The wingless midge — reaching up to 6 mm (0.24 in) in length — is Antarctica's largest permanent land animal. It survives the year-round cold by burrowing, losing up to 70% of its body water, and producing antifreeze-like proteins. Without wings, it sheds less heat and avoids being blown out to sea.

Skeleton shrimp are skeletally thin and often have ghostly transparent bodies. They grasp algae with their spindly rear legs, while their front legs form large "claws" used for grooming, defence, and capturing prey. Luckily, they only grow to a couple of centimetres (~1 inch) long.

The common cockchafer spends its first 3 to 5 years below ground, growing as a larva. Then, all at once, these beetles emerge as adults in great numbers during spring. They clumsily buzz about, using their frilly antennae to find mates and reproduce — they live for only 6 weeks in this form.
