Dolphins

Scientists reveal that Dolphins use sound in an unusual way. It’s called echo-location. A specialised fat filled organ called the melon behind the forehead emits focused vibrations of sound. The key to echo location is listening to the echoes of those sound waves as they come back. Dolphins pick up and amplify these returning waves with a cavity in their jaw before sending them on to the inner ear.They use echo location to hunt down and pinpoint their prey, even in darkness. Dolphins share this use of hearing with nocturnal animals like bats. This echo location is an extremely powerful sensory tool which allows the dolphins’ mind to build up a picture of the world.

Dogs

Dogs have an extremely powerful nose. They can smell, in parts per trillion and can sniff and find out anything that’s hidden. But, how can they do this?Each of their nostrils are controlled independently, which allows dogs to detect precisely the direction a smell is coming from. And what goes on inside is even more impressive. Essentially, dogs split the flow of air into two separate streams – one for breathing and one for smelling so they can do both at the same time. It’s a superb tool for gathering sensory information.

Birds

Birds can move in any direction they choose. But being able to fly brings with it the constant risk of collision. And they need to protect themselves from their predators in the air, like hawks who can attack birds from anywhere.So, bird brains take in visual information from every direction through this super visual power. Their eyes can see down, up, left, right, in front and behind all at once. It’s an incredible amount of visual information to process but they achieve it effortlessly with a tiny brain

Sharks

Did you know that sharks have magnetic skills? It’s a clever piece of sensory anatomy. Sharks have organs called the Ampullae of Lorenzini which appear as dark openings along the front of their noses. These sensory organs help sharks to sense electric fields in the water. It also helps them find their prey deep in water.They can locate the heartbeat of a crab or stingray even underneath the sand. As that animal starts beating or moving its muscles, it generates a very weak electromagnetic field and that’s when sharks use their sharp magnetic senses.
