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] .

Orcinis Orca. They’re commonly known as the Killer whale. But the Orca isn’t actually a whale: it’s in the dolphin family. And while it shares a lot of the same characteristics of dolphins, the Orca has some unique features that are all its own, like its camouflage coloring.

Sep 5, 2020 · There are 2 distinct types of blow holes, 1 blow hole or 2 blowholes. The one blowhole looks kind of like a donut and the 2 blowhole looks kind of like a heart. Whales that have teeth are going to have a single hole, where as a whale that has baleen is going to have 2 holes.

Jan 14, 2025 · The killer whale, also known as orca, is the ocean’s top predator. It is the largest member of the Delphinidae family, or dolphins. Members of this family include all dolphin species, as well as other larger species, such as long-finned pilot whales and short-finned pilot whales , whose common names also contain "whale" instead of "dolphin."

Jun 21, 2021 · Whereas humans breathe through their nose and mouth, whales have a blowhole on the top of their head—or two in the case of baleen whales. This is “like a nostril,” says Cunningham. While it’s not...

As whale watchers, you will observe orcas (killer whales) demonstrating many different Instantaneous and Prolonged maneuvers or behaviors. The physical actions described or shown below (or both) include the behavior name, what happens, and in some instances, explain why.

Orcas, also known as killer whales, are the largest of the dolphins. Like other odontocetes or toothed whales, they have one blowhole and are able to use echolocation, which is similar to SONAR, to navigate and locate prey.

Blowholes are modified nostrils, and whales use them to breathe air. The whale’s mouth and esophagus are completely separate from its blowhole and airway, so Nemo’s friends would find no escape there, and the spray that whales spout isn’t water.

Orcas, or killer whales, are the largest member of the dolphin family, reaching a length of 23 to 26 feet and weighing four to eight tons. Seeing orcas attack large whales, eighteenth century Basque whalers called the predator “ballena assasina” meaning, “whale killer.”

Blowholes are covered by muscular flaps that keep water from entering them when the whale is under water. In the relaxed state, the flap covers the blowhole. A blowhole leads to the whale's trachea and then to its lungs. Unlike us, whales cannot breathe through their mouth; they only breathe throught their blowholes.
