Due to their wide distribution, these mollusks are able to survive in most temperatures and sea levels.
These extinct mollusks are recognized by the distinct spiral shape of their shells and are closely related to octopuses, squid, and cuttlefish.
Whelks is the general name given to a variety of sea snails, many of which are part of the Buccinidae family (true whelks).
Wentletraps, also called staircase shells and ladder shells, are known as such due to their intricate geometric shell architecture.

Limpets have a conical disk-shaped shell and over 100 rows of teeth. However, these gastropods only utilize the ten outermost rows for feeding. These aquatic snails use their strong muscular foot to form a solid bond to rocks, making it difficult for predators to attack or pry them off.
