This spiky tenrec was spotted in Madagascar’s Mantadia National Park in the last decade of September 2025. Mostly nocturnal and rarely seen, it puffs out its spines when threatened.

Skeleton involves a person riding a small sled down a frozen track while lying face down. The sport is a more intense form of luge because skeleton competitors leap onto the sled and slide downhill head first. Skeleton athletes can reach up to 80 mph on straightaways, causing forces up to 5g, so the helmet is a critical component for attitude as well as safety.
