The Safari Ltd. figurine set clearly illustrates the life cycle of the earthworm (Lumbricus terrestris). With four detailed models, children learn about the biological development of this useful soil-dweller. The phases include the characteristic lemon-shaped eggs, the hatching of the young, the growing worm, and finally the adult animal with a length of about 9 centimeters. The lovingly crafted models are ideal for biology lessons, educational purposes, or as decoration. All figures are non-toxic and BPA-free, ensuring safe handling.
