Echinodermata

Vedclass · Answer

(B) $1$. Adults of the phylum $Echinodermata$ exhibit radial symmetry (specifically pentamerous radial symmetry).$2$. $Echinoderms$ are $deuterostomes$,meaning the $blastopore$ (the first opening in the embryo) develops into the $anus$,while the $mouth$ forms secondarily.$3$. $Cnidarians$ and $Ctenophores$ also exhibit radial symmetry,but they are not $deuterostomes$ and do not possess a true $anus$ (they have an incomplete digestive tract).$4$. Therefore,the correct answer is $Echinodermata$.
