The Common Surinam toad feeds on all small aquatic organisms.
It hunts primarily invertebrates, especially insects and their larvae, which it digs out of the silt with its thin fingers and rapidly places in its mouth.
This distinguishes them from frogs, which croak or retch. The jabber has a different sound, similar to that of a rattle. You can listen to it on the National Forest website.
The lungs are not symmetrical. On the right side they consist of two lobes and on the left side they consist of one lobe. Below the lungs is the diaphragm.
