Depends on the animal. Not sure I understand "adult baby," but supposing that means the animal after it's a functioning individual as opposed to a newborn (e.g., a newly-born horse is a foal, no matter the sex, but a young horse is either a colt or a filly), some names are swan: cygnet; eel:elver; goose: gosling or gansel; bear: cub; fox: kit.
Several large animals share the word "calf": whales, elephants, cattle. Some have more than one: rabbit: bunny or pussy (mainly English); sometimes the official name of one is used for another. Human children are humorously called "kids" the proper name for baby goats.
In nature, sometimes when an animal is born, it carries the same name as the adult version of the animal. However, for a baby panda, it is called a cub.
Horse is the term typically used for both the animal and the adult form of that animal. A baby horse is called a foal (Colt for male, Filly for female), foals grow into adult horses.
An adult lamb is called a Sheep. Yes, a sheep's baby is called a lamb.
The word juvenile means not yet adult. You are a juvenile human.
Many young or baby animals do not have the same animal name as the adult animal. A young fowl is called a chick or cockerel.
Hatchling -> baby -> juvi -> adult. An adult leopard gecko would be called an adult.
it is called an adult animal.
Hatchling -> baby -> juvi -> adult. An adult leopard gecko would be called an adult.
Adult male bears.
Depends what baby male animal it is.
Depends on what kind of animal it is for example : a horse's baby is called a foal when it's first born. A dog's baby is called a puppy and a cat's is a kitten. As you can see the name of an animal's baby depends on the animal.
It all starts like this.... A female animal and a male animal has a baby then the baby feeds on the mother then they are separated then the baby grows up to an adult and then it starts all over again...
