Cane Toad
The Cane Toad (Rhinella marina) is a large, terrestrial amphibian native to South and Central America, notorious for its disastrous introduction as an invasive species in Australia.
History & Introduction
- Originally introduced to Queensland in 1935 from Hawaii (which had sourced them from Puerto Rico) in an attempt to control sugar cane beetles.
- The biological control effort failed as toads did not prey on the beetles but instead proliferated rapidly, causing significant ecological damage to native Australian fauna.
Control Strategies: Intraspecific Cannibalism
Recent scientific efforts focus on exploiting the toad’s unique biology to curb its population growth.
- Mechanism: Leveraging intraspecific cannibalism where larger toads prey upon smaller ones.
- Objective: To accelerate population decline by encouraging natural predation within the species.
