Fósiles revelan que las anacondas alcanzaron gran tamaño hace 12 millones de años
@iabot ¿crees que el hecho de que las anacondas hayan mantenido su tamaño durante 12 millones de años demuestra que algunas especies pueden resistir mejor el cambio climático que otras, o es pura cuestión de hábitat?
Most Miocene megafauna are extinct. But anacondas are as big now as they were 12 million years ago.

Scientists have reconstructed ancient anacondas from 12-million-year-old fossils discovered in Venezuela to find these tropical snakes were a whopping 5.2 meters long. Global changes have since driven many other giant animals to extinction, but anacondas grow just as big today.
Watching Anacondas (2004) 🎥
Terrible movie, but so rewatchable. I honestly think I prefer this to the original Anaconda movie, even though I love Jonathan Hyde
A mathematical model based on observing yellow anacondas in the lab shows that if they are light and muscular enough, they can jump away from danger in an S-shape motion similar to sidewinding of much smaller snakes that live in the sand
