The dorsal fin has different functions in different whale species. In some whales (e. g. right whales and narwhals), the dorsal fin has disappeared altogether. In other species (e. g. blue and sperm whales), this fin is so small that it no longer really serves any purpose. 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. All captive adult male orcas have collapsed dorsal fins, likely because they have no space in which to swim freely and are fed an unnatural diet of thawed dead fish. SeaWorld claims that this condition is common—however, in the wild, it rarely ever happens and is a sign of an injured or unhealthy orca. Cold water diatoms adhere to their skin and sometimes give their bellies a yellowish tinge, giving the blue whale its nickname of "sulfur bottom. " Blue whales are long and streamlined. Their dorsal fins are extremely small, and their pectoral flippers are long and thin. Humpback. Humpback whales are mid-sized baleen whales that frequent our area in the summer months. They get their name “Humpback” from a small hump on their back located just in front of their small dorsal fin. These whales have a black body with white flippers (pectoral 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.
Shamu died that year at SeaWorld of pyometra (a uterine infection) and septicemia (blood poisoning). She was just 9 years old.
The main purpose of the dorsal fin is to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin) for propulsion.
Instead of arms and legs, dolphins have fins. The dorsal fin helps the dolphin maintain stability. The pectoral fin is used for steering and movement. Each tail fin is called a fluke.

Like the flukes, the dorsal fin is made of dense, fibrous connective tissue, without bones or cartilage. Dorsal fin size and shapes vary between ecotypes.
SeaWorld claims that this condition is common and natural for all orcas. However, collapsed dorsal fins are caused by the unnatural environment of captivity and are rarely seen in the wild. Only 1 to 5 percent of male orcas in some populations (and none in others) have fully collapsed 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.
Blue whale are never known to be aggressive by nature but there are small percentage of chances to be aggressive but never attack but only show sign of annoyance and swim away. There's no such thing as flee or fight for them. Just flee. Blue whale evolved into a machine with few predators and eat plankton?
Whales belong to a group of sea-dwelling mammals called cetaceans, which also includes dolphins. Humans and other land-dwelling mammals need large pelvic bones to anchor their hind legs and walk around. The bones are therefore connected to the base of the spine and the tops of the leg bones.
Humpbacks migrate from Alaska to Hawaii during the fall. They spend their winters in these warmer waters, mating and giving birth before returning to their northern feeding grounds.
Part 1 Distinguishing Whales by Appearance Estimate the whale's size. Check for a dorsal fin on the whale's back. Look for colors and patterns on the whale's body. Check the size and color of the whale's tail. Look at the colors and features of the whale's flippers. View the whale's head structure.
