In cetology, the study of whales and other cetaceans, a blowhole is the hole (or spiracle) at the top of the head through which the animal breathes air. In baleen whales , these are in pairs. It is homologous with the nostril of other mammals , and evolved via gradual movement of the nostrils to the top of the head. [ 1 ]
Blowhole may refer to: Blowhole (anatomy), the hole at the top of a whale's or other cetacean's head; Blowhole (geology), a hole at the inland end of a sea cave Kiama Blowhole in Kiama, Australia; The Blow Hole, a marine passage between Minstrel and East Cracroft Islands in the Central Coast of British Columbia, Canada
The melon is structurally part of the nasal apparatus and comprises most of the mass tissue between the blowhole and the tip of the snout. The function of the melon is not completely understood, but scientists believe it is a bioacoustic component, providing a means of focusing sounds used in echolocation and creating a similarity between characteristics of its tissue and the surrounding water ...
A blowhole system always contains three main features: a catchment entrance, a compression cavern and an expelling port. The arrangement, angle and size of these three features determine the force of the air to water ratio that is ejected from the port. [6] The blowhole feature tends to occur in the most distal section of a littoral cave. As ...
Porpoises, like other odontocetes, possess only one blowhole. [12] Breathing involves expelling stale air from the blowhole, forming an upward, steamy spout, followed by inhaling fresh air into the lungs. [12] [16] All porpoises have a thick layer of blubber. This blubber can help with insulation from the harsh underwater climate, protection to ...
The lower jaw is always relatively small and thin relative to the upper jaw. The nasal bones of these whales are distinctly asymmetrical, with the blowhole being located on the left side of the head; in the sperm whale, this is near the top of the head, while on the kogiids it is further forward. All species have a large number of similar, and ...
See images of Giada De Laurentiis through the years: "I do nibble!" she admitted to Health. "I always have a ton of precut mixed fruit in my fridge, and bowls of mixed nuts that I've toasted."
In a typical mammalian body such as the human body, the external body orifices are: . The nostrils, for breathing and the associated sense of smell; The mouth, for eating, drinking, breathing, and vocalizations such as speech
