Are orcas toothed whales?

The toothed-whale group also includes porpoises, dolphins (including orcas, also called killer whales), and the monodonts—narwhals and belugas. Beluga whales are odontocetes, or toothed whales. ... Toothed whales such as sperm whales hunt their prey one by one.

How many Odontocete species are there?

Learn About the Odontocete Species

There are currently 86 recognized species of whales, dolphins, and porpoises. Of these, 72 are Odontocetes or toothed whales.

How many toothed whales are there?

There are 76 toothed whale species altogether and they are grouped into ten families: the sperm whale; the dwarf and pygmy sperm whale; the beluga and narwhal; the beaked whales; the oceanic dolphins; the four river dolphins (each one is placed in a family of their own); and the porpoise family.

What is the largest toothed whale?

Unlike the other great whales on the endangered species list, the sperm whale is a toothed whale. It is the largest of the toothed whales—also called odontocetes—reaching a length of 60 feet in males and 40 feet in females.

Which toothed whales are not dolphins?

Orcas have a lot of characteristics in common with whales, but taxonomically, they're actually dolphins!

What is the difference between dolphin and porpoise?

The difference between a dolphin and a porpoise has to do with their appearance: dolphins have longer snouts, bigger mouths, more curved dorsal fins, and longer, leaner bodies than porpoises.

Can all cetaceans Echolocate?

Only some whales, dolphins, and porpoises (collectively known as cetaceans) can do this. Cetaceans are split into two groups, those with teeth and those with baleen. Baleen whales (mysticetes), including blue whales and humpback whales, filter ocean water for tiny crustaceans and fish and do not need to ecolocate.

Are toothed whales big?

Toothed whales range in size from the 4.5 ft (1.4 m) and 120 lb (54 kg) vaquita to the 20 m (66 ft) and 55 t (61-short-ton) sperm whale. Overall, they tend to be dwarfed by their relatives, the baleen whales (Mysticeti). Several species have sexual dimorphism, with the females being larger than the males.

What are the two basic groups of toothed whales?

The order Cetacea, that includes whales, dolphins, and porpoises is divided into two main groups: the toothed whales (Odontocetes) and the baleen or whalebone whales (Mysticetes). Toothed whales include dolphins, porpoises, as well as the large sperm and killer whales.

Are blue whales and humpback whales the same?

Are blue whales humpback whales? No. These are two separate species of whale. Humpbacks are smaller, bluer whales, and blue whales are significantly larger greyer whales.

Are there two types of whales?

There are two types of whales: toothed and baleen. Toothed whales, as the name suggests, have teeth, which are used to hunt and eat squid, fish, and seals. Toothed whales include sperm whales, as well as dolphins, porpoises, and orcas, among others.

What is the rarest species of whale?

Based on its scarcity, only two intact animals having been seen in the last 140 years, the spade-toothed whale is the world's rarest whale.

Why is it called spermaceti?

Spermaceti (from Greek sperma meaning "seed", and ceti, the genitive form of "whale") is a waxy substance found in the head cavities of the sperm whale (and, in smaller quantities, in the oils of other whales). Spermaceti is created in the spermaceti organ inside the whale's head.

What does a dolphin's teeth look like?

Most dolphins have equal-sized conical shaped teeth in both upper and lower jaws (porpoises' teeth are spade-shaped) perfect for grasping fish and squid. Like most mammals, newborn dolphin teeth are still embedded in the gums.

What whales have no teeth?

Whales Without Teeth

Baleen whales do not have teeth. Baleen whales have two blowholes, and they tend to be larger than toothed whales. Instead of teeth, whales in this group have special baleen plates with bristles that serve their dental needs.
