Types of Whales
Whale Species↕ | Max Length↕ | Population Estimate↕ | Diet↕ | Known For↕ |
|---|---|---|---|---|
Blue Whale | 30 meters (100 ft) | 10,000-25,000 | Krill (up to 4 tons/day) | The largest animal to ever live — bigger than any dinosaur, heart is the size of a golf cart, tongue weighs as much as an elephant, blood vessels large enough to swim through, a blue whale calf gains 90 kg per day from mother's milk, nearly hunted to extinction (reduced from 350,000 to 5,000), the most magnificent creature on Earth and we almost lost it forever |
Humpback Whale | 16 meters (52 ft) | 80,000+ | Krill, small fish (bubble-net feeding) | The singing whale — male humpback songs can last 20 hours and are heard 20 miles away, all males in a population sing the same song which evolves over the season, bubble-net feeding is a cooperative hunting strategy unique to humpbacks, spectacularly acrobatic breaches (40-ton full-body leaps), conservation success story (recovered from 10,000 to 80,000+), the whale that makes whale watching worthwhile |
Orca (Killer Whale) | 9 meters (30 ft) | 50,000+ | Fish, seals, whales, sharks (depends on ecotype) | The ocean's apex predator — technically the largest dolphin not a whale, different ecotypes specialize in different prey (some eat only salmon, others hunt great white sharks), orcas flip sharks upside down to induce tonic immobility and eat just the liver, matriarchal society led by grandmother orcas, captivity controversy (Blackfish documentary, SeaWorld), the animal with the most complex culture outside of humans |
Sperm Whale | 18 meters (60 ft) | 300,000+ | Giant squid, deep-sea fish | Moby Dick's species with the largest brain ever — dives to 2,250 meters to hunt giant squid in total darkness, the largest brain of any animal that ever lived (8 kg), echolocation clicks are the loudest sound made by any animal (230 dB, could theoretically vibrate a human to death), ambergris (whale vomit) is used in luxury perfumes, inspired Herman Melville's Moby Dick, the deep-diving champion of the mammal world |
Beluga Whale | 5.5 meters (18 ft) | 150,000+ | Fish, squid, crustaceans | The canary of the sea — the most vocal whale with a repertoire of clicks, whistles, and clangs audible through boat hulls, the flexible neck (unfused cervical vertebrae) allows head turning unlike other whales, the pure white color and permanent smile make it the most photogenic whale, melon (forehead) changes shape during vocalizations, beloved in aquariums (controversially), the friendly whale that approaches boats out of curiosity |
Narwhal | 5 meters (16 ft) + 3m tusk | 80,000+ | Arctic cod, halibut, shrimp | The unicorn of the sea — the tusk is actually a left canine tooth that spirals counterclockwise and can grow to 3 meters, the tusk is a sensory organ with 10 million nerve endings (detects temperature, salinity, and pressure), medieval Europeans believed narwhal tusks were unicorn horns (worth more than gold), lives in Arctic waters under sea ice, climate change threatens their ice-dependent lifestyle, the most mythical-looking real animal |
Gray Whale | 15 meters (49 ft) | 27,000 (Eastern Pacific) | Bottom-dwelling crustaceans (filter from sediment) | The longest migration of any mammal — 20,000 km round trip from Arctic feeding grounds to Mexican breeding lagoons, friendly whales in Baja California approach boats and allow petting (the 'friendly gray whale' experience), nearly extinct twice from whaling but recovered, the only baleen whale that feeds by scooping sediment from the ocean floor, the whale that taught humans that whales are gentle |
Bowhead Whale | 18 meters (60 ft) | 10,000+ | Zooplankton, copepods | The longest-lived mammal — can live over 200 years (stone harpoon points from the 1800s found in living whales), the thickest skull of any animal (can break through Arctic ice), the largest mouth of any animal, baleen plates up to 4 meters long, lives entirely in Arctic waters, Inuit communities sustainably hunt bowhead whales as cultural tradition, the whale that was alive when Napoleon was emperor |
Right Whale (North Atlantic) | 15 meters (49 ft) | ~350 (critically endangered) | Copepods (tiny crustaceans) | The most endangered large whale — named 'right whale' because whalers considered it the 'right' whale to hunt (slow, floats when dead, lots of oil), only ~350 North Atlantic right whales remain, ship strikes and fishing gear entanglement are the main threats, calving rates are declining, each death is individually mourned by the conservation community, the whale we might actually lose in our lifetime |
Minke Whale | 10 meters (33 ft) | 500,000+ | Krill, small fish | The common whale you've probably seen — the smallest and most abundant baleen whale, the whale most commonly seen on whale watching tours, still hunted by Japan, Norway, and Iceland (the controversial whaling nations), curious and approachable, the white band on the pectoral fins is the field ID mark, the whale that anti-whaling campaigns focus on because it's the most hunted, the most accessible whale encounter for tourists |
Fin Whale | 26 meters (85 ft) | 100,000+ | Krill, small schooling fish | The second-largest animal ever — nicknamed 'the greyhound of the sea' for speeds up to 37 km/h, asymmetric coloring (right lower jaw is white, left is dark) is unique in the animal kingdom, low-frequency calls travel hundreds of kilometers, was the primary target of 20th-century industrial whaling (700,000 killed), recovering slowly but still endangered, the whale that proves even the second-largest animal ever can be overlooked |
Pilot Whale (Long-finned) | 7 meters (23 ft) | 200,000+ | Squid primarily | The most social whale — travels in pods of 20-100 related individuals, mass strandings are disturbingly common (entire pods beach themselves, possibly following a sick leader), one of the most intelligent cetaceans with the most neocortical neurons of any mammal, the Faroe Islands' grindadráp hunt is controversial, the strong family bonds mean pod members won't abandon a stranded individual, the whale whose loyalty becomes its greatest vulnerability |
