'''Хордати''' ({{јез-лат|Chordata}}) су тип [[деутеростомије|деутеростомних]] [[животиње|животиња]]. За најтипичније савремене представнике узимају се [[кичмењаци]]. Хордати припадају [[Раздео|разделу]] -{''Chordata''}-; chordates possess a [[notochord]], a hollow [[dorsal nerve cord]], [[pharyngeal slit]]s, an [[endostyle]], and a post-anal [[tail]], for at least some period of their life cycle. Chordates are [[deuterostome]]s, as during the embryo development stage the anus forms before the mouth. They are also [[bilateral symmetry|bilaterally symmetric]] [[coelom]]ates with [[Metameric|metameric segmentation]] and a [[circulatory system]]. In the case of [[vertebrate]] chordates, the notochord is usually replaced by a [[vertebral column]] during development.
 
Taxonomically, the phylum includes the following subphyla: the [[vertebrate|Vertebrata]], which includes [[fish]], [[amphibian]]s, [[reptile]]s, [[bird]]s, and [[mammal]]s; the [[Tunicate|Tunicata]], which includes [[salp]]s and [[sea squirt]]s; and the [[Cephalochordate|Cephalochordata]], which include the [[lancelet]]s. There are also additional extinct taxa such as the [[Vetulicolia]]. The Vertebrata are sometimes considered as a subgroup of the clade [[Craniate|Craniata]], consisting of chordates with a [[skull]]; the Craniata and Tunicata compose the clade Olfactores.replkm

Of the more than 65,000 living species of chordates, about half are bony fish of the superclass [[Osteichthyes]]. The world's largest and fastest animals, the [[blue whale]] and [[peregrine falcon]] respectively, are chordates, as are [[human]]s. Fossil chordates are known from at least as early as the [[Cambrian explosion]].
