For example,\u00a0all isopods have two pairs of antennae, compound eyes, and\u00a0four sets of jaws.<\/li>\n<li>The body of all isopods\u00a0consists of seven segments, each\u00a0with its own pair of walking legs.<\/li>\n<li>Isopods have a\u00a0short abdominal section\u00a0composed of six segments,\u00a0called \u201cpleons,\u201d and one or more of these segments is\u00a0fused into a tail section.<\/li>\n<li>Each pleon has a set of biramous (branching in two) limbs called \u201cpleopods\u201d that are used for swimming and respiration.<\/li>\n<li>About\u00a0half of the known species of isopods\u00a0live in the ocean.

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:\/\/phys.org\/news\/2024-01-deep-sea-crustacean-bahamas.html\" target=\"_blank\" rel=\"nofollow noopener\"><u>New deep-sea crustacean discovered in Bahamas<\/u><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Isopods are an order of invertebrates (animals without backbones) that belong to the greater crustacean group of animals, which includes crabs and shrimp.<\/p>\n","protected":false},"author":5,"featured_media":19496,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-19495","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\/19495","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=19495"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/19495\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/19496"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=19495"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=19495"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=19495"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
