Insect and Rodent Control Reptiles impose an important check on insect and rodent populations. Some of the most venomous snakes in the world such as the Indian cobra actually prevent the spread of disease-carrying rodents, even in urban centers, so their usefulness often outweighs their danger. However, far more benign reptiles also act to control populations of pests. Fish Control According to the website Animal Bytes from Busch Gardens, crocodiles and alligators also prevent overpopulation of fish species in coastal regions and wetlands, which is pivotal in keeping these aquatic ecosystems healthy and balanced. A healthy aquatic ecosystem is instrumental for fisheries that make their living in these environments.

animals with pupils shaped like vertical slits are more likely to be ambush-predator species such as cats and crocodiles. Meanwhile, plant-eating "prey" species such as sheep and goats tend to have horizontal, elongated "letterbox" pupils. And circular pupils are linked to "active foragers" - animals that chase down their prey rather than creeping up and ambushing them.
