SynopsisStomach contents of the clingfish Diademichthys lineatus, 10–56 mm standard length, revealed changes in food habits with growth and sexual differences. Soon after settlement, D. lineatus obtained food from their host sea urchin (genus Diadema) and other associated symbionts. They became less dependent on the host with growth. The juveniles ate pedicellariae and sphaeridia of the host and commensal copepods, whereas the adult fish ate burrowing bivalves in corals as well as tube feet of… 
Fish-egg predation by the small clingfish Pherallodichthys meshimaensis(Gobiesocidae) on the shallow reefs of Kuchierabu-jima Island, southern Japan
Predation of demersal fish eggs by the clingfish Pherallodichthys meshimaensis on the shallow reefs of Kuchierabu-jima Island, southern Japan may change its feeding habits when growing to an obligate fish-egg eater targeting demeral egg spawners.
Partial Filial Cannibalism Enhances Initial Body Condition and Size in Paternal Care Fish with Strong Male—Male Competition
It is suggested that the ability to defend a nest will ensure a longer care-period, and thus, a higher reproductive output, in this fish, and the first documented evidence that filial cannibalism enhances the initial body condition of cannibals is reported.
Community-wide consequences of sexual dimorphism: evidence from nectar microbes in dioecious plants.
Evidence is provided that sexual dimorphism can have large effects on the structure of host-associated communities in animals and plants through differences in how animals and microbes altered the chemical characteristics of nectar that limited microbial growth.

Use of the sea urchin Diadema antillarum (Echinodermata, Echinoidea) as a shelter for non-cryptobenthic juvenile reef fishes
The commensal behavior of juveniles of two non-cryptobenthic reef fishes with the sea urchin Diadema antillarum on sandstone reefs in Northeastern Brazil is described to raise the assumption that D. antillaru may provide an alternative source of shelter and therefore influence microhabitat complexity, particularly, for juvenile reef fishes.

The effect of sea urchins as biogenic structures on the local abundance of a temperate reef fish
It is suggested that habitat selection at the time of settlement, small-scale migration of fish after settlement, and differential survival relative to the presence of sea urchins contribute to the formation and maintenance of the association between L. dalli and C. coronatus.
Description of a New Genus and Two New Species of Indo-Pacific Clingfishes (Gobiesocidae: Diademichthyinae) with Redescription and Reassignment of Two Species Previously Assigned to Lepadichthys Waite, 1904
A new genus and two new species of Indo-Pacific clingfishes are described in this study and two additional species previously assigned to Lepadichthys are transferred to Flabellicauda, new genus, including F. alleni, newspecies, and F. cometes, new species.
Commensalism between Juvenile Cusk Eels and Pancake Urchins on Western North Atlantic Seamounts
It is suggested that such associations provide juvenile cusk eels with shelter from predators or flow (or both) and access to prey far from other forms of refugia.
Ontogenetic Shifts in Patterns of Microhabitat Utilization in the Small-headed Clingfish, Apletodon Dentatus (Gobiesocidae)
There was a differential utilization of the microhabitats, with small juveniles recruiting to algal turfs, intermediate individuals found in association with the sea urchins Paracentrotus lividus and Sphaerechinus granularis and larger fish occurring mainly in boulders.


Social behavior and coloration changes in painted greenling, Oxylebius pictus (Pisces: Hexagrammidae)
Sexual color patterns are discussed in relation to niche partitioning and agonistic and epigamic sexual selection and Behavioral modification of sexual dichromatisms in 0.
Association between the Echinoid Evechinus chloroticus (Val.) and the Clingfish Dellichthys morelandi Briggs
To investigate the possible role of visual stimuli in attracting Dellichthys to Evechimts, an oblong clear perspex tray divided into three equa! parts was used and a Y-maze perspex olfactometer was used through which unfiltered sea water flowed continuously from a constant ~ead a~ about 400 cc per minute.
Male mating success, sexual size dimorphism, and site fidelity in two species of Malacoctenus (Labrisomidae)
The results suggest that the evolution of the differences in site fidelity and sexual size dimorphism between these two species may be due to sexual selection acting differentially inThese two species.

An adequate mammalian model will have to include another set of factors which oppose the evolution of polygyny by increasing the spacing or mobility of females, and explain why sexual dimorphism has evolved more frequently in large mammals than in small ones.
A New Genus and Species of Clingfish from the Western Pacific
A small, new species of clingfish from the Bismarck Archipelago and the Fiji Islands is described. It belongs to a new genus that is apparently specialized for a commensal relationship with certain
