Deadly Amphibians looking for love:Poison Dart Frogs breeding at SEALIFE Brighton. Regular showers have done nothing to cool the ardour of one group of testosterone-fueled males in Brighton. Quite the opposite – they have convinced the male poison dart frogs in the Sea Life Centre’s rainforest attraction that breeding season has arrived.The colourful jungle hoppers which produce a skin toxin used by Amazon tribes to tip their spears with, have begun a noisy serenade of croaks and chirrups in the hope of attracting mates. Pictured is one of the species Golfodulcean in full song. photo ©Julia Claxton
