2. Why did I chose The Killers Whales? The biggest killer whales are members of the dolphin family, which exists in many parts of the world than probably any other ocean. Killer whales live in both open ocean and near the coast and more common in the cold, are more productive than in tropical waters. The color of killer whales is Black or deep brown with white spots on the eye, and the lower jaw to the belly. They are also marked with a weaker patch of grayish white color just below and behind the spine. Adult males usually attain lengths up to 9.8m. (up to 32 feet.), while mature females reach lengths of up to 8.5 m (up to 28 feet.). It's something totally awesome to know the size of these marine animals. The color and how they stay in groups. The most impressive thing is that killer whales have a triangular dorsal fin in the center of the back that can grow as high as 1.8 meters (5.9 feet) in the adult male, and one thing that surprises me are the fins of both sexes are large and oval, unlike any toothed whale. But for me to learn about them has been something that I like and I would like to continue knowing.

3. KILLER WHALES ACTIVITIES: Killer whales have a wide range of activities as they progress in their daily lives, I mean they are kept grabbing activities that are already accustomed to Asher, the activities of killer whales are groups of four categories: search for food, travel , Relaxation and socialization. Bone seeking food, travel everywhere, rest, and like to socialize with other marine animals. The collection is the most common, and it seems that killer whales are in search of food. Different eating patterns are evident in both residents and transients, depending on the type of prey. All members of a pod of killer whales bone all cooperate in finding food for them. A pod is a group of killer whales traveling together and hunt for food.

4. Killers Whales Senses & Communication: Killer whales can also be distinguished by the type of underwater communication, and the sounds they produce: screams, cries and shouts are used for communication within and between groups. Orca clans such as dolphins, can not be distinguished by their different dialects. That means that killer whales communicate using sounds different from each other marine animals can not differentiate because they are the same sounds. Killer whales have acute hearing and sharp vision, both in and out of water. that means that whales have the same characteristics and reactions both in and out of the water. They hear the same vision perfectly. Most impressive is that killer whales locate and discriminate objects by projecting high-frequency sound waves and listening to the echoes. Orcas by producing echolocation clicks and then receiving and interpreting the results of the resulting echo. Objects can be found listening to the noises or sounds.

5. KILLER WHALES BEHAVIOUR: Most studies have been carried out in killer whales live in small parts of the sea, on united, and their groups called pods. The size of a pod of residence varies from a minimum of 3 to a maximum of 50 people who tend to travel within specific ranges. This means that groups of killer whales are 3 to 4. The Killers whales live and travel in groups or pods organized along lines of maternal relationship. Studies of resident orcas have been able to identify killer whales travel in groups. Transients on the other hand often travel alone or in groups of 2 to 7 killer whales. Individuals, and their ranges of travel are unpredictable. travel constantly.

6. KILLER WHALES REPRODUTION: Sexual Maturity: Many details of a reproduction of killer whales are not known because it is difficult to study in the wild. What we do know is marine studies offered by zoos. Women however do not reach sexual maturity when they reach 4.6 to 4.9 m. about another 15 to 16 feet in about 6 to 10 years. Males reach it instead from 5.5 to 6.1 m (18-20 feet) at the age of 10 to 13 years. This means than Croesus too much too soon and can not have babies till they reach the age of 6 to 10years. In males, the growth of the dorsal fin is probably a secondary sexual characteristics. Maximum growth of the fin coincides with the onset of sexual maturity.  In places where men have habitats for whales mate successfully at the age of 8, but in nature, social factors influence reproduction in men. With the killer is the same for the need to be much older, bigger, and able to compete with other males. This means that males compete for female whale

7. KILLER WHALES FACTS: DISEASE: Orcas and other whales stomach ulcers, diseases skim, tumors, heart disease and respiratory disorders.  Hodgkin's disease has been on the orcas. Killer whales stranded demonstrated severe atherosclerosis of the coronary arteries.  The orcas are suffering from viruses, bacteria, and fungus infections. Abscess of the jaw, resulting from wear and exposure to dental pulp cavity is a common observation among orcas in the wild. That means that whales are too many viruses and developing it from Different ways in my opinion it's all because of the water contamination. PARASITES: Including worms, tapeworms and flukes, may affect the health of the killer whale. In most cases, only parasite infestations are unlikely to weaken the otherwise healthy animals, but can harm the animals that are already weakened by other diseases or injuries. This means that these parasites damage the whale if the whale is sick and weakens much more than it already is.
