body parts
= = A whale has a few body parts it has dorsal fin which is on the top on a males body. The fin is more up right than the females the females have it more curved in.It also has an ear just like us humans, it has a blowhole that shoots water out, the blowhole is always on top of the whale and it uses it to breath. It also has an eye and just like us they use it to see. They also have a flipper they use the flipper to swim they move there fliper in a circuler rotation so they could swim. There is the fluke and the median notch wich they also use for swimming they move it up and down to push themselves foward.

= = killer whales are usally grow to be about 27-33 feet long they are like this mostly because of what they eat and ther ansisters.An averaged size whale i s about 8,000-12,000 pounds sometimes even more this is because again because of there food habit. The male is usually larger than the female. Just lik = = e us the males does grow bigger on most ocassions.

new born
==

killer whales usually breed in the winter u = = p to the early spring. They are usually in the surface on the water when breeding or in warm waters.a killer whales is usually pregnate for 16-17 months.a calf (baby whale) is born tails first this is normal for whales. they usually give labor near or in the surface usually between october and march.the new born naturally swim up to the surface to take its first breath within the first ten seconds.of course it has the mothers helps, the mother helps by pushing the calf with her fin. within the 30 minutes of birth the calf learns how to swim.the new born is about 6-8 feet long. when its born it wheighs 400 pounds. For a whale to have twin its very very wierd and unusual ther is almost always one calf. the baby is nurtured by the mothers milk.the calf is with the mother for one year or loger.The femal is an adult at 6-10 years, and the male is an adult from 12-16 years old.

food
killer whales usually eat fish, squid, and marine mammals. This is what they usually find in killer whales stomach. The wierd thing is that they also fined remains of other killer whales in there stomach. They think its because they eat the remanings of animals. In the Antarctic killer whales eat about 67% fishes, 27% marine mammals and 6% squids.and in the Bering Sea near Alaska, they eat about 65% fishes, 20% squids, and 15% marine mammals. Transient groups mainly eat marine mammales and fish once in a while. Adult killer whales eat about about 3% or 4% of their own body whieght per day. Calfs eat abput 10% of their body whieght during growth periodes. Killer whales often hunt for preys in groups, they usually work together to encircle there prey. Also when they attack there pray the pac tends to do it from different angles.

habitat
They can adapt in all waters but are mostly in the artic,antartica, and in cold waters. They can also be found in the eastern cost of the united states.Aside from cold areas they can also be foound in warm waters such as hawaii,austeralia, golf of mexico ect.. Whats wierd is that they have been seen in fresh waters and rivers. They usually dont like to be lower than 200 m deep. Most killer whales migrate when fish or prey are migrating.Because of the fact that they are spred basicly all over the world they are not sure what the population is.

PAGE 6:

activities
killer whales usually just hunt, travel,rest and socialize.Hunting is what whales do most, most pods help each other to get the prey. They travel very often they often travel from one good feeding place to another.Members of the group usually stop after hunting.They usually slow down a little or sometimes the hole pod stops and rests from less than 1 hour to more than 7 hours.But they dont really rest that often

senses & communication
whales usually communicate by squeeking and screaming Killer whales have acute hearing and also acute vision in and out of the water. They could discriminate objects by making high frequency sounds, sound waves, and listening for ecoes
