Experts say that ants are very many kinds, like the description below,
Ants are a type of insect with a very large number of species and individuals. The number of ants on the earth's surface comprises more than 12,000 species, but only about 7600 species of 250 genus have been named and described. The greatest ant diversity is in the tropics. Ants are widely distributed all over the place except in the ocean, ranging from the Arctic region to the north to the polar regions in the south (Daly et al., 1978).
Worker ants separate the larvae into groups according to body size and age. Workers will give more attention if there is an individual that size, because usually the individual will be a queen or male ants. Separation of larvae in similarly sized groups ensures that each larva gets adequate attention and food (Anonymous, 1988).
The way ants live is remarkable in terms of how they work together to achieve a goal, so people say "unite you like ants."
