Some anime that revolve around the theme of captivity include "Attack on Titan," where humanity is forced to live within walled cities to protect themselves from giant humanoid creatures; "The Promised Neverland," which follows a group of children trying to escape from a sinister orphanage; and "Deadman Wonderland," where the protagonist is falsely accused of a crime and sent to a twisted prison where inmates are forced to participate in deadly games. These anime explore the psychological and physical struggles of characters trapped in oppressive and restrictive environments. **

Frogs and toads eat a variety of live insects and invertebrates in captivity, such as crickets, mealworms, waxworms, and earthworms. Some larger species may also eat small mice or fish. It's important to provide a varied diet to ensure they receive all the necessary nutrients. Additionally, it's crucial to dust their food with calcium and other supplements to prevent nutritional deficiencies. **

Mallards are typically bred and raised in captivity through controlled breeding programs. Breeders select healthy, genetically diverse individuals to ensure strong offspring. The ducks are provided with proper nutrition, housing, and care to promote healthy growth and development. Once hatched, the ducklings are raised in a safe and secure environment until they are old enough to be released into suitable habitats or kept for display or breeding purposes. **

Whales in captivity face numerous challenges, including restricted movement, social isolation, and stress. Keeping these intelligent and social creatures in small tanks for entertainment purposes can have negative impacts on their physical and mental well-being. It is important to prioritize the welfare of whales and consider alternative ways to learn about and appreciate these magnificent animals, such as through responsible whale watching in their natural habitats. **

Freedom can be seen as a form of captivity when it is limited or restricted in some way. For example, someone may have the freedom to choose their career, but if they are limited by financial constraints or societal expectations, they may still feel trapped. Additionally, too much freedom without guidance or structure can lead to feelings of overwhelm or indecision, which can also be a form of captivity. Ultimately, the concept of freedom is complex and can be interpreted in various ways depending on individual circumstances. **

As of now, there are no great white sharks in captivity in any aquarium or marine park around the world. Great white sharks are difficult to keep in captivity due to their size, swimming needs, and feeding requirements. Most facilities do not have the resources or space to adequately care for a great white shark, so they are typically not kept in captivity. **

Keeping birds in captivity is a controversial topic, with opinions varying widely. Some argue that keeping birds in captivity can be considered animal cruelty, as it restricts their natural behaviors and freedom. Others believe that responsible captivity can provide birds with proper care, nutrition, and protection from predators. Ultimately, the welfare of the bird and the conditions in which it is kept play a significant role in determining whether keeping birds in captivity is considered animal cruelty. **

Mallard ducks are typically bred and raised in captivity through controlled breeding programs. Breeders carefully select pairs of ducks with desirable traits, such as health, size, and coloration, to produce offspring with these characteristics. The ducks are provided with a suitable habitat that mimics their natural environment, including access to water for swimming and foraging. They are fed a balanced diet to ensure proper growth and development. As the ducks mature, they may be used for breeding purposes to continue the captive population. **
