Description
The Crocate Spider Shell is a striking marine gastropod known for its distinctive, spiny appearance. The shell is robust and heavy, characterized by a flared outer lip adorned with several long, curved, finger-like processes or spines. Its exterior typically exhibits pale, whitish to light purplish-brown hues, sometimes with subtle spiral banding on the spire. A prominent feature is its vibrant orange to reddish-orange aperture, which contrasts sharply with the lighter exterior. The siphonal canal is elongated and curved. This species is a herbivore, grazing on algae in its shallow marine habitat.
