This photo taken on Wednesday, June 5, 2019 and provided by the Phoenix Zoo shows a big-eyed baby pygmy owl, one of four hatched at the zoo three weeks ago under a special breeding program. The cactus ferruginous pygmy owls are being raised by two pairs of adult owls. Three pairs of the tiny owls laid 11 eggs among them, but only four hatched. The owls weigh just 3 ounces as adults and nest in the cavities of the saguaro cactus. Its population has declined in recent decades and the species is now believed to number fewer than 100 in the state. (The Phoenix Zoo via AP)

This April 2019 photo provided by Audrey Velasco-Hogan shows a dragonfish during a specimen collection session along the coast of San Diego, Calif.
