This study investigates visual plasticity in surgeonfishes by analyzing opsin gene expression across 22 species, revealing a deep phylogenetic split in visual systems that predates ecological diversification.

This study characterizes structural variation across 16 clownfish species, identifying extensive SVs and clarifying inversion events on chromosomes 18 and 9.

This study shows deep-sea fish larvae use a hybrid cone-rod photoreceptor type for vision in dim light, revealing an alternative developmental pathway for vertebrate vision.

This study shows red light reduces ALAN-induced memory impairment in clownfish, demonstrating wavelength-dependent cognitive effects of artificial light at night.

This study examines the evolution of opsin genes in ray-finned fishes, showing variation in gene numbers, co-evolution of visual and non-visual opsins, and reduced opsin repertoires in dark environments.

This study investigates the development of ultraviolet sensitivity and colour patterns in damselfishes across ontogenetic stages using UV photography, phylogenetic analysis, and gene expression data.

This paper generates the first transgenic line of the clownfish Amphiprion ocellaris using the Tol2 transposon system, achieving a 2.7% transgenesis rate and confirming germline transmission.

The paper examines how clownfish demographic responses to Pleistocene sea level changes are influenced by their host specialization, revealing resilience in generalists and bottlenecks in specialists.

This study quantifies sialic acid and its precursors in skin mucus of clownfish and damselfish to test if their absence explains protection from anemone nematocysts.

This study shows that reef fish can rapidly and reversibly adjust their retinal opsin expression and cell densities in response to short-term changes in light conditions.

The paper investigates visual system development in Holocentridae fish, showing ontogenetic shifts from photopic to scotopic vision with subfamily-specific adaptations.

The paper investigates the molecular evolution of UV-sensitive opsins in anemonefishes, identifying gene duplications and expression patterns that contribute to UV vision.

This study develops a CRISPR/Cas9 protocol for generating biallelic mutants in the anemonefish Amphiprion ocellaris, achieving high mutation efficiency and demonstrating loss-of-function phenotypes.

This study investigates the visual systems of Holocentridae fish, revealing a rod-dominated retina with multibank structures and potential for dim-light color vision.

This study examines opsin gene evolution in amphibious and terrestrial blennies, finding little sequence or expression variation despite environmental changes.

The paper investigates how social selection maintains honest signaling in cichlid fish by manipulating facial coloration and observing receiver retaliation.
