2-Foot-Long American Bullfrog Sparks Concern In British Columbia (Photos)

Recently a man named Russ Schut was fishing in Sproat Lake, which is on Vancouver Island (Canada), just northeast of Washington state.

With just a worm as bait, Russ was able to haul in a 2-foot-long American bullfrog (which he released).

Schut posted this picture with the enormous frog thinking that it wasn’t particularly exceptional, other than being impressively large.

But according to GrindTV.com the photograph was noticed and has fueled concern that the,

 “…voracious amphibians are spreading unchecked across the British Columbia island’s landscape. Because they’re not native to the Canadian southwest and have few natural predators, such as alligators, water snakes, and kingfishers in their native American southeast, some of the bullfrogs are growing to abnormally large sizes.”

American Bullfrogs grow to an average length of around 7 inches and weigh up to 1.5 pounds, so the 2-foot-long Bullfrog caught by Russ Schut was defintly abnormal.

Gail Wallin works with the Invasive Species Council of British Columbia. She told Alberni Valley Times that these frogs are,

“Big and voracious…And when you’ve got a species like that, that can basically out-eat some of the native species; it will take away the forage that native species would use and at times they can be aggressive on other smaller-sized, earlier life-cycle frogs.”

A current study at the University of Victoria is mapping the rate of the bullfrogs’ spread. Wallin has theorized that they were initially introduced to the area by people emptying their aquariums, unaware of the environmental consequences.

According to National Geographic, American bullfrogs can lay as many as 20,000 eggs, with tadpoles sometimes reaching lengths of 7 inches. These bullfrogs populate quickly and with few natural predators in the area they also populate effectively. Suitably, a group of bullfrogs is called an army, or colony.

Though native to the American southwest, they now range throughout the continuous U.S., as far north as Canada and as far south as Mexico and Cuba. Their presence also has been documented in Europe, South America, and Asia.

As of now there is no plan to rid the region of the American bullfrog. Check out some images of the American bullfrog below.

This Animal Isn’t A Snake. Think You Can Guess What It Really Is? (Photos)

Professor Daniel Janzen, a biology professor from the University of Pennsylvania, has spent years of his life cataloguing and photographing a very unique group of creatures: caterpillars that defend themselves against predators by looking and acting like snakes.

Check out some more pictures of “Snake Caterpillars” taken by Professor Janzen below:

Snake caterpillars can be found in Costa Rica, Guatemala, Belize, and some parts of Mexico. Their markings resemble a snake’s head, which they can actually use to “strike” at would be predators (though they obviously can’t bite like a real snake would).

Janzen is an ecologist and what most would call a caterpillar expert. He’s been tracking these insects in Costa Rica since 1978 and  has been an expert in the field of entomology (the study of insects) for 50 years.

He splits his time between his labs and the field, spending half the year at the University and the other half in Central America, searching for strange new species of insect like the snake caterpillars.
