What animals have dorsal fins?
Dorsal Fin Basics

Where are dorsal fins found?
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom.
Do fish have dorsal fins?
Dorsal fins are located on the back. A fish can have up to three dorsal fins. The dorsal fins serve to protect the fish against rolling, and assist it in sudden turns and stops.
What animal has the largest dorsal fin?
Male Orcas have the largest dorsal fin of any marine mammal. It can get up to 6 feet tall. On females it's a bit shorter and more curved. The dorsal fin acts like a keel, and each dorsal fin is unique for each Orca.
Do dolphins have a dorsal?
The placement of the dorsal fin is thought to stabilize the dolphin in the water like a keel on a boat. Dolphins have a streamlined body, which lacks many external features. The shape or curve of the dorsal fin may also enhance their hydrodynamics.
Do all dolphins have dorsal fins?
Every dolphin has its own characteristics, including signature whistles, flukes and dorsal fins. Like a human fingerprint, no two dorsal fins are the same. Each dorsal fin has its own unique shape, height, thickness, markings and notches.
Do catfish have dorsal fins?

Do whales have dorsal fins?
Whales generally have four fins: two pectoral fins (instead of arms), a caudal fin (also called the tail) and a dorsal fin. ... The humpback whale stands out for its long pectoral fins that can reach one third of its body length. It is believed to be the largest appendage in the animal kingdom.
What is the top of the fish called?
The top fins are called dorsal fins. If there are two dorsal fins, the one nearest the head is called the first dorsal fin and the one behind it is the second dorsal fin. The belly or lower part of the fish is the ventral region.
What fish has dorsal fin?
In the higher bony fishes, the anterior part of the dorsal, or the first dorsal if there are two, is supported by spines. The anal fin is generally short-based but some species have anal fins that are long or longer than the dorsal fins, such as the burbot (Lota lota).
Do sharks have a dorsal fin?
Most sharks are designed for efficient motion through the water. They have three types of median fins (dorsal, anal, and caudal) and two sets of paired fins (pelvic and pectoral).
What is the dorsal fin of a shark?
Dorsal Fins
This is frequently the fin that is seen sticking out of the water. The dorsal fins keep the shark :upright:, i.e. prevent the body from tipping or rolling over. If there is a second dorsal fin, it is much smaller and positioned further down the torso, in line with the pelvic fin.
Where are killer whale eyes?
To open its blowhole, a killer whale contracts the muscular flap. A killer whale's eyes are on each side of its head, just behind and above the corner of its mouth, and in front of its white eyespot.
Do blue whales have dorsal fins?
Fins: A small triangular-shaped dorsal fin is located on the blue whale's back. This fin measures only one foot in height. The shape and size of the dorsal fin can be very different for each whale. The whale's flippers are short and the tail is broad and triangular in shape.
Why do orcas have dorsal fins?
The Lowdown on Dorsal Fins
"(The dorsal fin) helps them slip through the water more efficiently. Similar to the ears of elephants or the tongues of dogs, dorsal, caudal and pectoral fins also help eliminate excess heat during intense activities such as hunting."
