From publisher blurb:
Remarkable Races is going beneath the waves in a new series called "Remarkable Races Submerged." These new racial supplements will add an aquatic flair to our beloved Remarkable Races line, transforming many of your favorite races for use with the Cerulean Seas Campaign Setting, as well as introducing a few new ones.
The second in this line (after the Sunken Relluk) is the Aquatic Anumi; water pets who have undergone a radical transformation into humanoid versions of their former selves. More than just anthropomorphic sea animals; they have an ancient secret that once made them direct representatives of the gods themselves. With this catch-all bestial race, personify your favorite animal and lead him into combat against evil!
This book expands on the material presented in the Cerulean Seas Campaign Setting, bringing you a new PC race for aquatic adventure!
