Like most spider conchs, the Chiragra Spider Conch has a thick shell with six long, curved fingerlike projections jutting outward. This is a species of very large sea snail that lives in shallow waters among coral reefs. On females of the species, the shell opening is pale pink, and the two shoulder “fingers” are larger than the others. The males’ “fingers” are about the same size, but the opening is more brightly colored.
