Do you know the difference between venomous and poisonous? Poisonous is where you have to absorb, inhale, or swallow the toxins while venomous is where the toxin is injected into you. Most people know about poisonous frogs such as the many different species of dart frogs. But do you know about venomous frogs? Maybe now you are thinking about the fangs that these frogs must have to be venomous but guess what? They don’t have any. They use a spike on their head to inject venom as a defensive mechanism. A single gram of their poison could kill 80 people. I wouldn’t try to handle these frogs without gloves.
The Bruno Casque-headed Frog lives in the rainforest and the coastal restinga shrubland, often hiding in the holes of bromeliads and shrubs during the day. They move backwards into these holes and then plug the hole with their weird shape head. This helps protect against water loss.
The International Union for the Conservation of Nature (IUCN) Red List assesses the Bruno’s Casque-headed Frog as Least Concern for Extinction. The frog has a large range and a presumed large population. Only potential threat to them is the increase of agriculture and grazing in the area.
