Vedclass · Answer

(B) The diaphragm is not a characteristic feature of all chordates. In mammals,the body cavity is internally divided into two portions,the thorax and the abdomen,by a transverse muscular partition called the diaphragm. While an incomplete diaphragm is present in crocodiles,it is not a defining feature of the phylum Chordata as a whole. In contrast,the presence of a coelom,a dorsal nerve cord,and pharyngeal gill slits (at some stage of development) are fundamental diagnostic characteristics of all chordates.
