*Top 15* Amazing Right Whale Facts
Right Whales are one of the most endangered whales on Earth. These gentle giants move slowly through the ocean and usually swim close to the surface.
They received their unusual name from early whalers, who considered them the “right whale” to hunt because they were slow swimmers, floated after being killed, and produced large amounts of valuable oil and baleen.

1) Right Whales are one of the Most Endangered Whales
Right Whales are some of the rarest large whales on Earth. The North Atlantic Right Whale is especially endangered. Scientists estimate that fewer than 400 individuals remain, making it one of the most threatened marine mammals.
The population declined drastically due to centuries of commercial whaling. Recovery is slow because these whales reproduce slowly and face modern threats such as ship collisions and fishing gear entanglement.
2) There are 3 Right Whale Species
There are 3 Right Whales species. They share similar body shapes, feeding behavior, and distinctive callosities.
- Southern Right Whale
- North Atlantic Right Whale
- North Pacific Right Whale
| North Atlantic Right Whale | North Pacific Right Whale | Southern Right Whale |
|---|---|---|
| Found along the east coast of North America | Found in the North Pacific Ocean | Found in the Southern Hemisphere |
| Critically endangered | Extremely rare and poorly studied | Seen near Argentina, South Africa, Australia, and New Zealand |
| One of the rarest whales in the world | Population estimated at a few hundred or fewer | Population has recovered better than northern species |

3) Right Whales got their Name because they were easy to Hunt
Right Whales got their name for a really sad reason. During the commercial whaling era in the early 1700s North American whalers considered them the “right whale” to hunt.
There were several reasons for this: Right Whales swam slowly, swam close to shore, and produced large amounts of oil. But perhaps the most tragic reason is because due to their high blubber, Right Whales floated after death – rather than sank to the ocean floor.
As a result, by the 11th century Right Whales were hunted almost to extinction.
4) Right Whales are Baleen Whales
Right Whales belong to the baleen whale group. Instead of teeth, they have baleen plates hanging from their upper jaws to filter food from seawater. Baleen is made from keratin, the same material found in human hair and fingernails.
They have up to 300 baleen plates that act like giant combs that trap tiny prey. Their baleen can reach 8 feet long, making it some of the longest baleen of any whale species.

5) Right Whales Can Grow Up to 55 Feet Long
Adult Right Whales typically grow 45-55 feet long and weigh up to 70 tons. Females are generally larger than males, which is common among baleen whales.
Their bodies are thick and rotund with no dorsal fin, which helps distinguish them from many other whales.
6) Right Whales Have Enormous Heads
A Right Whale’s head is massive. In fact, the head can make up almost one-third of the whale’s total body length.
Their enormous mouths allow them to take in huge amounts of plankton-filled water while feeding.

7) Right Whales Have Rough Patches Called Callosities
Right Whales have white rough patches on their heads called callosities. These patches are not injuries. They are natural areas of thickened skin.
Tiny crustaceans called whale lice live on these patches, making them appear white or yellowish. Each Right Whale has a unique callosity pattern, allowing scientists to identify individuals like fingerprints.
8) Right Whales are Slow Swimmers
Right Whales usually swim at about 5 mph. They typically travel at around 3-5 miles per hour, although they can move faster for short bursts. Their slow speed was one of the reasons they were heavily hunted in the past.

9) Right Whales are “Surface Skimmers”
Unlike other baleen whales that lunge or dive to feed, Right Whales often skim along the surface with their mouths wide open. Their long, curved lower jaws help funnel tons of water in so their baleen can filter out tiny crustaceans. This feeding method allows them to collect large numbers of microscopic animals.
10) Right Whales Eat Enormous Amounts of Tiny Prey
Right Whales mainly eat copepods, tiny shrimp-like crustaceans only a few millimeters long. To maintain their massive bodies, they must consume thousands of pounds of these organisms every day.
Dense swarms of copepods are essential for their survival. Changes in ocean temperature can shift where these prey gather, making feeding more difficult.
11) Right Whales Produce V-Shaped Blow Spouts
When Right Whales surface to breathe, they produce a distinctive V-shaped blow. This happens because they have two widely spaced blowholes on top of their heads.
The V-shaped blow can rise 15 feet into the air. Whale watchers often use this V-shaped spout to identify Right Whales at a distance.

12) Right Whale Calves Are Huge at Birth
Right Whale calves are already enormous when they are born. They measure about 13-16 feet long and weigh around one ton at birth.
Within minutes, the calf must swim to the surface to take its first breath.
Right Whale Calves Grow Very Quickly. They may gain up to 100 pounds per day during the first months of life.
13) Right Whales Communicate with Powerful Calls
Right Whales produce a variety of low-frequency vocalizations. These sounds travel long distances underwater. They help whales maintain contact with other whales, locate potential mates, and coordinate movements
One common sound is an ascending “whoop” call, which may help whales gather together.

14) Right Whales Can Live for 70 Years or More
Right Whales are long-lived animals. Scientists estimate their lifespan to be 70 years or more, though exact ages are difficult to determine.
Some whales may live even longer. Unfortunately, many whales today do not reach their full lifespan due to injuries from ships or entanglement in fishing gear.

15) Right Whales Gather in Social Groups
Although they often travel alone or in small groups, Right Whales sometimes gather in Surface Active Groups (SAGs).
These groups can include several whales rolling, rubbing, and swimming around each other at the surface. Scientists believe these gatherings may be related to mating behavior, play, or social interaction.

Final Thoughts
Right Whales are among the most recognizable and endangered whales on Earth. Their enormous heads, distinctive callosities, and slow movements make them unique among marine mammals.
After centuries of whaling pushed them close to extinction, modern conservation efforts aim to give these gentle giants a chance to recover.
