They both lay eggs to reproduce
Simply put, birds are evolved from small dinosars, and dinosaurs belong to the same group that crocodiles belong to, archosauria, while turtles belong to the group sauropsida, because, while they appear to be more similar to crocodiles than birds, the evolutionary common ancestor they share is far more ancient, unlike that of crocodiles and dinosaurs. That's evolution for you.
Birds. The reason is that both crocodiles and dinosaurs are archosaurs, and birds evolved from dinosaurs.
Birds are the closest living relatives to crocodiles. Both birds and crocodiles are members of the group Archosauria, which also includes dinosaurs. This shared ancestry can be seen in similarities in their skeletal structures and reproductive systems.
Small crocodiles eat frog(amphibians) ,small birds and fish. As adults crocodiles eat mammals like wilde beasts, fish, birds and snakes.
there are birds, lions,and crocodiles
Egrets and herons are commonly seen near crocodiles, as they often feed on the same fish and insects found in the water. These birds are generally not threatened by crocodiles as they can fly away quickly if needed.
Four chambers.
Any water/shore bird that comes too close.
American Crocodiles are eaten by many things as baby's. This includes: birds, fish, other crocodiles, snakes, turtles, reptiles, and anything that is interested.
The presence of a similar skull structure and the presence of scales on their skin suggests that crocodiles and birds share a common ancestor. Additionally, their common ability to lay hard-shelled eggs further supports the theory of a shared ancestry.
Crocodiles clean their teeth by opening their mouths wide and allowing small birds called "crocodile birds" to pick food bits and debris from between their teeth. This cleaning symbiosis benefits both species as the birds get a meal and the crocodiles get their teeth cleaned.
The heart of crocodiles has a more complex structure compared to other reptiles. It has a four-chambered heart similar to birds and mammals, allowing for efficient oxygenation of blood. This adaptation enables crocodiles to have greater endurance and performance in aquatic environments.
