Animals are fundamentally divided into vertebrates (animals with backbones) and invertebrates (animals without backbones). This binary classification is one of the most basic ways to categorize the animal kingdom. Vertebrates include mammals, birds, reptiles, amphibians, and fish, while invertebrates comprise all other animals like insects, worms, and mollusks.

Man (humans) are vertebrates (having a backbone), omnivorous (eating both plants and animals), and mobile (not stationary). Sea anemones and jellyfish are invertebrates without backbones. Lobsters, while they do move, are also invertebrates with exoskeletons, not vertebrates. The question specifically requires an animal that meets all three criteria: vertebrate, omnivorous, and mobile.

12 years is a reasonable average lifespan for domestic cats, particularly indoor cats. Indoor cats typically live 12-18 years, while outdoor cats have much shorter lifespans (2-5 years) due to predation and accidents. The other options are unrealistic - 45 years is far too long, and 19-20 years would be exceptionally old.

12 years is a reasonable average lifespan across all dog breeds, though it varies significantly by size. Small dogs often live 10-15 years (sometimes up to 18-20), while large breeds typically live 8-12 years, and giant breeds only 6-9 years. The claimed answer represents a fair average across this wide range.

15 years is within the typical lifespan range for lions. African lions in the wild live 10-14 years on average, while in captivity they can reach 20-25 years. The term 'black Lion' is unusual as there are no naturally occurring black lions - this may be a typo or refer to a specific individual.

2 years is reasonable for mice in captivity or as pets. Wild house mice typically only live about 1 year due to predation and harsh conditions, while protected/pet mice can live 2-3 years. The claimed answer assumes a protected environment.

22 years is on the high end but possible for tigers in captivity. Wild tigers typically live only 8-10 years, while those in captivity can reach 16-20 years, with some living up to 25 years. Given the options provided (21-24), 22 years would be in captivity context. This is somewhat misleading for wild tigers.

100 years is reasonable for large tortoise species such as Galapagos tortoises, which are known to live over 100 years. Turtle lifespan varies greatly by species - small pet turtles live 20-40 years, while giant tortoises can reach 100-150+ years. Given the 100-103 year range in options, this refers to large tortoise species.

Domestic rabbits typically live 5-8 years on average, with some reaching up to 10-12 years with proper care. The option of 5 years represents a reasonable average lifespan.
