What is Mysticeti referring to?
Definition of Mysticeti
: a suborder of Cetacea consisting of the whalebone whales — compare odontoceti.
How many families are in Odontoceti?
Suborder Odontoceti comprises 10 families, for a total of 72 species.
Why did Livyatan go extinct?
Livyatan-like sperm whales became extinct by the early Pliocene likely due to a cooling trend causing baleen whales to increase in size and decrease in diversity, becoming coextinct with the smaller whales they fed on.
Which two groups are classified under Mysticeti?
Cetus from the Latin meaning whale. Cetaceans are generally placed into two distinct sub-orders the Mysticeti (whales with baleen) and Odontoceti (toothed whales.)
How many families does Mysticeti have?
Mysticeti have two blowholes, whereas toothed cetaceans (suborder Odontoceti) have only one blowhole. Females are larger than males although sexual dimorphism is less marked as it is in most odontocetes, for which males are bigger than females. Suborder Mysticeti comprises 4 families, for a total of 15 species.
What’s the difference between Mysticeti and Odontoceti?
Whales in the Mysticeti suborder have baleen plates that serve as a filter-feeding system, while marine mammals in the Odontoceti suborder—which includes dolphins and porpoises as well as whales—have teeth.
What are the 3 subgroups of odontocetes?
The order Cetacea is divided into three subgroups: The Odontoceti or “toothed whales,” including 65 or more living species of dolphins, porpoises and whales (sperm whales, belugas, narwhals and beaked whales). All of these species have teeth.
How can you tell the differences between Odontoceti and Mysticeti?
Mysticeti have two blowholes, whereas toothed cetaceans (suborder Odontoceti) have only one blowhole. Females are larger than males although sexual dimorphism is less marked as it is in most odontocetes, for which males are bigger than females.
Is Cetacea a family?
Cetaceans (order Cetacea) are an entirely aquatic order of mammals comprising the whales, the dolphins, and the porpoises. The ancient Greeks recognized that cetaceans breathe air, give birth to live young, produce milk, and have hair—all features of mammals.
Is Leviathan bigger than Megalodon?
After the dinosaurs went extinct, 65 million years ago, the biggest animals on earth were confined to the world’s oceans—as witness the 50-foot-long, 50-ton prehistoric sperm whale Leviathan (also known as Livyatan) and the 50-foot-long, 50-ton Megalodon, by far the biggest shark that ever lived.
Who can defeat Megalodon?
There are many animals that could beat megalodon. Some say megalodon ate Livyatan but it was an ambush predator and Livyatan might have eaten it too. The modern sperm whale, fin whale, blue whale, Sei whale, Triassic kraken, pliosaurus and colossal squid could all beat the megalodon.
What is the name of suborder 2?

What whale is the biggest?
Blue whaleWhale / Biggest
The Antarctic blue whale (Balaenoptera musculus ssp. Intermedia) is the biggest animal on the planet, weighing up to 400,000 pounds (approximately 33 elephants) and reaching up to 98 feet in length.
What is the main difference between Odontocetes and baleen whale?
There are two types of whale; baleen and toothed. The key difference between them is the way they feed and what they have inside their mouth. Baleen whales have baleen plates, or sheets, which sieve prey from seawater. Toothed whales have teeth and they actively hunt fish, squid and other sea creatures.
What are the differences between mysticetes and odontocetes?
Generally, odontocetes are smaller than mysticetes. Odontocetes are also more social than mysticetes, and live together in family groups called pods. While all cetaceans have two nostrils, odontocetes have a muscular flap covering one nostril. Thus, odontocetes only have one blowhole.
Is Cetacea a suborder?
Introduction. Members of the suborder Cetacea, like the sirenians, are fully aquatic large mammals. The suborder is divided into two parvorders: Mysticeti (baleen whales) and Odontoceti (toothed whales). Whales inhabit the temperate and polar oceanic zones.

Who is the king of the ocean?
Great white sharks, to be exact. But the true ruler of the sea is the killer whale. Killer whales are apex predators, which means they have no natural predators. They hunt in packs, much like wolves, which are also at the top of their food chain.
What hunted megalodon?
Mature megalodons likely did not have any predators, but newly birthed and juvenile individuals may have been vulnerable to other large predatory sharks, such as great hammerhead sharks (Sphyrna mokarran), whose ranges and nurseries are thought to have overlapped with those of megalodon from the end of the Miocene and …
Is the killer whale A whale?
