Praying mantises normally eat other insects, but they aren't picky. They've been seen eating spiders, birds, frogs, and mice, but now a science paper details the first-ever observance of a praying mantis catching and eating fish. Lots of fish.
Observations of this 2.2-inch-long male mantis (Hierodula tenuidentata) were made in a private roof garden in Karnataka, India. The garden may be artificial, but the researchers say it’s a very close approximation of mantises’ natural habitat, featuring wasps, butterflies, spiders, and several planters. The team observed the mantis as it hunted and devoured the guppies, also known as rainbow fish, in a pond, which it did for five days in a row. In total, the mantis ate nine fish, at a minimum rate of two per day.
This is just one mantis, but it shows how adaptable and intelligent they can be. Read all about the pescetarian mantis at Gizmodo.
