Chthamalus
Encyclopedia
Chthamalus is a genus of barnacle
s that is found along almost all coasts of the northern hemisphere
, as well as many regions in the southern hemisphere
. These small barnacles have been studied in part because of the taxonomic
confusion over a group of species that, by and large, are morphologically
and ecologically quite similar. In recent years, molecular techniques have identified a number of cryptic species that have been subsequently confirmed by taxonomists using morphological measurements. Most recently the genus has been shown to be paraphyletic, with the genus Microeuraphia nested within Chthamalus.
Barnacle
A barnacle is a type of arthropod belonging to infraclass Cirripedia in the subphylum Crustacea, and is hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. They are sessile suspension feeders, and have...
