When it comes to turtles, gender reveal parties are a natural affair, and it's all thanks to the temperature of their nest. Here’s how it works: if the nest is warm, more females are likely to hatch, but if it’s cooler, more males emerge. In other words, the temperature literally decides if the turtle eggs will be "guys or gals." 

Think of it as nature’s thermostat playing a game of gender roulette. A few degrees up or down can tip the scales, which means climate change could make a big difference in turtle populations. It’s an fascinating temperature trick that makes you appreciate how nature loves to keep things interesting.
