The Early Development of the Blue-Eye Cichlid, Cryptoheros spilurus (Cichliformes: Cichlidae). [PDF]

Evol Dev
We document the early development of Cryptoheros spilurus, highlighting rapid cranial differentiation, sensory organ formation, and fin development. Ontogenetic allometry and ultrastructural traits reveal functional adaptations for early foraging and locomotion, offering insights into ecological success and the developmental basis of cichlid ...

The association between neural crest‐derived glia and melanocyte lineages throughout development and disease

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common

Pigment-dispersing activities and cortisol-releasing activities of melanocortins and their receptors in xanthophores and head kidneys of the goldfish Carassius auratus [PDF]

, 2011
The five subtypes of melanocortin receptors (MCRs) mediate the functions of α-melanocyte-stimulating hormone (α-MSH) and adrenocorticotropic hormone (ACTH). In fish, these hormones are involved in pigment dispersion and cortisol release, respectively.

Resonant third harmonic generation in biological pigments [PDF]

APL Photonics
Third harmonic generation (THG) microscopy provides label-free structural contrast of biological tissues. While the THG process can be enhanced by electronic transitions in absorbing molecules, knowledge of the third-order nonlinear properties of ...

MIT/TFE family transcription factors, Mitf and Tfec, redundantly promote pigment cell differentiation and retinal epithelium pigmentation in teleosts

Developmental Dynamics, EarlyView.
Abstract Background Transcription factors of the MIT/TFE family—mitfa, mitfb, and tfec—play essential roles in specifying pigment cells derived from neural crest cells in vertebrates. In teleosts, which possess multiple pigment cell types, these factors exhibit partially redundant but largely distinct functions across different pigment lineages.

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

Control Strategies in Guanine Biocrystallization

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Biological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...

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.
