The captured frogs probably arrived on palm trees from Florida that were planted in the zoo in 2016, USGS research ecologist Brad Glorioso wrote in a study published in the April issue of the journal Biological Invasions. “They have noxious skin secretions, lay their eggs in bird baths and fish ponds, and they can clog plumbing and cause power outages by short-circuiting utility switches where they seek refuge,” he said in a news release. They could easily cross the river on vehicles, boats, barges or debris and prey on smaller frogs, he wrote in the article. Local treefrogs are considerably smaller than Cuban treefrogs, said Jeff Boundy, a herpetologist with the Louisiana Department of Wildlife and Fisheries’ Natural Heritage Program. “The natives are about a quarter- to half-dollar-size on your kitchen window at night. These guys get up to five and a half inches (14cm) in body length. You’re talking about a fist-sized frog now,” Boundy said in a phone interview.
Frogs not the enemy – people are – they transplanted trees that were ferries for the frogs – duh –
