As the film turns 50, don't blame ‘Jaws‘ for our fear of sharks, writes Hans Walters of WCS‘s New York Aquarium. But in reality, Walters writes for @nydailynews.com, this group of animals bears little resemblance to the antagonist of the book and film. 🌎 www.nydailynews.com/2025/07/19/t...

Don’t let this news make you feel dizzy but yesterday marked 20 years of spinning at the Bronx Zoo’s Bug Carousel! The merry-go-round opened on July 13, 2005 with 64 kinds of creatures modeled as rides. (28 were beetles!) 1/2
