Depends on the animal
Almost all animals begin as an egg and a sperm. There are a few exceptions, though, such as sea sponges. But for the majority, they begin as sperm and egg.
No
Examples of sexual reproduction in animals include the mating of birds where sperm fertilize eggs inside a female bird's body, the mating of mammals like lions where sperm is transferred from male to female, and the spawning of fish where females release eggs and males release sperm into the water for fertilization to occur externally.
Squid are regular prey animals for sperm whales, making up a significant percentage of their diet.
Returning animals to the same place they are collected from is important for their well-being and survival. Animals have evolved to adapt to their specific habitats and ecosystems, so familiar surroundings provide them with the resources and conditions needed for their survival. Moving animals to new locations can disrupt their established social structures, foraging patterns, and breeding behaviors, putting them at risk of stress, injury, and even death.
It is usually collected ONLY AT the sperm bank so it can be placed in a controlled temperature environment before freezing.
No, not all animals have sperm. Amoebas and some other protists are technically animals but reproduce asexually instead of with sperm and eggs.
copulation
Sperm collected from the mouth is unlikely to be viable for fertilization due to exposure to saliva, which can damage sperm cells and alter their motility. Additionally, the mouth is not a suitable environment for sperm storage or preservation. For successful reproduction, sperm needs to be collected in a controlled manner, typically from the male reproductive system. Therefore, while theoretically possible, using sperm from the mouth would not be practical for reproductive purposes.

All animals produce about the same amount of sperm.

Like all other animals there are female Sperm whales.
It is called artificial insemination.
