A talented body painter has created a series of mind-bending illusions that cover entire torsos. Natalie Fletcher’s work are enough to make people double-take, the spiraling patterns of some appearing to fade into the abyss. In other works, the artists designs look as though they are never ending, while some show body parts appearing to protrude from models chests. The idea behind the ongoing series came to Natalie, 30, as a means of keeping entertained during the winter months. Here: Optical illusion bodypaint. (Photo by Natalie Fletcher/Cater News)

Perched on the snout of a crocodile, this brave frog will probably never realise just how much of a lucky escape it's had.

Breaking Bad characters as you’ve never seem them before: Anthony Geoffroy adds his own twist to the already phenomenal characters from Breaking Bad.

It looks like an underwater tornado, but a diver was actually stuck in the middle of a huge school of fish. The fish swarmed around Mika Woyda in their thousands as she swam off the coast of Cabo Pulmo, Mexico. Her husband Caine Delacy snapped the breath-taking images of Mika in scenes he revealed he had never witnessed in 20 years of diving. Before entering the water the couple, who live in Boulder, Colorado, had some shots in mind but never imagined what they would capture. Here: photographer Caine Delacy with his wife Mika Woyda.

Nasar, an Arabian horse, stands in the office of doctor Stephanie Arndt at her home on February 19, 2014 in Holt, Germany.

Mrs. Arndt says she doesn't mind, and though the horse never spends the night, it does occasionally take a nap in the house. (Photo by Patrick Lux/Getty Images)

A young YPJ recruit (in pink) arrives to the training base for her first day in training near Derek City, Syria.
