In two different locations in the coast of Hawaii, scientists have observed unusual interactions between bottlenose dolphins and humpback whales as dolphins “rode” the heads of whales: the whales lifted the dolphins up and out of the water, and then the dolphins slid back down. In the video published by the American Museum of Natural History, the two species seemed to cooperate in the activity, and neither displayed signs of aggression or distress. Whales and dolphins in Hawaiian waters often interact, but playful social activity such as this is extremely rare between species.

World’s top 6 biggest prehistoric crocodiles ever lived
Previously, I published a post about the largest crocodiles ever recorded. All sizes in that post were recorded in the recent times.

So, what was the World’s biggest crocodile ever lived? Here are the top six candidates.

Moon Transiting the Earth – EPIC View
An “EPIC” animation of the Moon transiting the Earth created with actual satellite images of the far side of the moon, illuminated by the Sun. The images are taken by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope attached to the Deep Space Climate Observatory (DSCOVR). While the moon was crossing between the DSCOVR and the Earth, EPIC took these beautiful photos almost one million miles from Earth.
The distance between the Moon and Earth varies from around 356,400 km to 406,700 km at the extreme perigees (closest) and apogees (farthest).

Alligators can often reach at least 14 or 15 feet in length, which is even larger than some crocodile species, but not all of them, especially not the Saltwater Crocodile (I am talking about the American alligator – A. mississippiensis here, the Chinese alligator – A. sinensis is much smaller). But what is the largest alligator ever measured?
