*Top 33* Amazing Whale Facts
There are over 1.5 million Whales in oceans around the world. They have been on earth for 55 million years. Yet only 1% of the human population has seen one!
There are several reasons for this. Whales live in deep oceans, they are shy, they try to avoid boats, and more. Yet humans have been fascinated by these majestic creatures for centuries.
The 91 Whale species include Humpbacks, Blue Whales, Gray Whales, Sperm Whales, and Belugas. They use blowholes on the top of their head to breathe and they sleep half awake.
Read on to learn more Amazing Whale Facts!
1) Whales are Mammals
Whales are Mammals, which means that they breathe air through lungs, give birth to live young, and nurse them with milk. Despite living in the ocean, Whales share these traits with land mammals. They are warm-blooded and have a layer of blubber for insulation instead of fur.
2) There are 91 Whale Species
There are 91 different species of Whales. They vary widely in size. Some, like the dwarf Sperm Whale, are only around 9 feet long. Others, like the Blue Whale, can grow up to 100 feet long and weigh up to 200 tons, making it the largest animal ever to have lived on Earth.
Some species are found in cold polar waters, while others live in warm tropical seas. Each Whale species has its own habitat, diet, and way of communicating.
3) Whales are Baleen or Toothed
About 35 million years ago, Whales split into two major groups that we still see today: Baleen Whales and Toothed Whales.
- Baleen Whales don’t have teeth. Instead, they use comb-like plates called baleen to filter tiny shrimp-like creatures called krill, along with small fish, from the water. They are the largest Whales and have two blowholes.
- Toothed Whales have one blowhole and use echolocation to hunt fish, squid, and octopus in dark waters.
| Baleen Whales | Toothed Whales |
|---|---|
| Blue Whale | Orca (Killer Whale) |
| Humpback Whale | Beluga Whale |
| Fin Whale | Sperm Whale |
| Gray Whale | Pilot Whale |
| Minke Whale | Dolphins |
| Right Whale | Porpoises |
| Bowhead Whale | Narwhal |
4) Baleen Whales are powerful Filter Feeders
Instead of teeth, Baleen Whales, such as humpbacks and bowheads have bristly baleen plates hanging from their upper jaws. They gulp huge mouthfuls of water, then push it back out through the baleen, which traps tiny fish and krill inside. This process, called filter feeding, lets them consume thousands of small prey in a single bite.
Growing down from the upper jaw, baleen is found in the mouths of 11 species of large whales. It is made of material similar to your hair and fingernails. Baleen – once known as whalebone – was one of the most valuable parts of the whale. Flexible and strong, it was used for corset stays and umbrella ribs. Baleen is made of keratin, the same material as human hair and fingernails.
5) Whales Evolved from Land Mammals
As hard as it is to imagine, whales were once land animals! Around 55 million years ago, Whales evolved from a small, hoofed creature called Indohyus that looked more like a tiny deer than a Whale. Fossils of Indohyus were discovered in what is now the eastern Balochistan Province of Pakistan.
Soon came Ambulocetus (“the walking Whale”), a 10-foot predator that could walk on land and swim like a crocodile, lurking in rivers and lunging at prey. By 40 million years ago, species like Dorudon had fully traded land legs for powerful tails and fins, taking the final step toward becoming the Whales we know today.
6) Whales Communicate with each other
All whales – baleen or toothed – communicate using vocalizations. Most species produce simple sounds such as clicks and moans.
However, several baleen species such as Humpback, Blue, Fin, Minke, and Bowheads sing complex, repetitive vocalizations. Humpback whales are famous for their long, complex songs that can last for hours during breeding season.
7) Whales Communicate over Long Distances
Amazingly, baleen whales are able to communicate hundreds of miles though the ocean!!! They do so by using powerful low-frequency sounds.
In contrast, toothed whales use high frequency clicks and whistles that do not ravel far but can be used for fast communication.
Blue Whales have the distinction of being the loudest animals on Earth. They can communicate up to 500 miles with sounds up to 188 decibels.
8) Whales Hear through their Jaws
Whales rely heavily on sound to navigate, hunt, and communicate in the dark ocean depths. Instead of using earholes like humans, Whales pick up sound vibrations through fatty tissue in their jaws.
These vibrations travel through the head and into the inner ear, giving Whales an incredible ability to hear clearly underwater.
9) Whales Breathe through Blowholes
Unlike humans, Whales cannot breathe through their mouths. Instead, they use blowholes on the tops of their heads to inhale and exhale. This adaptation allows them to breathe quickly at the surface before diving again.
10) Whales Spout when they Breathe
When a Whale exhales, its warm breath hits the cooler air, creating a misty spout that can rise 10-15 feet high.
Each species has a distinct spout shape and height, which helps researchers identify them from a distance. The spray contains droplets of mucus, oil, and a small amount of water.
11) Whales Sleep Half-Awake
Whales need sleep, but because they must surface to breathe, they can’t fully shut down like humans do. Instead, they let one half of their brain rest at a time, a process called unihemispheric slow-wave sleep.
This allows them to stay alert enough to breathe, watch for predators, and even keep swimming slowly while they snooze! Some Whales rest at the surface, while others hang vertically in the water.
12) Whales Can See Above and Below Water
Whale vision works both at the ocean’s surface and underwater. Their large pupils expand to let in as much light as possible, helping them see in dim conditions.
However, once they dive too deep (around 660 feet) it becomes completely dark, even for them. That’s when Whales rely on echolocation and sound to navigate and hunt in the deep sea.
13) Whales are Champion Divers
Some Whales can dive more than 6,600 feet deep and hold their breath for over an hour!
Their bodies are built for the extreme pressures of the deep sea: flexible ribs that fold instead of breaking, blubber for warmth, and blood that stores extra oxygen for long dives.
Sperm Whales are the diving champions! They can dive an amazing 10,000 feet or two miles in search for prey such as squid, sharks, and fish.
14) Whales Sometimes Scrape the Ocean Floor
When fish swim in shallow schools near the seabed, Whales – especially Grey Whales – roll sideways and scoop them up. This bottom-feeding method often leaves scars on their heads and jaws from scraping against rocks and sand.
15) Whales are Pregnant 9-23 Months
Depending on the species, Whales are pregnant for 9-23 months.
The Dwarf Sperm Whale has the distinction of having the shortest whale pregnancy – 9 months. And the Bowhead Whale has the longest – 23 months.
Interestingly, Blue Whales are the largest animal on earth, but they are only pregnant for 10-12 months.
16) Whales have One Calf at a Time
Most Whales give birth to a single calf. Twins are extremely rare. Even so, these calves are born huge! A newborn Blue Whale calf can weigh up to 3 tons and drink nearly 100 gallons of milk per day.
17) Whale Calves can Swim at Birth
Whale Calves are born in the water. They are usually born tail-first underwater, ready to swim immediately. Their first challenge is to quickly reach the surface to take a breath of air.
18) Whale Mothers Protect and Carry Their Calves
A mother Whale strokes her newborn calf with her flipper and stays close to shield it from dangers in the ocean. She guides her baby until it grows strong enough to survive on its own.
Although Whale mothers can’t pick up their calves, their large bodies create a current in the water. The baby Whale drifts along in this stream, staying close enough to nurse or even nap while being gently carried by its mother.

