Bottlenose dolphin - blowing air rings underwater

STA-82 Bottlenose dolphin - blowing air rings underwater Distribution: Worldwide except polar regions Tursiops truncatus Complex play / creative behaviour: dolphins often play with the bubbles or rings of air they create, both visually and by using sonar. They appear to enjoy biting the vortex rings, so that these burst into many seperate normal bubbles, which then rise more rapidly to the surface. They also play games, diving through the bubble rings for fun! Augusto Leandro Stanzani Please note that prints are for personal display purposes only and may not be reproduced in any way

Megalodon shark and great white

Megalodon shark (Carcharodon megalodon), computer artwork. A great white shark (Carcharodon carcharias) is shown below it at the same scale. This enormous shark lived between around 20 and 1.2 million years ago, and is known from fossils. It was related to the modern great white shark, and is thought to have fed on whales, as this is the only source of food that could have provided it with enough meat. Megalodon was thought to attain lengths exceeding 20 metres, and possibly significantly larger. It is thought that it died out after the seas cooled, allowing warm-blooded whales to escape the sharks for much of the year by swimming to waters too cold for them to survive in
