The sail fin on an iguana is dorsal, meaning it is located on the back of the animal. This fin is formed by elongated spines covered with skin and helps in thermoregulation and communication among iguanas. It is particularly prominent in species like the green iguana.
The opposite of it's dorsal. The Dorsal is the back, Ventral is the Front. Hence the dorsal fin on ocean-based organisms
Dorsal is the back. Just think of a dolphin's dorsal fin and you'll never get ventral and dorsal mixed up again.
a fish with a high, sail-like dorsal fin
Caudal fin, Dorsal fin, Pectoral fin, Ventral fin, and the fin.
The 'dorsal-fin' extends upward from the back of organisms; so anything Ventral must reside near to an organism's front-side.
the ventral side. the dorsal side is the back of the rat ( think of the dorsal fin on a wale is on its back )
dorsal, in anatomy at least, means towards the back side of the body. the reason why fish have a dorsal fin is because its on their back, like a shark fin.
a dorsal fin is the one (or more) located on the back of a fish or aquatic mammal - its the fin that you see when a shark is swimming just under the surface of the water. Ventral fins are the ones toward the rear of the body and help in steering the animal through the water
The dorsal aspect of an organism's anatomy refers to the back side, while the ventral aspect refers to the front side. The key differences between the two are their locations on the body and the structures that are typically found on each side. The dorsal side often has features like the spine and dorsal fin, while the ventral side may have structures like the belly and ventral fins.
The "DORSAL" fin is the fin fish have on the top of their back. It is often shaped a bit like a triangle or sail.
The fin on the back of an orca is called the dorsal fin.
It's the ventral fin and My best Guess to it's purpose is that it helps stablize the forward movement in the fish, bit like the skegs on kayaks. possibly gives some direction control, like a rudder, and streamlining as well
