Scallops

Scallops come in all sorts of shapes, sizes, and colors. Typically, a scallop can live up to 20 years. Scallops enjoy saltwater environments and like to attach to beds of seagrass or rocks. Their crazy relative is the oyster!

Fighting Conch

The Conch shell is rumored to carry the sound of the crashing waves as one puts it up to his or her ear! Fun fact, what you are truly hearing is the sound of your own pulse. Conchs have a very interesting way of getting around. As opposed to swimming, they throw their bodies forward using their strong legs to lift themselves up. Conchs are very social creatures and like to congregate.

Lightning Whelk

This species of shell likes to steer clear of Sea Turtles and Blue Crabs because if they aren’t careful, they might be eaten! Lightning Whelks are a particular type of shell that require an optimum water temperature of 77-82 degrees Fahrenheit, or else they will slow their feeding rates and crawl at a much slower speed. This type of shell is easy to recognize because of the brownish orange stripes shaped like lightning bolts on young shells, and the spiral that grows leftwards on adults.
