Zebrafish Color
Although innate color preference of motile organisms may provide clues to behavioral biases, it has remained a longstanding question. In this study, we investigated innate color preference of zebrafish larvae. A cross maze with different color.
Color is an important environmental factor that in multiple ways affects human and animal behavior and physiology. Widely used in neuroscience research, various experimental (animal) models may help improve our understanding of how different colors impact brain and behavioral processes. Complementing laboratory rodents, the zebrafish (Danio rerio) is rapidly emerging as an important novel.
Zebrafish Stripes as a Model for Vertebrate Colour Pattern Formation ...
Here, we ask whether zebrafish, Danio rerio, that evolved and developed in different physical environments have different color preferences, and whether these preferences impact their associative. Zebrafish, also known as Danio rerio, has captivated researchers and aquarists alike with its vibrant color patterns and genetic tractability. Among vertebrates, Zebrafish exhibit one of the most striking pigment patterns, making them a model organism for studying the genetic and cellular mechanisms underlying Danio fish pigmentation and color changes.
Baden reviews how zebrafish visual circuits extract and use spectral information from their natural surroundings to guide behaviour. He also puts these findings from fish in an evolutionary context, linking functional circuit motifs across the vertebrate tree of life up to and including humans. What is the color preference of zebrafish? While some studies on lab reared strains showed that zebrafish were attracted to shorter wavelength colors like blue and green and avoided longer wavelength colors like red and yellow 37,38, other studies demonstrated that zebrafish strongly avoided blue but were attracted to green, red and yellow colors 39.
Zebrafish Change Color for Sex | Live Science
The color pattern of the adult zebrafish is composed of a series of blue and golden horizontal stripes covering the body and the anal- as well as tail fin 7 - 10. Closely related Danio species with very similar shapes, lifestyle and geographical distribution display strikingly different adult pigment patterns 11, 12. The Zebrafish Colour Pattern The zebrafish, Danio rerio, owing its name to the striking stereotypic pattern of longitudinal blue and yellow stripes, has emerged as the model organism for colour pattern formation in vertebrates (Figure 1).
Development takes place outside the mother, allowing direct inspection at all stages. New research identifies the intricate cellular machinery that enables zebrafish to change the color of their characteristic stripes. This information is compared to findings in other vertebrates and relevance to disorders affecting color processing is discussed.
