Why do orcas have an eyespot?
Killer whale eyes are only about the size of a cow’s eye. They are dwarfed by the huge eyespot or false eye above and behind the real eyes. Eyespots also called eye patches, may have evolved to help whales identify each other, or to protect their real eyes from the attacks of sharks.
How do orcas camouflage?
Orcas are known for their long dorsal fin (the fin on the animal’s back) and black-and-white coloring. The black-and-white coloring helps to camouflage them by obscuring their outline in the water. Just behind the dorsal fin is a patch of gray called a “saddle” — because it looks like a riding saddle.
What adaptations do killer whales have?
Thick layer of blubber for warmth. Can swim very fast (up to 30mph) to catch prey. Use echolocation (bouncing sounds off objects) in order to locate their positions and for hunting prey. Have sharp teeth up to 10cm long, to rip apart and chew their prey.
How do orcas use echolocation?
The whales hunt with echolocation, which is the use of sound waves and echoes to locate objects. When hunting, a killer whale sends out a series of clicks, called a click train, that spread through the water like a flashlight beam of sound. If the sound waves hit an object, echoes bounce back to the whale.
Why do orcas have white spots behind their eyes?
Sea creatures like killer whales are known to have eyes that look a lot similar to cows’ eyes. The white patches or splotches near either side of a killer whale’s head near their eyes are called eyespots or eye patches. These eye patches are just a normal coloration in their body.
Why do orcas have white patches?
Killer whales (orcas) have a very distinctive pattern of black and white, which serves as a form of camouflage from their prey.

What makes the killer whale unique?
They’re immediately recognizable by their distinctive black-and-white coloring. Smart and social, orcas make a wide variety of communicative sounds, and each pod has distinctive noises that its members will recognize even at a distance.
Why are killer whales effective predators?
The size of the orca whale guarantees its spot at the top of the food chain. In large pods, orcas make formidable predators. Orca whales will also use their powerful tails to stun prey. The orca’s sharp eyesight and acute sense of hearing also help the whale navigate through the water, locate prey and avoid danger.
How does echolocation work whales?
Dolphins and whales use echolocation by bouncing high-pitched clicking sounds off underwater objects, similar to shouting and listening for echoes. The sounds are made by squeezing air through nasal passages near the blowhole.
