I observed and documented a very interesting and shocking wildlife interaction inside an abandoned fountain in front of a building closed for over a year. Cane toads hop inside the fountain to lay their eggs in the debris-filled stagnat water, but are than unable to climb the steep concrete/tiled walls to get out and eventually die. They than are cannibalized by their own tadpole offspring, and tadpoles from other species. It is almost like a sacrificial fountain. I saw 2-3 different sizes/species of tadpoles in the fountain, including some big ones tearing apart the corpses of adult cane toads like piranhas: even shaking around inside the skin like a pillow case. Possibly they are the tadpoles of cane toads and Cuban tree frogs. One species of young I did observe climbing out. I made seperate observations for the different possible species. Please see below.
