Whales

Whaling affects people because it leads to an imbalance in the marine ecosystem. This means that other parts of marine life affected, which affects the quality of water, and the presence of fish for human consumption.

We've been studying high school biology. It seems that homotroph is a synonym for autotroph (basically, a producer, or an organism that makes its own food through photosynthesis). Therefore, a red panda is a heterotroph (which eats food rather than makes its own food).

commensalism == the barnacle living on the whales back gains safety and protection where as the whales does not either gain or lose anything from the relationship

Yes whales can stay under water for more than an hour, unless they are still babies then they need to have oxygen sooner.

People don't know for sure how often some whales breed. Some whales, like orcas and humpbacks, breed once every year or two, but nobody knows for sure about some, like blue whales.

The biggest thing is a Grapefruit. A blue whale's throat is about the size of a small plate - a blue whale, the largest mammal on earth, cannot swallow ships, buses, or gaint squid. they feed on krill. However, some smaller whales and orcas feed on (but still could not swallow whole) squid.

One way to stop it is by stopping poachers from hunting them.

No, "frog MAN", that is to say that is relative to an human and an animal, but no totally of one of them

Yes. The blue water takes in large amounts of water and krill into it's mouth and pushes out the water through filters, also called baleen, in it's mouth, leaving the krill, or plankton behind, which the whale then swallows. It's easier for the whale to swallow the krill, if it does not have to swallow a lot of water with it.

A new born blue whale is only 7 metres long and weighs 2700 kg. In the first 7 months after its birth, it gains 90 kg every 24 hours, until its full grown weight of 182 tons and 33 metres long.

A young humpback (calf) would fear orca, the main predator of the calves. Orca grow to over 30 feet and are quite the ambitious hunter, seen taking grey whale calves with some planning and quick execution. They love to eat the tongues! Adult humpbacks have very large and heavy tails (flukes), which are their main weapons, and they use them efficiently, smacking the water or perhaps attempting to hit any predator (including sharks in breeding grounds) coming close to them or their calves.

Whaling is the main reason. When it was first started, whale numbers were pretty high. Now however, whaling has gotten more serious, and whalers only use the meat off the whale. To add to this, whales have a low recovery rate, and so they reproduce very slowly. Within a century, whales will be extinct if whalers don't stop now. They are beautiful creatures and don't deserve the painful death they get.

Juvenile fish are called fry or fingerlings.

From the Related Link below: "A whale's smooth skin is an adaptation for swimming, and whales lose their hair before they are born. A newborn calf sometimes has a few sparse hairs around the rostrum."

So they do qualify as mammals, because they have SOME hair at SOME point in their lives.

All whales have hair they are mammals. All mammals have hair

Unfortunately people are breaking the law when they go whaling (except for native americans, who are allowed to do it so they can eat, they don't waste a thing on it) they are hunted for a oil called spermacetii.

Very, very sharp.

Bats, dolphins, Whales, shrews, flying squirrels use echolocation.

Initially, it was because of certain products such as whale oil was rare and so commonly used so when whale oil gets lower than demand then the prices goes up which drives further whaling. Countries like Norway and Japan would say that it was cultural so whale meat is consumed in certain countries like Japan, so there is a demand for cultural purpose of whale meat and with the ban on commercial whaling, it gets harder each year. What drives whaling as well today is that certain countries rely on it as a main food source of protein and has more protein compare to fish, so this increases the profit when number of whales decrease or when the annual catch decreases.

They live in the Arctic Ocean. So basically Northern North America, Northern Asia, and Europe.

Unknown, but possible. The bull shark, possibly a more dangerous predator than the Great White, can thrive in either salt water or fresh water, due to a unique physiology.

It has been known to move upstream in fresh water more than 2000 miles.
