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.
