Looking like an orbiting spaceship, a stingless jellyfish swims just under the surface of a remote lake in Surigao, Philippines, 3 February 2010. The creatures, which can sometimes be found in their thousands near the surface vary in colour from a bright yellow to a bluish white and are found in only a few places in the world including this lake and another in Micronesian Palau. It is believed that the species became cut off from the sea and their natural predators, possibly by volcanic activity, many thousands of years ago, and their venomous stings evolved away

Two orphaned baby flying foxes being cared for by Sandra Penman of Holmesville, Lake Macquarie, Australia, 8 February. The Australian government has come under fire for its policies towards the culling of fruit bats. According to one ecologist, fruit bats are dying slow, cruel deaths because of culling methods approved by the state government. University of Sydney ecologist Dr Kerryn Parry-Jones has studied the animals for more than 20 years. And she believes the government is breaking animal cruelty laws by allowing farmers to shoot the bats. She cited a study showing up to a third of all shot bats were still alive more than eight hours later. The problem has seen increasing numbers of baby fruit bats being discovered orphaned after their parents have been killed

Other vultures panicked and took to the skies - but because this one was so big it struggled to leave the ground. The pair circled each other, with the fox trying desperately to land a killer blow until the mighty bird eventually managed to take off
