The Toad is the Rhinella Marina. The Cane

The Cane Toad, or otherwise known as the giant
neotropical toad or marine toad, is native to South and mainland Central
America. The official scientific name of the Cane Toad is the Rhinella Marina. The
Cane toad is a member of the genus Rhinella, but was formerly in the genus
Bufo, and that’s where it gets its scientific name. Cane Toads can grow to be
10-15 cm in size and reproduce at a very fast rate. Cane Toads are prolific
breeders, and females lay single clump spawns with thousands of eggs. Back in
the 1930s, farmers in Queensland, Australia, were having issues growing sugar
cane. The farmers’ in Queensland’s’ fields of sugar cane were being eaten by
Cane Beetles, and those farmers did not want to resort to using pesticides to
contain the beetles. If they had done this, it would have contaminated their
crops and killed their businesses. Word went around that there was a toad that
had a big appetite and loved nothing more than eating Cane Beetles. Farmers
then requested scientist to introduce Cane Toads into Australia to protect
their sugar cane and control their pest problem. After lots of debate and
research, they finally came to the consensus to deliver Cane Toads to the
farmers. Scientist thought that the Cane Toad could control the farmers pest
problem and prevent the sugar cane destruction. The scientist turned out to be incorrect
though, and the sugar cane problem was not solved. What the scientist did not
expect though was that in that area, the Cane Toad had very few predators. Why
did the Cane Toad have no predators in that environment? The reason for that is
because the Cane Toad hardly has any predators to begin with. The reason that
Cane Toads have very few predators is because they have poison glands. These
poison glands let the Cane Toad’s excrete poison onto their skin, making them
much tougher prey to their predators and limiting the amount of predators they
have. Their poison is deadly, and human deaths have even been reported from
touching Cane Toads. Not having any predators in their new environment allowed
the Cane Toads to reproduce at very high rate. This high rate of reproduction
expanded the Cane Toad population by multiple times, making them an invasive
species. Cane Toads soon took over western Australia, and have become the
dominant species, with over 200 million of them. Solving the sugar cane
destruction problem was not a success, and what resulted was a problem that’s
far worse.
