Froggy lunch, surf-loving penguin and a standout treehopper crown this week in wildlife

This Guardian week-in-wildlife roundup highlights striking images and short notes from around the world—such as a garter snake preying on a pickerel frog, a young penguin riding waves off Rio, and protected goats on Turkish slopes—along with a feature on a treehopper vying for Invertebrate of the Year and broader conservation themes like desert rain frogs threatened by mining and England’s £60 million crayfish protection programme.
