Unique Dolphin Hunting Style - Driving Fish Onto Land

Dolphins, in particular the bottle nose variety, are incredibly intelligent. Some of their intelligent behavior includes having the know how to kill sharks by busting the sharks gills with their snouts.

Many believe dolphins intelligence rivals our own, and just as with humans, their are bound to be bad individuals. They are also one of the few animals on this planet that are known tool users, using cuttle bones from cuttle fish to protect their snouts while rummaging through the sand looking for flat fish.

The Sardine Run: A Yearly Feeding Frenzy Off South Africa's Coast

One of the most magnificent sights on the planet.  Every year  millions of sardines migrate northward past the south coast of Africa.  This migration has often been referred to as one of the most magnificent wonders of the natural world.

Deepest Living Fish In the World (Video)

A fish called the "Hadal snail fish" (Pseudoliparis Amblystomopsis) is the deepest living fish known to man.  The fish lives in total darkness, at depthes of 25,000 ft deep in the trenches of the Pacific.  At this depth the water pressure is immense, and the temperature approaches freezing.

It was thought that any fish living at these depths must be slow and relatively sparse populated due to the low-energy available in the environment.  But a video filmed by a team of British scientists in 2008 at a depth of more then 25,000 ft clearly shows that they are active, numerous, and even sociable.

Machine with Animal Brain? Or Animal with Machine Brain? (2 Videos)

Two videos from New Scientist show different approaches for the development of cyborgs.  One video shows several different research teams controlling insect flight through electrodes implanted into the insects brain.  What immediately comes to my mind when I hear about this is the potential for military, police, and scientific exploration of hostile environments with these computer controlled bugs.

Blue Whales Have A Very Efficient Feeding Style

An article from New Scientist states that Blue Whales are one of the more efficient eaters on the planet.  A team from the University of California tracked 250+ blue whales as part of a study to determine how the whales can support their high energy demand.  The massive amount of calories needed by the whales is due to their large size and  migratory lifestyle, along with having to live with the sparse prey populations for a significant portion of the year.
