This is an organism that has two identical alleles for the same genetic trait. Hybrid This is the offspring of a genetic cross between parents with different traits. Incomplete Dominance This is a trait that is a blend of the dominant and recessive gene; inheritance pattern where the phenotype of a heterozygote is intermediate between those of the two homozygotes; neither allele of the pair is dominant but combine and display a new trait.
The killer whale (Orcinus orca), also referred to as the orca whale or orca, and less commonly as the blackfish or grampus, is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member.Killer whales are found in all oceans, from Arctic and Antarctic regions to tropical seas.Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals like pinnipeds, and even large whales.ild killer whales are not considered a threat to humans, but there have been cases of captive orcas killing or injuring their handlers at marine theme parks. Killer whales feature strongly in the mythologies of indigenous cultures, with their reputation ranging from being the souls of humans to merciless killers.
Orcas feed on a wide variety of prey, from small schooling fish to large baleen whales. These cetaceans are powerful predators, which are not intimidated by large, or bulky animals, and are known to be able to attack even sharks. In general, killer whales feed on a large variety of fish, cephalopods and marine mammals.The estimated number of species consumed worldwide by orcas is around 140. They usually prey on squids, octopus, seals, sea lions, sea otters, rays, dolphins, sharks, baleen whales and of course, bony fishes.his stun or kill the prey so killer whales can feed on them. If the victim is a marine mammal, the orcas have to hit them with the tail or throw them in the air. The procedure to catch large baleen whales, usually involves all the members of the herd, as baleen whales are not small or weak animals.
