Sei and Bryde's whale look very much alike with only a few differences. Both species are slim and streamlined, since they are slim and have little blubber they are not often hunted. The only major difference is that the sei whale has one ridge from the tip of the snout to the blowholes, while the bryde's whale has three. Both the sei and bryde's whale have a bluish-gray body with white on the underside. The side fin are very short and pointed at the tips. Sei and bryde's are both baleen whales. Weight at birth in both species is 2000 pounds. Gestation period last about 11 1/2 -12 months and calves nurse for about 6 months. Both species are usually found in small groups of 2 or 3 but neither goes into the polar ice regions. Sei whales are found near the antarctic while bryde's are found in tropical waters. Both are fast swimmers moving up to 34.5mph.
Orca whales color are a black and white and has a saddal patch behind the dorsal fin. They are apart of the dolphin family and migrate in all oceans according to availability for food. They can weigh 8-9 tons and calves weigh up to 400 pounds. They feed on sealions, small whales, sharks and fish. Mothers are very protective of their young and can have calves every two years. Orcas usually come in pods travelling from hemisphere to hemisphere.

What would happen if all of the world's oceans dried up???
If all the world's oceans dried up we would have very high temperatures which would cause pretty much all of the animals that call it home to become very dehydrated and eventually die. Marine animals are one of our very important food sources and without them I think all the sea food lovers would go crazy. A lot of the trees and plants would die because of there not being any rain due to no water evaporating within the clouds. If there were no clouds then it would allow more sun to come through and burn hotter than it does now and would cause many other things to die as well. Humans would have a hard time surviving because of there being no water in our atmosphere and would also become very dehydrated. If all the oceans dried up and these things did actually happen the earth would pretty much die itself and no longer exist.
