Behavior

Giant marine toads are primarily nocturnal. Although most toads are solitary, if insects are plentiful, one may find a gathering around a pond or pool, sitting in the glare of a street light and picking off numbers of insects. During the day they can be found beneath fallen trees, leaves, rocks or vegetation. The secretion of the paratoids is highly toxic. It will burn the eyes and may inflame the skin. Dogs or cats that bite this toad will sicken and may die.


Reproduction

Giant marine toads will breed year round if temperature and rainfall are adequate. The eggs are laid in long strings (one from each ovary) in long standing water such as ditches, canals, streams, ponds and fish ponds. Eggs and tadpoles are poisonous and displace native tadpoles. Larvae are tolerant of high temperatures.


Wild Diet

Insects, small mammals, some vegetation, carrion and even dog food.


Zoo Diet

Crickets, mice, depending on size of animal.
