With this Kosmos experiment kit, children can breed their own little prehistoric crustaceans and observe the development from Triops egg to fully grown crab in detail. The transparent, extra-large tank features a separate hatching area and detachable swimming zones. It's ideal for observing the animals' behavior and being up close as they grow, molt, burrow in the sand, and lay eggs. Through daily observation and regular care of the Triops, children naturally learn to take on their first responsibilities for animals. The instruction booklet provides optimal support, explaining the breeding and care of the prehistoric crustaceans step by step, while the many exciting research questions and background information encourage ongoing observation and engagement.
