Which animals produce few eggs?

It's difficult to definitively say which animals produce "few" eggs because it depends on what you consider "few" and the context. However, we can consider some general categories:

* Mammals: Most mammals give birth to live young rather than laying eggs. Those that do lay eggs, like monotremes (e.g., platypus, echidna), lay very few eggs, usually just one or two.

* Birds: While some birds lay many eggs, others lay very few. For example, birds of prey, like eagles and hawks, usually lay only 1-3 eggs per clutch. Some seabirds, like albatrosses, also lay only one egg at a time.

* Reptiles: Some reptiles, like snakes and lizards, can lay many eggs. However, some, like turtles and tortoises, lay relatively few, typically around 5-10 eggs.

* Amphibians: Amphibians generally lay a large number of eggs. However, some species, like the poison dart frog, lay just a few eggs, typically attached to leaves or other surfaces.

Factors influencing the number of eggs:

* Environmental conditions: Animals living in harsh environments, like cold climates or areas with limited resources, tend to lay fewer eggs.

* Parental care: Species with a high degree of parental care, like birds, often lay fewer eggs, as they can invest more energy into raising a smaller number of offspring.

* Predator pressure: Animals that are preyed upon often lay more eggs, increasing the chances of at least some offspring surviving.

Therefore, it's more about the specific species and its ecological niche than a general categorization.
