The newly hatched sunfish is tiny, measuring about 2,5 mm (0,1 in).
If they are lucky enough to survive and develop into fry, they need only 15 months to achieve a size of an adult. To increase the chance of survival, juveniles swim in schools.
Most snails are herbivorous, but there are also carnivorous and carrion-eating species.
Terrestrial animals feed mainly on plants, although there are predators among them. Predatory land snails hunt other slowly moving organisms, so they prey on other snails or earthworms.