19) When Whales Die, They Sink to the Ocean Floor
When Whales die, their carcasses sink to the bottom of the ocean.
This set off a feeding frenzy for numerous species such as sleeper sharks, rattail fish, hagfish, amphipods, worms, and bacteria.
20) Blue Whales are the Largest Animals on Earth
Blue Whales are the largest animal ever to live on Earth! Incredibly, they are bithan the biggest dinosaur, longer than three buses, and as heavy as 40 adult elephants.
Amazingly, Blue Whale calves are the size of a full-grown elephant at birth! To maintain this weight, they drink around 50 gallons of milk every day.

21) Fin Whales are one of the Fastest Whales
Fin Whales are long, sleek, and built for speed. Thus the nickname “greyhounds of the sea.”
They cruise at 20 mph for long distances and can sprint up to 30 mph, making them one of the fastest Whales in the ocean.

22) Humpbacks Sing Complex Songs
Male Humpbacks sing long, complex songs during breeding season. Each population has its own unique tune that evolves over time, almost like a cultural tradition.
Their haunting melodies became famous worldwide in the 1970s when a recording of Humpback songs turned into a top-selling music album. (Below).

23) Sperm Whales have the Largest Brain on Earth
Sperm Whales have the largest brain in the world! With a weight of 18-20 pounds, they are 5-6 times larger than a human brain.
Their enormous heads – which make up 1/3 of their body length – house this massive organ. As a result, Sperm Whales have remarkable intelligence for hunting and communication.

24) Gray Whales carry Hitchhikers
Gray Whales are covered in barnacles and tiny crab-like creatures called whale lice. These hitchhikers cling to the whales’ skin and feed on scraps in the water.
Calves are born smooth and gray, but they soon pick up these traveling companions.
25) Killer Whales (Orcas) are the Largest Dolphins
Although they are commonly called “Killer Whales,” Orcas are actually the largest members of the dolphin family. Their sleek, black-and-white bodies are built for speed and power, making them some of the ocean’s most impressive hunters.
Orcas are among the largest predators in the ocean. They can grow up to 30 feet long and weigh as much as 5.5 tons, about the size of a school bus!

26) Belugas Molt their Skin
Each summer, Belugas shed their outer layer of skin in shallow estuaries. They rub against gravel and rocks in “Whale Spas” to scrape off dead skin, barnacles, and parasites.

27) 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.

28) Minke Whales are Hard to Spot
Minke Whales are famously tricky to see. They surface for just a quick breath and often vanish before you can get a good look. Whale watchers sometimes call them the “stinky minke,” because – like many Whales – their breath has a strong, fishy smell.

29) Bowhead Whales are Arctic Ice Breakers
Bowhead Whales live in the icy waters of the Arctic Ocean. Since they must breathe air, they use their massive heads to smash breathing holes through thick sea ice.
Scientists think Bowheads use the echoes of their calls to measure ice thickness and avoid areas that are too solid to break.

30) Cuvier’s Beaked Whales Dive deeper than any mammal
Cuvier’s Beaked Whales hold the title for the deepest dive of any mammal ever recorded. One was tracked plunging nearly 2 miles below the surface and staying underwater for over two hours while hunting squid and fish.
31) Dolphins are Whales!
It might surprise a lot of people, but Dolphins aren’t just “relatives” of Whales. They are Whales! All Dolphins (including the well-known Bottlenose) are Toothed Whales.
So while they may look smaller and more playful than the giant Baleen Whales, Dolphins share the same family tree.

32) Porpoises Eat Nonstop
Porpoises eat a whopping 500 (small) fish per hour! (Which is 10 a minute). Which is hard to believe considering how small they are. Their flat, spade-shaped teeth are well-suited for gripping slippery fish.
33) Narwhals are Whales with a Unicorn-Like Tusk
Narwhals are toothed whales that live in the Arctic. They are known for having a single tusk that looks like a unicorn.
They spend their entire lives in icy Arctic waters around Canada, Greenland, Norway, and Russia. They are rarely seen, which adds to their mystery and legend.
