Aquatic Mammals
This section is for questions about those mammals that live most, if not all of their lives in the water. With specially adapted breathing abilities, these swimmers are some of the most intelligent creatures known.

What kind of sea creatures are omnivores?
The word 'omnivores' just means a creature that eats just about anything; i.e humans are omnivores unless you are vegetarian or similar.
Sea lions move by using their powerful front flippers to "walk" or crawl on land and by using a combination of their front and hind flippers to swim in the water. They are very agile and versatile swimmers, able to reach high speeds and perform quick maneuvers to catch prey or evade predators. On land, they are also quite agile and can move surprisingly fast despite their large size.
How many seals are killed in Canada?
In the past five years alone, more than one million seals have been slaughtered in the commercial seal hunt in Canada. The actual number of seals killed is likely higher than that, though, because many seals are shot at and injured in the course of the hunt, and many of these animals slip into the water, where they die slowly and are not counted or recovered.
What is a whales average lifespan?
The average lifespan varies by each different species of whale. For example, a bowhead whale can live to 130 years old.Compare to gray whales who can only live 1/3 of that.
What is the life expectancy of a minke whale?
This depends because many die before their expected life span. Typically, the live until they are between 40 and 50 years old. However, many die earlier because of either orcas or humans killing them.
What the name of a scientist who studies sea creatures?
Marine biologist.
Actually, a Marine Biologist is someone who studies marine organisms (plants, oceans, and animals), but someone who studies MAINLY marine mammals is a marine mammalogist.
Dolphins are in the group of marine mammals called cetaceans, specifically within the family Delphinidae. Within this family, there are different genera and species of dolphins, such as bottlenose dolphins, killer whales, and spinner dolphins.
Is a whale in the Phylum Chordata?
Yes, whales are chordates. They are also vertebrates, meaning they have a skeletal system.
However, there is more to it than that, especially given that there are two invertebrate chordate groups - Urochordata (tunicates) and Cephalachordata (lancelets) - whose backbone is not in the form of actual vertebrae.
As Chordates (or members of the phylum Chordata), whales share the following characteristics:
- dorsal nerve cord which is a bundle of nerve fibres which runs down the back. It connects the brain with the lateral muscles and other organs.
- notochordwhich is a cartilaginous rod running underneath, and supporting, the nerve cord - in the case of the whale, a spine.
- post-anal tail - an extension of the body past the anal opening. (This feature is not always present in some adult Chordates such as frogs and humans, but it is present in the whale.)
- Pharyngeal pouches - Chordates, at some stage of their life, have pharyngeal grooves and pouches that develop into other essential parts of their anatomy.
Whales are a diverse group of marine mammals belonging to the order Cetacea. There are many different species of whales, including the blue whale, humpback whale, sperm whale, and killer whale.
What is a whales binomial name?
The binomial name for a whale is Balaenoptera musculus, which refers to the species of blue whale.
What is the scientific name for toothed whales?
The scientific name for toothed whales is Odontoceti.
What is a zoological name for a whale?
Balaenoptera
Whale is the common name for marine mammals of the order Cetacea. The suborders are Odontoceti (toothed whales) and Mysticeti (baleen whales).
What is the scientific name for the California sea lion?
Taxonomy Together with the fur seal, they comprise the Otariidae family, collectively known as eared seals. Until recently, sea lions were grouped under a single subfamily called Otariinae to distinguish them from the fur seals Arcocephalinae, based on the most prominent common feature between all species, namely the lack of dense underfur characteristic of the latter. Recent genetic evidence, however, strongly suggests that the Callorhinus, the genus of the Northern fur seal is more closely related to some sea lion species than to the fur seal genus Arctocephalus. Therefore the fur seal/sealion subfamily distinction has been largely eliminated. Nonetheless, all sea lions have certain features in common, in particular the coarse, short fur, greater bulk and larger prey than fur seals.
What is the scientific name for harbor seals?
The scientific name for harbor seals is Phoca vitulina.
What is a scientific name for a steller seal?
The scientific name for a Steller sea lion is Eumetopias jubatus.
It is practically beyond argument that the (Little Yellow Pills) in the popular song Mother"s little Helper)- by the Rolling stones, refer to Valium in 5MG doses. What a Drag it is coming down..... Nothing to do with science fiction, but something akin to Drug abuse- a real Dagger of the Mind!
How long do dolphins live for in the wild?
Dolphins in the wild can live for about 40 to about 70 years. The smaller dolphins like the Bottlenose dolphins live about 40 years while the orcas live closer to 70 years.
What physiology does a whale use to jump out of the water?
The behaviour is called breaching. It's not just Sperm Whales that do this, whales in general as well as rays and some sharks do this.
Why? Scientists are studying the behaviour and aren't sure why they do this. One theory is it's a way of communicating to one another. Think of it as a long distance communication system. Another theory is that it's a method of removing barnacles and other irritations from their skin.
