It does not include tetrapods (four-limbed vertebrates such as amphibians, reptiles, birds, and mammals) which share a more recent common ancestor with some fish species.
Depending on the species, some snakes eat primarily small mammals, such as mice, rats and squirrels. Larger species feed on larger mammals. Some snakes feed on amphibians, some on earthworms, some eat birds, some eat fish and others may eat other snakes.
All mammals are chordates. Mammals include such animals as humans, dogs, monkeys, etc.
