The maximum length for males is approximately 8 centimeters, while the maximum length for females is approximately 10 centimeters. Toads that are common are usually brown or olive-brown in color, but their appearance can vary greatly; females are frequently reddish or have warts that are reddish in color. The appearance of the skin is frequently that of being dry and 'warty.' As a result of the potent toxins that are found in the glands of the skin, many potential predators learn to avoid eating toads. Additionally, toxins can be found in the skin of the tadpoles.
The migration behavior of common toads is driven by a strong instinct, and they always take the same path back to their ancestral breeding ponds in the spring. In the spring, they assemble in these ponds, often a couple of weeks after the breeding season for common frogs has ended. Adult toads migrate away from ponds after a mating time that is much shorter than the average frog's (typically not more than a week), and they are far more tolerant of dry environments than the common frog.
The nighttime hours are when common toads spend the majority of their time hunting for prey, which often consists of invertebrates such as ants, beetles, snails, slugs, and spiders. They are able to lead a sedentary lifestyle if they discover a reliable supply of food. During the warm summer months, it is not uncommon for them to stay in gardens for extended periods of time. Toads lay their eggs in strings rather than clumps, and their tadpoles are dark and swim in schools, in contrast to the typical frog, which lays its eggs in clusters. It is possible for large numbers of toad let’s to emerge from ponds in the early summer, typically after it has rained
