Japanese giant salamander

Andrias japonicus

At the Detroit Zoo
Our Japanese giant salamanders – two males (Bob and Dieter) and two females (Hetsu and Helga) – arrived in 1999 from Japan’s Asa Zoo where they were captive bred from wild-caught parents. Hetsu is shy and often looks to Bob for comfort. Her shyness notwithstanding, she can be pushy at times and will keep Bob out of the cave when she wants to be alone. Bob is anything but shy and will often provide a show for guests so they can get a glimpse of the inside of his massive mouth and tiny teeth.  The Japanese giant salamanders can be seen at the award-winning National Amphibian Conservation Center – a leader in amphibian conservation and research – which houses a spectacular diversity of frogs, toads, salamanders, newts and caecilians.


The second largest salamander in the world, it can reach more than 4 feet in length and weigh as much as 88 pounds. Its skin is a mixture of gray, black and white, and is heavily wrinkled. This species has an elongated body, a long broad tail and two pairs of legs that are similar in size. The eyes are small and positioned on top of the broad, flat head.


Fun Facts

  • Its small eyes make the salamander rely on its other senses to hunt.

  • It can go weeks without eating, if necessary.
