What is the difference between a right whale and a sperm whale?
The Main Differences Between a Sperm Whale and Blue Whale Appearance: Sperm whales have a ‘blocky’ head, with an S-shaped blow hole. The blue whale is, on the other hand, long and slender, and has a much larger mouth.
What makes right whales different?
Right whales have large, white, bumpy growths on their heads, called callosities (from the word callus). The shape, size and position of callosities are unique on each whale’s head and so scientists can use these patterns to identify individuals. Right whales have a distinctive v-shaped blow (spout).
What is the main difference between the two groups of whales?
There are two types of whale; baleen and toothed. The key difference between them is the way they feed and what they have inside their mouth. Baleen whales have baleen plates, or sheets, which sieve prey from seawater. Toothed whales have teeth and they actively hunt fish, squid and other sea creatures.
What is the difference between a blue whale and a right whale?
How do right whales size up? North Atlantic right whales (Eubalaena glacialis) are big, but they’re not the biggest whales. That distinction goes to the blue whale (Balaenoptera musculus), the largest animal on Earth. The orca’s (Orcinus orca) size of up to 31 feet (9.4 meters) makes it the largest dolphin.

How can you tell the difference between whales?
- Southern right whales have no fins on their backs. They have patches of roughened skin that can look like “a pile of stones” on their heads.
- Humpback whales can be distinguished by their small dorsal fin and long pectoral flippers, and they show their tail flukes more often.
- Blue whales are the biggest.
What is special about a right whale?
Their characteristic feature is callosities, which are raised white patches of roughened skin on their heads. Each right whale has a unique pattern of callosities that help scientists’ identify each individual.

What do right whales do?
Right whales are baleen whales, feeding on copepods (tiny crustaceans) by straining huge volumes of ocean water through their baleen plates, which act like a sieve. By the early 1890s, commercial whalers had hunted North Atlantic right whales to the brink of extinction.
Why do right whales float?
An unusually large 40% of their body weight is blubber, which is of relatively low density. Consequently, unlike many other species of whale, dead right whales tend to float.
