Thermosbaenacea
Order of crustaceans
Thermosbaenacea is a group of crustaceans that live in thermal springs in fresh water , brackish water and anchialine habitats . They have occasionally been treated as a distinct superorder (Pancarida ), but are generally considered to belong to the Peracarida .[ 1] troglobitic lifestyle, thermosbaenaceans lack visual pigments and are therefore blind .
The current distribution of some genera tallies well with the Miocene extent of the Tethys Sea , and it is assumed that the extant taxa are derived from ancestors that lived in open marine habitats. Elsewhere, the distribution is consistent with the break-up of Pangaea .[ 2]
The developing embryos are carried by the adult under its carapace until hatching.[ 3]
