025 Return of the Invertebrates

We back for another invertebrate versus amphibian episode. But this time we’re focusing on carabid beetles and their relentless consumption all amphibian life. They have managed to turn the tables on their would be predator in a remarkable case of role-reversal. Species of the Bi-week is a beautiful frog with a fittingly macabre name. FULL REFERENCE LIST AVAILABLE AT: herphighlights.podbean.com
