"Dinosaur Shrimp"

Strange stuff in Arizona:

After hatching, Triops can grow up to 1.5 inches (4 centimeters) long, with a shield-like carapace that looks like a miniature helmet, according to Central Michigan University. Their eyes make them look angry and wise at the same time — they have two large, black-rimmed compound eyes (like those of a dragonfly or bee) and a small ocellus, or simple eye, between them. Ocellus eyes are common among arthropods (a group that includes insects, crustaceans and arachnids), which are filled with simple photoreceptors that help these creatures detect light, according to the Amateur Entomologists' Society. 

In this case, the Triops at Wupatki National Monument got lucky with a short but intense rainy spell. Usually, Wupatki gets around 9 inches (22.9 cm) of rain a year, Carter said. In 2020, Wupatki had its driest lowest monsoon summer on record, with just 4 inches (10.2 cm) of rain, Carter said. But in the last week and a half of July 2021, the region got a tumult of rain: nearly 5 inches (12.7 cm).
