Three-Eyed 'Dinosaur Shrimp' Emerge After Arizona Monsoon

Thanks to a monsoon rain in Arizona, hundreds of odd-looking critters have popped out in a temporary lake in the area. These prehistoric-looking creatures that emerged from tiny eggs are called Triops. The reason for their sudden appearance is a unique trait of their eggs. According to Central Michigan University, their eggs can lie dormant for decades in the desert until enough rain falls to create lakes that provide real estate and time for the hatchlings to mature and lay eggs for the next generation.
