Red Coloration in an Anchialine Shrimp: Carotenoids, Genetic Variation, and Candidate Genes.

The Biological bulletin - 1 Apr 2020

Weaver Ryan J, Gonzalez Bryson K, Santos Scott R, Havird Justin C

Abstract excerpt

Red coloration is a widely distributed phenotype among animals, yet the pigmentary and genetic bases for this phenotype have been described in relatively few taxa. Here we show that the Hawaiian endemic anchialine shrimp Halocaridina rubra is red because of the accumulation of astaxanthin. Laboratory colonies of phylogenetically distinct lineages of H. rubra have colony-specific amounts of astaxanthin that are...
