Abstract. The sponge-dwelling shrimp Synalpheusregalis and several congeners exhibit monogynous, eusocial colony structures, and field data suggest that these social species may have a competitive advantage in crowded environments. We explored mechanisms of colony defense, a likely contributor to such a social advantage, by measuring responses of resident shrimp to conspecific and heterospecific intruders in experimental nests. To test for behavioral differentiation among classes of individuals… 

Allometry of reproduction, weapon size, and colony size in social shrimp: A comparative analysis of four eusocial species in genus Synalpheus

Bivariate regressions and structural equation modeling were used to characterize relationships between queen fecundity, size of the major chela, and colony size, shedding light on the relationship between individual success and social organization in sponge-dwelling shrimp.

Influence of sociality on allometric growth and morphological differentiation in sponge-dwelling alpheid shrimp

Shrimp are similar to other eusocial animals in the morphological differentiation between breeders and nonbreeders, and in the indication that some larger nonbreingers might contribute more to defence than others.

Allometry of individual reproduction and defense in eusocial colonies: A comparative approach to trade-offs in social sponge-dwelling Synalpheus shrimps

These results suggest that in less cooperative species, intra-colony conflict selects for queen retention of weapons that have significant costs to fecundity, while reproducing females from highly eusocial species, i.e., those with a single queen, have been able to reduce the cost of weapons as a result of protection by other colony members.

Behavioral traits and territoriality in the symbiotic scaleworm Ophthalmonoe pettiboneae

It is suggested that a marine symbiotic invertebrate may control a territory extending beyond its host, even including neighboring hosts, in what is the first report of such a complex symbiotic behavior for an annelid polychaete.

Social Control of Reproduction and Breeding Monopolization in the Eusocial Snapping Shrimp Synalpheus elizabethae

It is shown that workers in Synalpheus elizabethae are reproductively totipotent and that female—but not male—gonadal development and mating are mediated by the presence of a queen, apparently without physical aggression.

Sex and social status affect territorial defence in a cooperatively breeding cichlid fish, Neolamprologus savoryi

It was found that dominant male and dominant female N. savoryi were both highly aggressive towards heterospecific predators and towards same-sex conspecific rivals and both dominant males and females were less aggressive towards opposite-sex Conspecific opponents, with the relative reduction in aggression being most pronounced in males.

Comparative Social Behavior

Mating System of the Snapping Shrimp Synalpheus brevicarpus (Caridea, Alpheidae) Inhabiting Sponges Dysidea sp. (Demospongiae)

The results indicate that S. brevicarpus is a pair-living shrimp with a monogamous social and mating system that may also guard spaces or areas within its sponge host.

Social organization in a flatworm: trematode parasites form soldier and reproductive castes

The division of labour described here for trematodes is strongly analogous to that characterizing other social systems with a soldier caste, and indicates the general importance of ecological factors in influencing the evolution of social behaviour.

Kin structure, ecology and the evolution of social organization in shrimp: a comparative analysis

It is shown that eusocial species are more abundant, occupy more sponges and have broader host ranges than non-social sister species, and that these patterns are robust to correction for the generally smaller body sizes of eussocial species.



Colony Structure of the Social Snapping Shrimp Synalpheus Filidigitus in Belize

Observations suggest that, as previously shown for the eusocial S. regalis, the colony is a close-kin group consisting mainly of the queen's philopatric offspring, and that S. filidigitus may be eussocial according to the traditional definition.

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.


Data from the phylogeny of 13 species of sponge‐dwelling shrimps (Synalpheus) are consistent with hypotheses that cooperative social groups enjoy a competitive advantage over less organized groups or individuals, and that enemy pressure is of central importance in the evolution of animal sociality.

On the frequency of eusociality in snapping shrimps (Decapoda : Alpheidae), with description of a second eusocial species

New collections, observations made by students of this genus over the last century, suggest that several sponge-dwelling Synalpheus species similarly exhibit overlapping generations and monopolization of reproduction by a few individuals, and thus that these species may also be eusocial according to classical entomological criteria.

Species boundaries, specialization, and the radiation of sponge-dwelling alpheid shrimp

Diversity of Synalpheus, which is already among the most species-rich crustacean genera, is probably several times higher than currently recognized, and species of sponge-dwellingsynalpheus are highly host-specific, with related species distinctly segregated among hosts.

Aspects of the aggressive and sexual behaviour of alpheus heterochaelis say

Alpheus heterochaelis were collected near Beaufort, N.C. and the intensity of the sound produced by the large claw is positively correlated with claw size, which offers potential cues to the size of an opponent.

Symmetric fights as a measure of escalation potential in a symbiotic, territorial snapping shrimp

If injuries are an accurate measure of the most important costs associated with fighting, then these results indicate that short contests are not necessarily the least costly, and that females can be more aggressive than males, as measured by escalation potential, in sexually selected species.

Mating behaviour and spermatophore transfer in the shrimp Heptacarpus pictus (Stimpson) (Decapoda: Caridea: Hippolytidae)

Heptacarpus pictus, a small caridean shrimp inhabiting the low intertidal of southern and Baja California, breeds during the winter, spring, and summer months, with fish predation as the most likely source of mortality.

Colony Size and Individual Fitness in the Social Spider Anelosimus eximius

Investigation of colonies of the social spider Anelosimus eximius found females in colonies containing between 23–107 females had india significantly higher lifetime reproductive success than females in smaller colonies, and Selection, therefore, should favor group living and itermediate colony sizes in this social spider.

Protandrous hermaphroditism in the tropical shrimp Athanas indicus (Decapoda : Caridea), a symbiont of sea urchins

The occurrence of protandrous hermaphroditism is demonstrated in the alpheid shrimp Athanas indicus (Coutiere), a species which lives in symbiosis with the sea urchin Echinometra mathaei in Indo-Pacific coral systems, suggesting that the smallest male in a group must exhibit great plasticity in his behavior to achieve reproductive output.
