Galeodea is a genus of large sea snails, marine gastropod mollusks in the subfamily Cassinae of the family Cassidae. [1]
This genus is known in the fossil record from the Cretaceous period to the Quaternary period (age range: from 99.7 to 0.126 million years ago.). Fossil shells within this genus have been found all over the world. [2]
Species within the genus Galeodea include:
The Tonnidae are a family of medium-sized to very large sea snails, known as the tun shells. These are marine gastropod molluscs in the clade Littorinimorpha. The name tun refers to the snails' shell shape, which resembles wine casks known as "tuns". While thin, the shells are also strong and lack opercula. They are found in all tropical seas, where they inhabit sandy areas. During the day, they bury themselves in the substrate, emerging at night to feed on echinoderms, crustaceans, and bivalves. Some larger species also capture fish, using their expandable probosces to swallow them whole. Females lay rows of eggs that become free-swimming larvae for several months before settling to the bottom.
