eucarida meaning in Hindi
eucarida sentence in HindiExamples
- One study supports the monophyly of Eucarida ( with basal Mysida ), another groups Euphausiacea with Mysida ( the Schizopoda ),
- Later, William Thomas Calman ( 1904 ) ranked the Mysidacea in the superorder Peracarida and euphausiids in the superorder Eucarida, although even up to the 1930s the order Schizopoda was advocated.
- Molecular studies have not unambiguously grouped them, possibly due to the paucity of key rare species such as " Bentheuphausia amblyops " in krill and " Amphionides reynaudii " in Eucarida.
- William T . Calman in 1904 and 1909 described these common morphological features and introduced the major taxonomic subdivisions of the Malacostraca which are still in use today : he divided the Malacostraca in two subclasses the Phyllocarida and the Eumalacostraca, which is further subdivided into four superorders : Eucarida, Peracarida, Hoplocarida and Syncarida.
- The members of the Mysida and the Lophogastrida have several common features : they are shrimp-like with compound stalked eyes and have a carapace which covers most of the thorax but does not fuse with the last four thoracic segments ( as instead is seen in the Eucarida ), they possess well-developed thoracopods ( for swimming ) and tail fan, they also have similar behaviour ( swarming ) and foregut structure; or made them basal to a eucarid subtree ( paraphyletic ).
