The spider conch maxes out at almost a foot in shell length but averages a – still impressive- 7 inches when full grown. In the wild, these sea snails are found in shallow waters like tidal areas or areas of rubble around coral up to about 5 meters of depth. They can also be found in mangrove flats feeding mainly on algae. This species is almost solely a herbivore and will likely need supplementation of veggies if added into a new or small tank.
This conch has a large, heavy shell with finger-like protrusions on the edge that can be used to identify males from females in some cases. The males have shorter, stumpier protrusions than the females tend to have toward the posterior end of the shell.
