Being red, blue and green: the genetic basis of coloration differences in the strawberry poison frog (Oophaga pumilio)

open access: yesBMC Genomics, 2020
Background Animal coloration is usually an adaptive attribute, under strong local selection pressures and often diversified among species or populations.

Individual identification of bony fishes using unique body markings: Implications and applications

open access: yesJournal of Fish Biology, Volume 107, Issue 6, Page 1852-1867, December 2025.
Abstract The natural variation in animal body markings, such as spots, stripes and blotches, offers a powerful tool for researchers, conservationists, citizen scientists and resource managers to distinguish specific individuals within species. By building libraries of photo‐identified individuals, we can track and differentiate individuals over time ...

Nature‐inspired hierarchical materials

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 11, November 2025.
Nature serves as a wonderful school for materials science, demonstrating how biological organisms craft hierarchical structures and multifunctional properties using limited, locally available resources. This process addresses complex design challenges while promoting sustainability.

Heterotypic interactions regulate cell shape and density during color pattern formation in zebrafish

open access: yesBiology Open, 2016
The conspicuous striped coloration of zebrafish is produced by cell-cell interactions among three different types of chromatophores: black melanophores, orange/yellow xanthophores and silvery/blue iridophores.

Muscle opacity (mo), a new mutant gene in Xenopus laevis, linked to the rusty locus [PDF]

open access: yes, 2017
A new developmental mutant is described in Xenopus laevis (Amphibia, Anura): muscle opacity (mo). Homozygotes die at larval stage 48. The underlying defect, visible at stage 47, is a degeneration of cephalic musculature.

Synthetic Chromatophores for Color and Pattern Morphing Skins

open access: yesAdvanced Materials, Volume 37, Issue 35, September 4, 2025.
Cephalopods use chromatophore organs (muscle‐actuated pigment sacs) to alter their skin color and pattern. Synthetic chromatophores, which closely mimic the mechano‐optical process found in cephalopods using stimuli‐responsive microscale hydrogel actuators, are reported.

Zebrafish adult pigment stem cells are multipotent and form pigment cells by a progressive fate restriction process:Clonal analysis identifies shared origin of all pigment cell types [PDF]

open access: yes, 2017
Skin pigment pattern formation is a paradigmatic example of pattern formation. In zebrafish, the adult body stripes are generated by coordinated rearrangement of three distinct pigment cell-types, black melanocytes, shiny iridophores and yellow ...

Development and Characterization of a Sardine Scale‐Chitosan Biomaterial: In Vivo Evaluation for Bone Regeneration in a Rat Osteoporosis Model

open access: yesJournal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 113, Issue 9, September 2025.
ABSTRACT The development of functional materials for osteoporosis is essential for effective bone remodeling. In this context, the extraction of biocompatible implantable biomaterials from bio‐waste emerges as a valuable strategy, addressing both environmental challenges and promoting human health.
