Are Caribbean cleaning symbioses mutualistic? Costs and benefits of visiting cleaning stations to longfin damselfish
Cleaning symbioses in the marine environment have long been held to be mutualistic interactions in which cleaners glean food from the surface of their fish clients while client ectoparasite load is
Mutualism or parasitism? The variable outcome of cleaning symbioses
Spatial variation in the outcome of the cleaning relationship between Caribbean cleaning gobies and longfin damselfish over the distribution range of these species is shown, and this variation is linked to the availability of ectoparasites.
Long-Term Effects of the Cleaner Fish Labroides dimidiatus on Coral Reef Fish Communities
This is the first study to demonstrate a benefit of cleaning behaviour to client individuals, in the form of increased size, and to elucidate potential mechanisms leading to community-wide effects on the fish population.
Conspicuousness is correlated with toxicity in marine opisthobranchs
A significant correlation between conspicuousness and toxicity is found, indicating that conspicuousness acts as an honest signal when signifying level of defence and provides evidence for aposematism in opisthobranchs.
The ultimate effect of being cleaned: does ectoparasite removal have reproductive consequences for damselfish clients?
Although ectoparasite removal appears to have no direct consequence for reproduction, at least for the levels of infestations observed on the study site, it may still affect other aspects of damselfish fitness such as survival.
Indirect consequences of parental care: sex differences in ectoparasite burden and cleaner-seeking activity in longfin damselfish
Intersexual differences in territory position, proximity to and use of cleaning stations, and ectoparasite loads are indirect consequences of sex differences in reproductive-resource requirements in longfin damselfish.
In situ evidence for ectoparasites as a proximate cause of cleaning interactions in reef fish
The effect of ectoparasite load (i.e. the number of larval gnathiid isopods) on client behaviour under natural conditions is examined and corroborate recent experimental results on captive clients and are consistent with the mutualistic interpretation of cleaning symbioses.
The Evolution of Fangs, Venom, and Mimicry Systems in Blenny Fishes
It is found that fangblenny venom contains a number of toxic components that have been independently recruited into other animal venoms, some of which cause toxicity via interactions with opioid receptors, and result in a multifunctional biochemical phenotype that exerts potent hypotensive effects.
Mimicry in coral reef fish: how accurate is this deception in terms of color and luminance?
The majority of mimics closely resembled models in terms of color and luminance from a nonsubjective perspective, but fish that have potentially trichromatic visual systems with ultraviolet sensitivity had a much better capacity to discriminate between models and mimics compared with fish with midrange sensitivity or dichromatic (2 cone photoreceptors) fish.
Fish Chromatophores--From Molecular Motors to Animal Behavior.
A cross-disciplinary review of chromatophores of lower vertebrates has highlighted emerging trends in pigment cell research and identified unsolved problems for future research.
