  1. TROPICAL FROGS 3-25-08 Sounds of the Tropics

  2. SIZE: THE RANGE IS HUGE Bufo marinus from Surinam Bufo metamorph.

  3. PAROTOID GLANDS ON TOADS PRODUCE TOXIC ALKALOIDS

  4. Taken in large amounts, the alkaloids are potentially deadly. Taken in small amounts, they may be hallucigenic (and unlawful). My dog, Rex, bit toads several nights in a row. Maybe he liked it – swollen eyes and all!
