peracarida मीनिंग इन हिंदी

उदाहरण वाक्य

1. They differ from other species within the superorder Peracarida by featuring statocysts on their uropods ( located on the last abdominal segment ).
2. In the Isopoda and Tanaidacea ( superorder Peracarida ), the last abdominal body segment is fused with the telson, forming a " pleotelson ".
3. The remaining Peracarida orders are the cryptic and either moderately abundant, Cumacea and Tanaidacea, or are extremely rare and relictual, Mictacea, Spelaeogriphacea, and Thermosbaenacea.
4. 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.
5. 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.
6. The Thermosbaenacea is a group of 11 species found in hot springs, caves and groundwater that has the peculiarity that its brooding pouch is formed by its extended carapace and not by modified thoracopod endites as occurs in the remaining peracarids, for this reason some authors have removed this group from the Peracarida and placed it in its own superorder, the Pancarida, basal to the Pericarida.
7. Molecular studies by Jarman " et al . " ( 2000 ), Spears " et al . " ( 2005 ) and Meland & Willassen ( 2007 ) ( which was derived from Spears " et al . " ( 2005 ) by adding 22 mysidacean taxa to those 26 taxa ) suggest a phylogeny with some elements similar to that proposed by Richter & Scholtz ( 2001 ), but disprove the monophyly of both the Edriophthalma and the Mysidacea and do not possess a basal eumalacostracan taxa or a basal peracarid taxa ( the Hoplocarida and the Syncarida, respectively in ) : The Amphipoda ( with Spleogriphacea ) form a clade with the Lophogastrida, the Isopoda are in a derived clade with the Cumacea and Tanaidacea, while most importantly the Mysida in all three analyses falls basal to the non-Peracarida subtree, which however has a limited morphological support ( Poore, 2005 ).
