapted for deep diving. Mesoplodon is one of the largest genera within this family.
Blainville's beaked whale: Blainville's beaked whale is a medium-sized beaked whale found in tropical and temperate oceans worldwide. Its strongly arched lower jaws and prominent teeth exemplify the genus's distinctive anatomy.
Deep diving: Deep diving is the behavior of descending far below the surface to forage or travel underwater. Mesoplodon species make long, deep dives while searching for prey.
Sonar: Sonar is a system that uses sound propagation underwater to detect objects or measure distance. Military sonar has been associated with mass strandings of some beaked whales.
Beaked whale: Beaked whales are a family of toothed whales characterized by elongated beaks and deep-diving habits. This broader group provides the anatomical and ecological context for Mesoplodon.
Sowerby's beaked whale: Sowerby's beaked whale is a North Atlantic beaked whale, first described from a specimen found in 1800. It is one of the earliest scientifically described Mesoplodon species.
Echolocation: Echolocation is the use of emitted sounds and returning echoes to detect objects and navigate. These toothed whales use biosonar to find prey in dark deep water.
Cetacean stranding: A cetacean stranding occurs when a whale, dolphin, or porpoise becomes stranded on shore or in shallow water. Strandings provide many of the few specimens available for studying Mesoplodon.
Toothed whale: Toothed whales are cetaceans that use teeth to seize prey and include dolphins, porpoises, and sperm whales. Mesoplodon belongs to this cetacean suborder, unlike baleen whales.
Gervais' beaked whale: Gervais' beaked whale is a beaked whale found mainly in the tropical and warm temperate Atlantic. Its Atlantic distribution contrasts with the broad ocean ranges of several congeners.
