29 TEAM TALK The Cutting Edge By Mariette MY FROG PRINCE(S) “The Frog Prince” … A tale where a Princess befriended a Frog Prince who then magically transformed in to a handsome real human Prince after she kissed him … her own Prince Charming! How many of us wished that this might very well be the case? I am fortunate to have two of these very special “Princes” in our collection at the Snake Park at Bayworld in Port Elizabeth. “Pyxie” and “Sprite” are African Bullfrogs (Pyxicephalus adspersus) who joined the Park as tiny froglets, no bigger than 3cm in diameter, but who very soon grew in to handsome adult frogs. Bullfrogs are also known as “the pixie frog” due to its Latin name (Pyxicephalus adspersus). These magnificent frogs are olive green in colour. The males usually have a yellow or orange throat, whilst the fe- males have a cream-coloured throat. Male bullfrogs grow to be larger than females (usually the males weigh in at an impressive 2 kg, whereas the females are approximately halve the size of the males). These impressive frogs are carnivorous, which means that they get their food from killing and eating other animals. They are quite voracious feeders and will happily ambush their prey and feed on small rodents, insects, other amphibi- ans, reptiles and even small birds! They are also cannibalistic and often the males will feast on their young tadpoles. These frogs have sharp odontodes (sharp, tooth-like projections in the lower jaw) and can bite when provoked or handled. Bullfrogs can withstand the harshest of environments and can easily live up to 35+ years. They can remain dormant (estivate) under the ground during dry seasons. By doing this, they remain cool and damp, although they can not feed during this time. This type of behaviour is triggered by excessive heat and/or dry condi- tions. During this dormant state, their breathing and metabolism will slow down and their body temperature will drop. This will give them enough energy to survive for long periods without food. As soon as the rainy season starts, these frogs will emerge from their underground hiding place. They will gather in water and spend a short, but active season feeding and mating. “Pyxie” and “Sprite” are both males and therefore do not share an enclosure as these animals are quite aggressive (dominant behaviour) towards one another. Usually the larger male will dominate the smaller male by displaying aggressive behaviour. In nature they often injure (and even kill!) the smaller males. 29
