When it comes to visualizing environment, eyes play an important role. But there are other ways of navigation such as echolocation used by bats and dolphins. Recently, researchers studying Mexican blind cavefish (Astyanax fasciatus), have found a unique and new method of navigation. These fishes spend their entire life in the deep sea or dark caves, which are devoid of any source of light and so as the name suggests, their eyes are rendered useless and over the time the fish losses their eyeballs.

The popular known fact that bamboo is the only food that panda exclusively feeds on, is not true. Researchers from the Monell Center have found that the panda has also liking for sweet food.

When we talk about intelligence in the animal kingdom, animals like chimpanzees, dolphins or crows are the first one to come across our minds. But it’s time to get over them, because as per the latest research, common goats are way more intelligent than formerly believed.
