Early life history of the Korean seahorse, Hippocampus haema: Evidence for direct settlement and ontogenetic shifts in snout morphology

Journal of Fish Biology, EarlyView.
Abstract Early life‐history traits of seahorses are closely linked to juvenile survival, dispersal potential and the onset of substrate attachment; however, detailed stage‐resolved descriptions remain limited for many Hippocampus species. This study examined reproductive behaviour and early ontogenetic development of the Korean seahorse, Hippocampus ...

A chemical genomic approach identifies matrix metalloptroteinases as playing an essential and specific role in Xenopus melanophore migration [PDF]

, 2009
SummaryTo dissect the function of matrix metalloproteinases (MMPs) involved in cellular migration in vivo, we undertook both a forward chemical genomic screen and a functional approach to discover modulators of melanophore (pigment cell) migration in ...

Embryonic and larval development of the endangered Chiapas killifish Tlaloc hildebrandi (Cyprinodontiformes: Profundulidae)

Journal of Fish Biology, EarlyView.
Abstract The early ontogeny of endemic freshwater fishes provides essential baseline biological information for conservation and management, particularly in species with restricted distributions and high vulnerability to habitat degradation, environmental change and population decline. This study presents the first detailed description of embryonic and

New Record of Sillago sinica (Pisces: Sillaginidae) in Korean Waters, and Re-identification of Sillago parvisquamis Previously Reported from Korea as S. sinica [PDF]

Animal Systematics, Evolution and Diversity, 2013
A single specimen of the genus Sillago, collected from Gwangyang, Korea, in May 2009, is characterized by XI first dorsal fin spines, 3 or 4 rows of melanophore pattern along the second dorsal fin membrane, and a darkish posterior margin of the caudal ...

Spot the difference: Turbidity‐driven plasticity and variation in spotted grunter (Pomadasys commersonnii) spot patterns

Journal of Fish Biology, EarlyView.
Abstract Animal body markings such as spots, stripes and patterns play important roles in camouflage and visual communication. This study investigated phenotypic plasticity in the spot patterns of spotted grunter Pomadasys commersonnii, an estuarine‐dependent haemulid species.

Development of Digital Techniques for Analysis of Hormone Regulation of Melanophore Activity in Red Drum [PDF]

, 2008
Melanophores are pigment bearing cells, which have been used as a practical method to demonstrate mechanisms of hormone interaction. A current teaching laboratory has been restructured in order to increase student participation, provide tangible results,

Individual identification of inbred medaka based on characteristic melanophore spot patterns on the head

Scientific Reports, 2023
With disease progression, individual differences appear, even in an animal disease model with genetic homogeneity. Therefore, non-invasive long term observation and individual identification is desirable for late-onset diseases.

Hierarchical Assembly as a Design Principle: Structure–Property Relationships Linking Biological Architectures to Functional Aggregate Materials

Aggregate, Volume 7, Issue 9, September 2026.
Biological function arises from aggregates rather than from molecules. Comparing biomimetic systems on a common basis reveals three transferable design rules governing hierarchical assembly, interfacial gradients, and stimulus‐coupled anisotropy, and identifies self‐healing and single‐step multiscale integration as properties that do not transfer to ...

It's not easy being green: Comparing typical skin colouration among amphibians with colour abnormalities associated with chromatophore deficits

Ecology and Evolution
Amphibians can obtain their colour from a combination of several different pigment and light reflecting cell types called chromatophores, with defects in one or several of the cells leading to colour abnormalities. There is a need for better recording of

Evolutionary Reorganization of Transcriptomic Architecture Across a UVB Tolerance Gradient in Fish

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Environmental stress can drive adaptation through changes in transcriptomic organization. Across a UVB tolerance gradient in fish, adaptive responses were associated with increasingly coordinated and functionally specialized transcriptomic networks built upon a conserved functional background.
