Guardian of the Mangroves – Overall Winner. Tanya Houppermans, Cuba. A curious American crocodile (Crocodylus acutus) swims right up to Tanya, at Gardens of the Queen (Jardines De La Reina), an archipelago off the coast of Cuba. It has been strictly protected since 1996, and is one of the most untouched marine ecosystems in the world. ‍ “The healthy population of American crocodiles is down to the pristine condition of the mangroves and I wanted to capture close ups of this gentle giant in its natural habitat. I hope this image can illustrate that protecting areas like this is so critical”. (Photo by Tanya Griffin Houppermans/Mangrove Photographer of the Year)

Aerialist Erin Blaire, 33, performs a hair hanging trick for a photographer while hanging from a metal bar on a subway platform on March 14, 2023 in New York City. Erin Blaire, originally from Vermont, has lived in New York City for eight years and has been performing her aerial hair routine for the last three. The origin of hair hanging is believed to have originated in China, according to reports, and is a closely guarded circus trick passed from mentor to mentee. Although it is possible to find the technique and secrets online it is most-likely not how professional performers learned the skillset, and not how Blaire did either.

Close Encounter of the Insect Kind: “Check out the awesome face on this praying mantis. I can't get over the mouth, it's like something from a science fiction movie. Of all photographic styles macro is definitely my favorite. I am constantly amazed, in every photo that I take, by the intricate level of detail that exists on even the smallest of creatures. It's a stark reminder that a very complex and infinitely beautiful world exists just beyond our human-sized level of perception. Photo taken in Donnybrook, Queensland, Australia” – Andrew Young.
