Difference between Sharks and Dogfishes from Skates and Rays
Sharks and dogfishes are a group of fishes that belong to the class Chondrichthyes. Skates and rays are also part of this class. However, there are some distinguishing characteristics that set sharks and dogfishes apart from skates and rays.
Distinctly Marked Pectoral Fins
One of the main differences between sharks and dogfishes from skates and rays is the distinct marking off of their pectoral fins from their cylindrical bodies. Sharks and dogfishes have paddle-like pectoral fins that are not fused to their bodies, which allow them to swim more efficiently. In contrast, skates and rays have flattened pectoral fins that are fused to their bodies.
Ventrally Placed Gill Slits
Sharks and dogfishes have gill slits that are ventrally placed, which means they are located on the underside of their bodies. This allows for more efficient breathing while swimming. Skates and rays, on the other hand, have gill slits that are located on the top of their bodies.
Considerably Widened Head and Trunk
Another difference between sharks and dogfishes from skates and rays is the considerably widened head and trunk. Sharks and dogfishes have a broad and flattened head that tapers towards the tail. This allows for greater maneuverability while swimming. Skates and rays have a flattened body that is wider towards the head and tapers towards the tail.
No Distinct Demarcation Between Body and Tail
Sharks and dogfishes also lack a distinct demarcation between their body and tail. Their tails are generally symmetrical and streamlined, allowing for efficient swimming. Skates and rays, on the other hand, have a distinct demarcation between their body and tail. Their tails are generally flattened and broad, which allows for efficient movement on the ocean floor.
In conclusion, sharks and dogfishes differ from skates and rays in several notable ways, including their distinctly marked pectoral fins, ventrally placed gill slits, considerably widened head and trunk, and lack of a distinct demarcation between body and tail.

Sharks and dogfishes differ from skates and rays by [NEET Kar. 2013]a)...
SHARKS have a pectoral fin behind the head on either side of its body. These are often elongated and are used to keep the shark from sinking to the bottom of the ocean, as well as for steering the fish. The shark's fins are rigid and elongated. They are supported by cartilaginous, non-segmented rods called ceratotrichia. This strength and rigidity helps the animal to move swiftly and with agility, particularly useful when in pursuit of prey that darts away. RAYS have flattened disk-like bodies with five gill exit openings and their mouth generally located on their underside. They have large pectoral fins, which they move like wings to travel in the water, and their tails are generally long and slender, with many species having one or more sharp, venomous spines that can be used to inflict painful wounds.
So the correct option is 'their pectoral fins distinctly marked off from cylindrical bodies.'.
