  10. .3.(d): Gambusia is a species of freshwater fish. It is remarkably hardy, surviving in waters of very low oxygen saturations, high salinities and high temperatures. For these reasons, this species may now be the most widespread freshwater fish in the world having being introduced as a biocontrol in certain countries to control mosquitoes. It feeds on larval and pupal stages of mosquitoes.


  11. 5. (c): The diagnostic characters of chordates are notochord. dorsal hollow nerve cord, pharyngeal slits and post anal tail. Tail is the part of the body behind the cloacal or anal opening. It contains skeletal elements, muscles, blood vessels and nerves but no viscera. It provides much of propulsive force in aquatic species. The tail is reduced or absent in the adults of some chordates.


  12. Phylum Class Subclass - Hydrozoa Scyphozoa Cubozoa Anthozoa ( Octocorallia/ Alcyonaria Hexacorallia/ Zoantharia
