It was tested whether the pajama cardinalfish Sphaeramia nematoptera (Apogonidae) could home by displacing individuals up to 250 m within and among isolated reefs. Contrary to expectations, only two of 37 (5·4%) displaced S. nematoptera returned home and another 16 (43·2%) were found to have joined other social groups and did not home after 26 months of observations; while over the same period, 94% of control S. nematoptera remained associated with home corals, demonstrating strong site…

Strong homing does not predict high site fidelity in juvenile reef fishes

It appears that some juvenile fishes may have a higher innate spatial flexibility than their strict homing drive suggests, and an increased propensity to relocate after encountering alternative reef locations while homing.

Homing Ability of Goldsinny Wrasse (Ctenolabrus rupestris)

After the discovery of delousing abilities of temperate wrasses, several wrasse species are increasingly harvested in Norway and supplied to salmonid aquafarms to combat sea lice infestations. An

High prevalence of homing behaviour among juvenile coral-reef fishes and the role of body size

A ‘sense of home’ and site attachment appear to develop early during ontogeny, especially above taxon-specific size thresholds, which suggests that spatial flexibility exists only in a brief window after settlement, with direct implications for subsequent patterns of connectivity and ecosystem function in adult reef fish populations.

How flexible are habitat specialists? Short-term space use in obligate coral-dwelling damselfishes

The spatial behaviour of obligate coral-dwellers in relation to habitat quality and KUDs (Kernel Utilisation Distributions) are documented to help explain these fishes’ apparent, unexpected resilience to habitat loss.

Site fidelity facilitates pair formation in aggregations of coral reef cardinalfish

In these cardinalfish, strong site attachment facilitates long-lasting pair bonds, as well as new pair formation when necessary, suggesting that site rather than mate fidelity is the major driver of the reproductive system.

Extra‐pair mating in a socially monogamous and paternal mouth‐brooding cardinalfish

It is argued that while pair formation contributes to group cohesion, both males and females can maximize lifetime reproductive success by taking advantage of extra‐pair mating opportunities.

The role of nocturnal fishes on coral reefs: A quantitative functional evaluation

Abstract The ecological functions of nocturnal coral reef fishes are poorly known. Yet, nocturnal resources for coral reef consumers are theoretically as abundant and productive, if not more so, than



Heterogeneity in habitat choice in cardinal fish community structure

It is shown that different groups of fishes within the coral-reef biome are affected by different assemblage structure control mechanisms, including apogonids and blennioid fishes.

Homing behaviour of rock pool blenny Parablennius parvicornis (Pisces: Blenniidae)

The homing ability of the rock pool blenny Parablennius parvicornis was studied at a rocky shore on Gran Canaria (Canary Islands, Spain). A total of 140 fish was tagged in five different rock pools

Habitat specialisation and overlap in a guild of coral reef cardinalfishes (Apogonidae)

The high level of both specialisation and overlap in habitat use suggests that the future biodiversity of cardinalfishes in Kimbe Bay could be linked to the fate of a single coral species.

Postsettlement movement patterns and homing in a coral-associated fish

This study shows that G. histrio frequently moves between corals, although this depends on the social status (juvenile, single adult, breeding pair) of the individuals, and indicates low sensitivity to habitat alteration but also limited high-quality habitats in which breeding pairs could be established.

Homing and site fidelity in the greasy grouper Epinephelus tauvina (Serranidae) within a marine protected area in coastal Kenya

Home ranges established after homing in the greasy grouper Epinephelus tauvina were stable and negatively correlated with fish size, suggesting an ontogenetic shift in home range development.

Long-distance migration and homing after displacement in the green turtle (Chelonia mydas): a satellite tracking study

Four green turtle females were tracked by satellite during their post-reproductive migration in the South China Sea. Three of them reached their feeding grounds 923–1551 km distant. During nesting

How Nemo finds home: the neuroecology of dispersal and of population connectivity in larvae of marine fishes.

Current understanding of sensory cues marine fish larvae use for orientation in the pelagic environment are reviewed and how sensory abilities of larvae develop and are used to achieve orientation are reviewed with particular emphasis on coral-reef fishes.

Diet and nocturnal foraging in cardinalfishes (Apogonidae) at One Tree Reef, Great Barrier Reef, Australia

Since apogonids feed in a range of habitats, then return to restricted resting sites during the day, they are likely to play an important role in concentrating nutrients and energy on reefs, providing localised and predictable resources for both predators and detritivore communities.
