Mouth is located ventrally

Vedclass · Answer

(A) The class $Chondrichthyes$ (cartilaginous fishes) exhibits several distinct characteristics:$1$. Their mouth is located ventrally ($A$ is correct).$2$. They possess $5$ to $7$ pairs of gills,which are separate and without an operculum ($D$ is also a characteristic,but ventral mouth is a primary diagnostic feature often cited in $NCERT$).$3$. Their skin is tough,containing minute placoid scales.$4$. Teeth are modified placoid scales which are backwardly directed.$5$. Their jaws are very powerful.$6$. They lack an air bladder,hence they must swim constantly to avoid sinking.$7$. The caudal fin is heterocercal (not homocercal).Note: Both $A$ and $D$ are characteristics of $Chondrichthyes$. However,in standard biology examinations,the ventral mouth is the most frequently cited primary characteristic.
