Depends on the species. Average size for a California King snake adult is around 5 feet.
They're relatively short for a snake - average adult size is about 39 inches (1 metre)
At the adult stage they grow to be about 4 to 6 feet in length
It depends on the size of the snake. The vivarium should be at last half the adult snakes length. on its longest side - and a quarter of the adult snakes length for the measurement front to back.
Adult size varies considerably. Specimens can be up to 7 feet (2.1 metres) in length.
Obviously this depends on the size of the human. But if we're talking about an average adult male and an average adult snake... I'd say 3-4 times the height/length of a human.
That would depend on the length and circumference and muscle mass of the sidewinder snake. Giving an approximate amount would need specific information.
The average size is around three feet - however - there are always exceptions, and there have been reports of specimens up to five feet in length.
a crown in the size of the teeth
In crown of thorns starfish, there is no significant size difference between males and females; both sexes can reach similar sizes. Typically, adult crown of thorns starfish can grow up to 40 centimeters (about 16 inches) in diameter. Their size can vary based on environmental conditions and availability of food rather than sex.
Birds, mammals and fish. It all depend on the size of the animal that's hungry and the snake it wants to eat.When they're babies, the snake gets eaten by fish and frogs. As an adult, it's eaten by birds and mammals.
Take a snake and hold it in your hands. The fact that you can hold it in your hands proves the snake is much smaller than you. Most common, non-tropical snakes (rattlesnakes, vipers, garden snakes, and just about any snake that lives in the US) are quite small, with their heads being able to fit in the palm of the average adult human twice, maybe thrice, over. The only snakes that are larger than the average adult human are boas, pythons, and anacondas, with their heads being as big as the adult thigh, or maybe upper arm. With that in mind, most common snakes have brains that are dwarved by the size of the human brain.
