Pennant-winged Nightjar (Macrodipteryx vexillarius)

… a species of nightjar that is native to Central and Southern Africa. Like other nightjars the pennant-winged nightjar is mainly crepuscular (active during dusk and dawn) and feeds for insects which it catches in flight, drinking is also done mid flight. When resting pennant-winged nightjars roost on the ground using their coloration to camouflage themselves. When disturbed they will usually flee to a tree branch where they will perch lengthwise.

The long pennants that they are named after are only found in the males. They use them in complex display flights to woo females, and sometimes they even are joined by females.

Franco Banfi

A swiss diver, captured these pictures of one of the six anacondas he saw on his 10 day trip to Mato Grosso in Brazil. This one was about 26-feet long.

"At the first moment it’s scary because you don’t know the animal and everybody says it’s dangerous. ‘But after a while you understand that nothing happens if you respect the snake. ‘I have never been so close to a snake like this before. But I think a small poisonous snake is more scary than a big one. At least you can see the anacondas clearly and know what they’re doing." - Franco Banfi

These are fins from a 500lb Bluefin Tuna

Tuna are members of the Scrombrid family, a group of fast swimming, partially warm-blooded apex predators, with highly streamlined bodies and retractable fins. 

In the image above, the large dorsal fin, with its rigid bony rays, can disappear completely into a deep groove on the body.This gives the fish its distinctive bullet shape, as it charges forward in the water. The fin is pulled out when the fish is slowing down, or turning to keep its cylindrical body from rolling over.

The distinctive little fins, or finlets in the last image are only found in this group of fish. Muscles beneath the skin allows them to move independently. There’s a few people out there researching this, but at the current time their exact function is unknown.
