Humpback whale breaching. Cetacean surfacing behaviour is a grouping of movement types that cetaceans make at the water's surface in addition to breathing. Cetaceans have developed and use surface behaviours for many functions such as display, feeding and communication.
A beaked whale is any of at least 22 species of whale in the family Ziphiidae. Several species have only been described in the last two decades. Six genera have been identified. They possess a unique feeding mechanism among cetaceans known as suction feeding. They are characterized by having a lower jaw that extends at least to the tip of the ...

Humpback whales can measure 60 feet and weigh 40 tons, so when they breach nearly free of the surface their splashdowns are loud and spectacular. Watch: Breaching humpback whale makes boat ...
Little is known about the feeding behavior of Rice's whales, but data from a tagged individual revealed a diel vertical diving pattern, in which the whale spends most of the day feeding at or near the seafloor at depths of up to 271 meters (889 ft) and night at the surface. The whale's diet remains unknown, but lanternfish and hatchetfish are ...
The first study resulting from that work, published in the journal Animal Behaviour in July, focused on variations in the whales’ foraging behavior depending on their size and habitats.
Cetacean stranding, commonly known as beaching, is a phenomenon in which whales and dolphins strand themselves on land, usually on a beach. Beached whales often die due to dehydration, collapsing under their own weight, or drowning when high tide covers the blowhole. [1] Cetacean stranding has occurred since before recorded history. [2]
