For example, all isopods have\u00a0two pairs of antennae,\u00a0compound eyes, and\u00a0four sets of jaws.<\/li>\n<li>The body of all isopods\u00a0consists of seven segments, each with its\u00a0own pair of walking legs.<\/li>\n<li>Isopods have a\u00a0short abdominal section composed of\u00a0six segments,\u00a0called \u201cpleons,\u201d and\u00a0one or more of these segments is\u00a0fused into a tail section.<\/li>\n<li>About half\u00a0of the\u00a0known species of isopods\u00a0live in the ocean. Others live in coastal and shelf waters, moving around on the seafloor or living in plants.<\/li>\n<li>Most are free-living, but\u00a0a number of marine species are parasitic on other animals.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<hr \/>\n<h3>Q1) What are crustaceans?\u00a0<\/h3>\n<p>Crustaceans (make up a very large group of the Arthropods which include the crabs, lobsters, crayfish, shrimp, krill, barnacles, brine shrimp, copepods, ostracods and mantis shrimp. They are invertebrates with a hard exoskeleton (carapace), a segmented body that is bilaterally symmetrical, more than four pairs of jointed appendages. Crustaceans are found in a wide range of habitats &#8211; most are free-living freshwater or marine animals, but some are terrestrial (e.g. woodlice), some are parasitic (e.g. fish lice) and some do not move (e.g. barnacles)<\/p>\n<p><strong>Source:<\/strong> <a href=\"https:\/\/www.thehindu.com\/sci-tech\/energy-and-environment\/new-species-of-deep-sea-isopod-discovered-off-kollam-coast-named-after-isro\/article67973305.ece\" target=\"_blank\" rel=\"nofollow noopener\"><u>New species of deep-sea isopod discovered off Kollam named after ISRO<\/u><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Brucethoa isro is a new species of deep-sea isopod discovered off the Kollam coast, Kerala.<\/p>\n","protected":false},"author":5,"featured_media":21720,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-21719","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/21719","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=21719"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/21719\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/21720"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=21719"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=21719"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=21719"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
