Laboratory observations on a field-collected colony of 40 Heterocephalus have shown that only a single female breeds. The remaining individuals constitute two or three castes, each containing both sexes and distinguishable by size differences and the tasks they perform. These features, together with long life-spans, overlap of generations, cooperative brood care, and possible age polyethism provide parallels with the eusocial insects. 
Mammalian eusociality: a family affair.
Eusociality has evolved independently in two genera of bathyergid mole-rats — but occurs in no other subterranean mammal
Differences in colony cohesion, ethology and the hormonal profiles of non-reproductive animals suggests that eusociality evolved along different pathways in these two phylogenetically divergent genera of the Bathyergidae.
Benefits of cooperation in captive Damaraland mole-rats
Although the social mole-rats are commonly classified as eusocial breeders on the grounds that groups include a single breeding female (the "queen") and a number of nonbreeding individuals ("helper

Eusociality in a coral-reef shrimp
Ecological similarities among mole-rats, termites and these sponge-dwelling shrimp, all of which are diploid animals, strengthen arguments that eusociality is favoured by gradual metamorphosis, parental care, and occupation of protected, expansible niches.
Variability of space-use patterns in a free living eusocial rodent, Ansell’s mole-rat indicates age-based rather than caste polyethism
An attempt to detect polyethism in the free-living Ansell’s mole-rat (Fukomys anselli) as differences in individuals’ space-use patterns was made.
Why Are There No Reports of Eusocial Marine Crustaceans
The goal is to point out the possibility of the presence of eusocial marine forms, and to urge marine biologists to look for them.
Behavioural interference among eusocial naked mole rats during work
The data support the hypothesis that tail-tugging was more likely to occur when the actor and recipient were working than when they were not, and suggest that there is disagreement and conflict regards the opportunity to work among colony members in this eusocial mammal.
Social Behavior in Naked Mole-Rats: Individual Differences in Phenotype and Proximate Mechanisms of Mammalian Eusociality.
Naked mole-rats provide the opportunity to examine the proximate mechanisms controlling individual differences in social behavior, shedding light on how mammals live in complex social groups.

Olfactory Communication in Mammals
Olfactory communication is defined as the process whereby a chemical signal is generated by a presumptive sender and transmitted to a presumptive receiver who by means of adequate receptors can identify, integrate, and respond (either be­ haviorally or physiologically) to the signal.
