Triops Longicaudatus (aka Triops) are fascinating creatures that first came into existence during the Triassic era, long before T-Rex ruled the Earth. Their eggs evolved to survive periods of drought, only to hatch once there had been sufficient rainfall. This rare characteristic enables us to safely store them until a time when it is convenient to care for them. Their relatively simple care, fascinating properties, energetic behaviour & short life-span, makes them excellent educational project for schools whilst being fascinating & fun for any family. The small pack contains Triops eggs, instructions for their care, food, water conditioner & a handy Thermo-Strip" to ensure the water stays at the optimum temperature. 7cm"
