I saw this on BBC news and thought it would be interesting. Apparently they have a giant salamander in  Maniwa City, Japan at the Visitors Center in a tank. This salamander is called a hanzaki and is five feet and six inches long. Normally salamanders are one foot and two inches long. That's almost five times as long as an average salamander! If you're thinking that that hanzaki was big, they found a story from the 17th centuary where that salamander was about thirty-two feet and ten inches long! The link to that article is here  http://news.bbc.co.uk/2/hi/science/nature/8497330.stm
