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] Due to their
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.
