Eubalaena+Australis

Also known as the Southern Right Whale.

The Eubalaena Australis is most commonly found in the Atlantic Ocean. The range of latitude for the Eubalaena Australis in the Atlantic Ocean is 90 degrees south to about 50 degrees south. The salinity is about 34.8 PPT to 33.5 PPT and below. The temperature of the water of the Atlantic Ocean the Eubalaena Australis lives in ranges from 6 degrees celcius to -2 degrees celcius. __Endangered Species Act:__ Eubalaena Australis populations are showing a slow increase since they began to be protected in 1935. The goal is to protect them while they are breeding and reproducing off the coast of South Brazil. Members of the program research the status of population, and talk to the public to spread the idea of protecting the enviorment. __Habitat:__ The Eubalaena Australis usually avoids warm water near the equator and usually remain near islands and other large land masses. __Location of ecosystem:__ The Eubalaena Australis is only found in the southern hemisphere, usually between 30 and 50 degrees south, in sub-Antartic waters. __Physical Habitat Features:__ __Migration Patterns:__ The Eubalaena Australis migrate to the southern latitudes of the cooler waters during the summer months where plankton groups are greater, and migrate north during winter and spring. __Survival Trends:__ The population of the Eubalaena Australis is slowly increasing due the their official protection by the government. They were interrupted by human impact when they were running into big ships and getting tangled in large fish nets. It was decided that the population needed to be put under servailance and researched further. Now restrictions have been set and the progress is showing. __Physical Description:__ The Eubalaena Australis is recognized mostly by it's dark color and white callosities found on and around their heads. Callosities are outgrowths of tough skin. They are usually used in identifying individual whales because each one has a different patter of collosities on their skin, similar to fingerprints in humans. - **Mass:** 36000 to 73000 kg; avg. 49000 kg (79200 to 160600 lbs; avg. 107800 lbs) - **Length:** 16 to 18 m (52.48 to 59.04 ft) __Reproduction:__ The Eubalaena Australis can have up to seven males per female. Reproduction lasts up to about an hour or two and then afterwards, the two whales seperate. So far, scientists have discovered that the individual male whales do not get jealous or angry when they mate with the same female which is unusual for mammals. They reach reproductive maturity at about ten years old. The babies are born weighing 1000-1500 kg and are five to six meters long. They grow at a rate of 3 cm per day. __Anatomy and Physiology:__ - The Eubalaena Australis is between 16 and 18 meters long at maturity. - Males are slightly shorter than females. - Does not have any dorsal fins. - He has an enormous head (approximately 1/3 the body length). - They also do not have the grooved throat that other whales of it's type have making it extremely unique. - The flippers are broad and very short. - They have a well developed skin for deep ocean swimming unlike most of it's similar species. - They also do not have fat on their skin. - They also have nostrils in their blowhole and the shape of it reduces moisture. - They have out-growths of rough patches of skin on their heads. __Food Chain__: These whales eat mostly plankton. Nothing eats these whales. __Economic Importance of species__: Even though they are rarely found stranded along beaches, sometimes these whales do cause harm to themselves and even to humans. They have accidentially come in contact with large vessels and gotten tangled in fishing gear cause the ships to take different routes and a big loss of equipment.
 * - __Geologic Processes:__** Sea floor spreading - The lengths of many 20-to-100-kilometer-long spreading segments have changed surprisingly fast, at a rate close to that of seafloor spreading itself (about 1 centimeter, 0.4 inch, per year).
 * - __Population:__** It is estimated that there are 3,000 to 4,000 currently surviving in the southern hemisphere currently.

__**Questions:**__ How does the Eubalaena Australis affect humans economically? How does the Eubalaena Australis' anatomy differ from most other whale species? When the Eubalaena Australis gives birth, what kind of relationship does it have with it's young?
