• Batrachomoeus Trispinosus , the three spined toadfish looks as hard as a rock. With its fat head and wide , high set eyes like to lurk camouflaged on the floor of swamps. But under pressure , the fish's behaviour is rather more spineless than its name suggests " it's is the only fish known to cry like a baby".

      It is the only fish known to produce non - linear calls. Linear sounds , such as those produced by other fish have a regular wave form a bit like a sine wave. In non linear sounds, however different waveforms interfere with one another , creating a much more complex signal. Human babies , other mammals and song birds use non linear sounds in their calls, and animals associate such sounds with a sense of urgency.
