Orcas are at it again. Earlier this month, three orcas were spotted off the coast of Lisbon, Portugal, swimming alongside a boat and ramming it so forcefully that it sank. It was towed back to shore and the crew on board was unharmed. This isn't the first time the behavior has been documented in the region, but scientists have new theories about why they do it.

On the mountains, things can turn perilous in an instant—as this skier discovered when he was swallowed up by a crevasse. #ExtremeRescues is streaming on @hulu.

In the Sulfur Cave, located between Albania and Greece, scientists discovered gigantic spider webs home to more than 110,000 spiders. The web is so heavy that it's collapsing at points, only to be reconstructed by the spiders. While most of the world's caves are characterized by food scarcity due to a lack of sunlight, sulfidic caves like this one are rich in food and biodiversity. In this case, biofilms covering the sediment, midges and their aquatic larvae, and the huge spider colony all contribute to a unique and thriving ecosystem.

My first self-appointed, unofficial acting gig. I drew inspiration from one of my heroes, the crocodile hunter himself. Thanks for getting me my highest grade ever in school, a C- 😂 #ChrisHemsworthRoadTrip is now streaming on @disneyplus and @hulu

A chance encounter led to the discovery of a massive new insect—and yes it's in Australia. Resembling more of a branch than a twig—and weighing about the same as a golf ball—this stick insect is the largest collected example of the species that's now called Acrophylla alta. Its surprising weight and size have researchers referring to it as the heaviest known insect in the country. Uncover more about these monster insects at the link in bio.
