Some interesting amphibian facts:

  • Wisconsin has 12 frog species; all are mostly nocturnal
  • Amphibians shed their skin periodically. It is based on season, climate, and food supply. Many eat their shed skins for their nutrients.
  • To avoid predation, their best defense is to remain undetected.
  • Toads emit a burning sensation and puff up their bodies, making it difficult to swallow.
  • They overwinter by producing a glycol-like fluid that allows their body fluid to freeze but not the cells.
  • Habitat loss and fragmentation is the cause for population declines.
  • Frogs and salamanders are indicators of environmental conditions because their skins are vulnerable to pollutants.
  • Amphibs offer a number of benefits, from high-quality food for other “critters” to skin secretions that are used for medicinal purposes.
