no,though rarely a narwhal might use its horn for combat, though the horn is really just used for breaking ice
i would answer it if i could but it doesnt really make much sense.what do you mean?
I have heard from some people that it does but not in all cases. One guy claimed to use it on 3 cars. 2 were fixed, 1 wasn't. I heard it will also gunk up things like water pumps over time so would only use if you are going to junk the car otherwise.
Yes, they do. Whales are marine mammals, and all mammals are vertebrates.
It was found in Pakistan; hence the name Indus. But it is only a fossil. Don't get mistaken as an extant species.
Indus Valley Civilization in South Asia 8000- 1300 B.C. is one of oldest civilizations. The amulets tablets seals and other objects are preserved at many places. The main corpus of writing dated from the Indus Civilization is in the form of some two thousand inscribed seals and tablets in good legible conditions in about 1000 settlements of varying sizes. The seals and tablets from Matured Harappan Civilization 1900-1300 B.C. are actual and real with readable scripts preserved at many sites and at many Museums in Pakistan India and other countries.
What are some semi aquatic animals in Australia?
There are no native underwater freshwater mammals in Australia. The platypus and native water-rat are both semi-aquatic, meaning they actually live on land, not underwater.
There are, of course, many species of fish. In addition, there are some underwater marine mammals native to Australia (but not necessarily found exclusively in Australian waters), which include:
- dugong
- dolphins - various species
- whales - various species such as Southern Right whale, Humpback and Minke
Then there are the seals - various species such as the Australian Fur seal, Leopard seal, Weddells seal - and the Australian sea lion.
Are seals the fattest fish in the world?
No. A Seal is not a fish.
a piglifiteteretr is a fish compared to camal
Yes, his name was Hoover. Look him up, Hoover the famous seal. Here's a link to the information on Hoover http://en.wikipedia.org/wiki/Hoover_(seal) there also was a seal named Andre http://en.wikipedia.org/wiki/Andre_(film) (it's based off of a book called A Seal Called Andre which was based on a true story) Hope this helps
What do whales breathe out of?
Whales breathe in and out of their blowhole. They are unable to breathe through their mouth because the trachea is not attached to the throat.
Manatees are marine mammals. The most well known type in the States is the Florida manatee. Florida manatees are endangered for a variety of natural and human causes. Manatees are very sensitive to cold water temperatures, and will perish if they remain in waters below about 68 degrees for too long. This is because they do not have a thick layer of blubber like dolphins or whales. In addition, red tide is a natural algal bloom that produces toxins which effect the central nervous system; these are fatal to many marine organisms, including the manatee. Human activities also result in manatee deaths. It is not uncommon for manatees to be struck by boats, and either the propeller or the hull can cause fatal injuries. In addition, crab traps and fishing line can ensnare the curious manatees, making it impossible for them to ascend to the surface for air. Though they have large lungs, manatees can only hold their breath for about twenty minutes, and if they are exerting a lot of energy, that time decreases substantially. Occasionally, manatees are trapped in canal locks and flood gates. Luckily for the manatee, they have no natural predators. Their large size seems to deter animals like alligators and sharks. Also, manatee populations are slow to recover after a blow to their numbers. The gestation period for manatees is about 13 months, and it is rare for manatee mothers to give birth to more than one calf at a time. Once the calf is born, it remains with its mother for about two years, making each calf about a three year investment.
Additional Information: There is also the, Amazonian Manatee, the West Indian Manatee, and the Dugong all with a status of "endangered", as well as the West African Manatee, listed with a status of "threatened" according to the U.S. Fish and Wildlife Service, List of Endangered Species. All of the Manatee species listed above are listed by the International Union for Conservation of Nature, or the IUCN Red List as well. While they are all listed, the status is different for three of the species from one list to the other. The Red List has them all listed with a status of "vulnerable", and the South American Manatee and the West Indian Manatee each has a population trend posted as "decreasing", while the Dugong, and the Amazonian Manatee each has a population trend posted as "unknown".

Goldfish release growth-inhibiting hormones into the water they live in: the more goldfish in a smaller space, the less likely they are to grow. For instance, if I have a common goldfish in a 5 gallon tank, it will grow to about the same size if I had 6 of the same fish in a 30 gallon tank. But leave that fish alone in a 30 gallon tank, and it will grow larger. This is why pond goldfish grow bigger.
But goldfish won't grow at all in seawater; they aren't saltwater fish.
