List of 9 Longest Fishes in the World
Did you know each fish is unique and has different personalities? Here is a ranked list of the nine longest fish species in the world by their maximum recorded length, showcasing a mix of cartilaginous and bony fish.
| Rank | Fish Species | Scientific Name | Max Length (feet) | Max Length (meters) | Fun Fact about the 9 Longest Fishes in the World |
| 1 | Whale Shark | Rhincodon typus | 62 | 18.8 | They are the largest fish in the world, are filter feeders and have teeth so tiny they only eat small shrimp and plankton. |
| 2 | Basking Shark | Cetorhinus maximus | 40.3 | 12.27 | They get their name because they spend a lot of time "basking" or swimming slowly near the water's surface with their massive mouths open. |
| 3 | Giant Oarfish | Regalecus glesne | 36 | 11 | Its extreme rarity and ribbon-like body make it a probable source of historical "sea serpent" tales; some cultures call it the "doomsday fish." |
| 4 | Largetooth Sawfish | Pristis pristis | 29 | 8.8 | Although they look like sharks, they are a type of ray, and their babies are born with their saw flexible and sheathed to protect the mother. |
| 5 | Tiger Shark | Galeocerdo cuvier | 29 | 8.8 | They are known for eating nearly anything; their stomachs have been found to contain surprising objects like tires and license plates. |
| 6 | Longcomb Sawfish | Pristis zijsron | 28.5 | 8.7 | Its long, narrow "saw" or rostrum can measure up to 5 feet (1.5 m) and is used to stun and slash at schools of fish. |
| 7 | Greenland Shark | Somniosus microcephalus | 24.5 | 7.5 | It is the longest-lived known vertebrate (backboned animal), estimated to live up to 400 years and not reaching sexual maturity until around 150 years old. |
| 8 | Beluga Sturgeon | Huso huso | 24.6 | 7.5 | It is the largest freshwater fish in the world and has existed for over 250 million years, earning it the nickname "living fossil." |
| 9 | Pacific Sleeper Shark | Somniosus pacificus | 23.3 | 7.1 | Despite its name and slow appearance, it is a highly effective stealth predator that glides silently to ambush fast-moving prey like squid and salmon. |
