Chiragra Spider Conch Seashell (Lambis chiragra)

The Lambis Chiragra shell, like most spider conchs, is a thick seashell with fingerlike projections extending outward. The female seashell's opening is pale pink and the two shoulder "fingers" are larger than the others. The male seashell's "fingers" are all about the same, but the opening is more brightly colored.
