Eusociality (Greek eu: "good/real" + "social"), the highest level of organization of animal sociality, is defined by the following characteristics: cooperative brood care (including brood care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society which are sometimes called castes. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform at least one behavior characteristic of individuals in another caste.
Eusociality exists in certain insects, crustaceans and possibly mammals. It is mostly observed and studied in the Hymenoptera (ants, bees, and wasps) and in the termites. For example, a colony has caste differences; queens and reproductive males take the roles as the sole reproducers while the soldiers and workers work together to create a living situation favorable for the brood. In addition to Hymenoptera and Isoptera, there are two known eusocial vertebrates from the order Rodentia, which includes the naked mole-rat and the Damaraland mole-rat. Some shrimps such as Synalpheus regalis are also eusocial.
Ripped down piece by piece
Old life crumbles in your hand
I feel deceased
No burn, no sickness
How surprising is okay
Don't look at me
I am shamed
I wear my letter
You piont your finger
Never good enough
Never get up
Weak like sand
And ask your tearing me down
The ache in my back
The burn in my legs
Your sight burns me
I feel no more, it said
You only die once
