Turtle, **** stars: Came with super cute case, not the fastest, but outlasts every comparable unit. Dropped into a pond and still works perfectly. Otter, *** stars: Sturdy build, totally winter-ready and waterproof. Only comes in brown. Launched by the Oregon Zoo and quickly picked up by zoos, aquariums, scientists, and the funny people of Twitter, #rateaspecies is a global, viral hit, and a chance for people to honestly - and hilariously - review the animal kingdom. In Rate A Species, the Association of Zoos and Aquariums has crowd-sourced 150 of the best entries, the majority of which are new to the book, from their 233 member zoos and aquariums. Packed with adorable photographs of every animal and laced with wit and humour, Rate A Species is the perfect gift or self-purchase for animal lovers of all ages.
