The following is a list of tautonyms: zoological names of species consisting of two identical words (the generic name and the specific name have the same spelling). Such names are allowed in zoology, but not in botany, where the two parts of the name of a species must differ (though differences as small as one letter are permitted, as in cumin, Cuminum cyminum).

An example of a simple Deuterostome containing a hydrostatic skeleton would be Enteropneusta, with the common name of acorn worm. This organism is classified as a Hemichordate, and they are marine worms that use their hydrostatic skeleton to tunnel and anchor themselves into the ground. This can be used for locomotion, but also can aid in the ...
