Multiple egg defenses arose early in the history of apple snails preceding carotenoid-bound perivitellins

Apple snails ( Pomacea) lay egg masses above the waterline that are protected by complex biochemical defenses, yet current knowledge is largely derived from invasive and phylogenetically derived clades. Here, we investigate the early evolution of these defenses characterizing the eggs of Pomacea sordida , a repre...
