Alligators, crocodiles and snakes will attack, bite and kill us if we allow it, but some humans should never be trusted.
With these reptiles, size does matter in this specific instance. They eat each other, depending on which is bigger. Alligators, snakes and crocs are apex predators, and actively hunt and kill to survive. Yes a large Anaconda or Python can and have killed Crocodiles.
And interestingly they are related These animals that are closely related is the crocodile and snake. Snakes and crocodiles are both a member of class reptilia.
However, Crocodilia, are more closely related to mammals than snakes are. This is because both birds and crocodilians share a common ancestor with dinosaurs, making them part of a group called Archosauria. On the other hand, snakes are part of the Squamata order, which is more distantly related to the line leading to mammals. Hence, by examining the evolutionary lineage, it is evident that crocodiles are closer relatives to mammals than snakes are. This finding is supported by phylogenetic classification, which groups organisms based on their evolutionary history.
