Adaptations
The orcas' skin is black on the top and white on the bottom, with a white patch behind each eye.
The average length of an adult orca can reach 32 feet, with the tail accounting for about one-third of the body and the fin reaching about 6 feet. Orca teeth are used for grasping, tearing, and consuming prey. A body orca is about 2.2 to 2.6 meters long and weight about 160 to 175 kilograms, and looks similar to an adult orca.
The tail makes the orca even more special. It helps the orca swim and drive away animals that threaten the killer orca. It can also grab prey from the ice and make it fall into the sea.
The reason why orcas look like this is because the color of the sea is dark from above and light from below. The black and white combination of orcas make is difficult for creatures on land and under the sea to find it. The pointed teeth make it easier for it to eat prey. The long fin makes it more stable when swimming.
INTERESTING FACTS
There are more interesting facts about orcas, such as their ears. Orcas's ears are small holes behind the eyes. When in the deep sea areas, their ears can help their eyes find direction and judge whether there are obstacles ahead. Scientists have discovered that orcas can use their blowholes, which is when they surface to breath. And each orca has unique markings on its fins, similar to human fingerprints.
