There are two types of whales, toothed whales (Odontoceti) and baleen whales (Mysticeti). Toothed whales are predators that use their teeth to catch squid, fish, marine mammals, etc. Baleen whales have a sieve-like structure called baleen that catches huge amounts of tiny krill for nourishment and as a food source. They are also generally larger than toothed whales; and there are 10 species of baleen whales. Different species of whales vary drastically in terms of both size and weight. Baleen whales in the Mysticeti suborder are generally larger than those of the Odontoceti suborder. The Mysticeti group includes the blue whale the largest animal ever to live on the planet. The species can be up to 100 ft long (30m), and weigh as much as 150 tons (136 metric tons)—approximately 300,000 lbs. The sperm whale is the largest toothed-whale, reaching up to 70 ft (21m) in length and 59 tons (54 metric tons) in weight. The smallest baleen whale is the pygmy right, which averages a length of only 20 ft and a weight of 4 tons (6m/3.6 metric tons).
Whales resemble fish because of their fins and hydrodynamic bodies, but have far more in common anatomically with other mammals. Whales have very distinct characteristics and features like their diet, habitat, lifespan, and breeding and social structure.

opportunity to rapidly evolve and become very prosperous. Within Mammalia one order in particular, Cetacea, shows widespread adaptation and diversification. Cetacea includes all whales, dolphins, and porpoises. These once terrestrial species have made adaptations that allow for their current lifestyle. They have become highly modified for living in aquatic niches. Several key adaptations are conducive to Cetacea. Specifically, the forelimbs have modified into flippers, the pectoral girdle is reduced and…
SUMMARY Based on economics, science and ethics, Australia’s support for whale conservation is well known, ensuring that the global debate about the future of whales, dolphins and porpoises (cetaceans) are informed by the latest information. The progress report Conservation and Values Global Cetacean Snapshot was released on 14 June 2008 before the 60th annual meeting of the International Whaling Commission. The Global Cetacean Summary Report follows on by presenting the most current information on…
The order Cetacea includes the marine mammals known as dolphins, whales, and porpoises. The sub-orders include; Mysticeti, Odontoceti, and Archaeoceti. The Archaeoceti are ancient, extinct whales. Cetus is Latin and means "whale". its original meaning, "large sea animal", was too general. Some Cetacean species are highly intelligent and scientific movements have been made to classify them as "non-human persons." Cetology is the branch of marine science that deals with the study of cetaceans.…
As you approach the aquarium from the parking lot, there is a large whale fountain that is your starting point. Throughout the aquarium, keep your eyes open for animal adaptations for defense/protection Within Class Mammalia of the Animal Kingdom, whales fall into the Order Cetacea. Whales are further divided into two suborders: Odontoceti which includes toothed whales such as sperm whales, killer whales and dolphins, and Mysticeti, including baleen whales, which strain food from ocean waters through comblike baleen bristles…
living out of the pouch but returning to nurse.” (Myers, 2001, para. 6) A kangaroo does have hair and does produce milk for its offspring. Dolphins are also considered mammals and are under the classification of Cetacea. Porpoises and whales are also under this classification. Cetacea are aquatic animals. Some of the characteristics of the cetacean mammals are streamlined body shape, no external claws, external nares (blowhole) on the top of the head, internal reproductive organs. They also have…
SALT WATER Introduction: Salt water refers to water that contains dissolved salts, known as saline water or seawater, water from oceans or seas. It is a home to varieties of aquatic animals, for example, fishes and snails. Some of these animals find it difficult to live in fresh water. If salt water animals go to live in fresh water they can not adapt the environment led to die to them. This essay aims to discuss the importance of salt water and the sub- types namely ocean, sea, and coral reefs…
