Right whales can grow up to more than 18 m (59 ft) long with a highest-recorded length of 19.8 m (65 ft). Right whales are very robust whales, weighing 100 short tons (91 t; 89 long tons) or more. The largest known right whales can attain 20.7 m (68 ft) in length and weigh up to 135,000 kg (298,000 lb).

How big is a right whale?
Adult right whales are generally between 45 and 52 feet in length and can weigh up to 70 tons. When feeding, these whales swim slowly and use baleen to eat schools of small, shrimp-like crustaceans, called zooplankton.
Is a Right Whale a sperm whale?
Right whales are quite distinctive as the skull can occupy from 1/4 to 1/3 of the total length, a similar proportion to the Sperm whale in fact though the two species could hardly be more different in their feeding methods and preferences. Right whales have no dorsal fin nor any pronounced dorsal ridge.
Are there any right whales left?
Populations of the Critically Endangered North Atlantic right whale are estimated to have fallen by 30 individuals since 2019, leaving only around 336 of the animals left in the world.
How big are North Atlantic right whales?
North Atlantic right whales can grow between 45 and 55 feet and weigh up to 70 tons. They have a long arching mouth that begins above the eye and rows of baleen plates hanging on each side of their upper jaw.
How many right whales are left 2021?
Researchers estimate there are 336 North Atlantic right whales left on the planet. A new estimate of the number of endangered North Atlantic right whales left on the planet puts the population at 336, the lowest in nearly 20 years.
How many right whales exist?
About the Species. The North Atlantic right whale is one of the world's most endangered large whale species; the latest preliminary estimate suggests there are fewer than 350 remaining.
What is being done to protect the right whale?
New technologies that aim to decrease right whale entanglement include ropeless fishing gear – the deployment of gear without fixed vertical buoy ropes in the water column – that could dramatically reduce or eliminate right whale entanglements, while allowing fishermen to continue their livelihoods.
What eats a right whale?
The right whales' two known predators are humans and orcas.
What would happen if the North Atlantic right whale went extinct?
Fisheries rely on the abundance of their crop, and when a link in the food chain disappears, the loss upsets the ecosystem's balance, disrupting population sizes and the presence of natural predators and prey. If they're gone, the Atlantic Ocean would lose one of its largest and rarest whales.
How long can right whales stay underwater?
Whales can hold their breath for a very long time, and this ranges species to species. The average whale can hold its breath for about 60 minutes. The Sperm whale can hold its breath longer than the average whale, for about 90 minutes.
How many blue whales are left 2021?
Blue whales are still an endangered species and there are thought to be no more than 25,000 living in the world today.
Do Right whales eat fish?
Food Preferences and Resources
In general, baleen whales feed low on the food chain, primarily eating zooplankton and small fishes, which they encounter in large swarms or schools. Right whales eat zooplankton (animal plankton).
How big are whales balls?
It turns out that one fin whale testicle weighs around 7-8 kilos and is the size of a basketball.
How many blue whales are left?
Before whaling there may have been as many as 250,000; today, it is one of the world's rarest species, with the population of blue whales numbering just 10,000-25,000. Most biologists consider it among the most endangered of the great whales.
