Examples of some imaginary animals created by students. A. Scutum squamatum. Habitat: cold and wet areas (Cold Island of SEAM planet; Fig. 2B). Characteristics: bone-shield on a leg, large claws and dorsal spines to capture preys and to protect its hunting territory, a layer of fat under the scaly skin to protect from cold and as energy supply. B. Tritolaus siralis. Habitat: dry and hot areas (Warm Island of SEAM planet; Fig. 2B). Characteristics: cryptic color, ears for sound perception and thermoregulation, claws and jaws to capture and eat prey. C. Tartarus canis. Habitat: land and freshwater (Wild World; Fig. 2A). Characteristics: very long neck to reach tree leaves, flipper-legs to crawl and swim. D. Struthio becchi. Habitat: temperate areas (Wild World; Fig. 2A). Characteristics: large eggs carried in lateral bags under the wings, long beak to break seeds and to bark trees looking for insects, tail feathers to attract partners and for defence (a feather can be removed to disorientate a predator).
