35 Facts About Frilled Shark

Meet the Frilled Shark

The frilled shark is a fascinating creature that has intrigued scientists and ocean enthusiasts alike. Known for its prehistoric appearance and elusive nature, this deep-sea dweller holds many secrets. Let's dive into some intriguing facts about the frilled shark.

1. 01The frilled shark is often referred to as a "living fossil" due to its primitive features that have remained unchanged for millions of years.
2. 02It gets its name from the six pairs of frilly gill slits that resemble a ruffled collar.
3. 03This shark can grow up to 6.6 feet (2 meters) in length, although most are smaller.
4. 04Unlike most sharks, the frilled shark has a long, eel-like body that allows it to move gracefully through the water.
5. 05Its mouth is filled with 300 trident-shaped teeth arranged in 25 rows, perfect for snagging slippery prey.
6. 06The frilled shark's diet mainly consists of squid, fish, and other small marine animals.
7. 07It can swallow prey half its size thanks to its extremely flexible jaws.
8. 08This shark is known to inhabit depths ranging from 160 to 660 feet (50 to 200 meters), but it has been found as deep as 5,150 feet (1,570 meters).
9. 09The frilled shark's reproductive process is unique; it has a gestation period that can last up to 3.5 years, the longest of any vertebrate.
10. 10Females give birth to live young, usually between 2 to 15 pups at a time.
11. 11The frilled shark's slow reproductive rate makes it vulnerable to population decline.
12. 12It has a wide distribution, found in the Atlantic and Pacific Oceans, but sightings are rare due to its deep-sea habitat.
13. 13The frilled shark's scientific name is Chlamydoselachus anguineus.
14. 14Its first scientific description was published in 1884 by German ichthyologist Ludwig Döderlein.
15. 15The frilled shark's brain is relatively small compared to its body size.
16. 16It has a large liver filled with low-density oils, which helps it maintain buoyancy in deep waters.
17. 17The frilled shark's skin is covered in tiny, tooth-like structures called dermal denticles.
18. 18These denticles reduce drag and protect the shark from parasites and injuries.
19. 19The frilled shark's eyes lack a nictitating membrane, a protective eyelid found in many other sharks.
20. 20It relies on its keen sense of smell to locate prey in the dark depths of the ocean.
21. 21The frilled shark's movement is often described as serpentine, resembling that of an eel or snake.
22. 22It is believed to be a slow swimmer, conserving energy in the nutrient-scarce deep sea.
23. 23The frilled shark's coloration ranges from dark brown to gray, providing camouflage in its deep-sea environment.
24. 24It has been observed to perform a unique hunting strategy, coiling its body and lunging at prey like a snake.
25. 25The frilled shark's teeth are designed to trap prey, making it difficult for them to escape once caught.
26. 26It is considered a rare species, with few specimens ever captured or observed.
27. 27The frilled shark's elusive nature has made it a subject of many myths and legends among sailors.
28. 28Despite its fearsome appearance, the frilled shark poses no threat to humans.
29. 29The frilled shark's skeleton is made of cartilage, like other sharks, which is lighter and more flexible than bone.
30. 30It has a single dorsal fin located far back on its body, unlike most sharks that have two dorsal fins.
31. 31The frilled shark's pectoral fins are small and rounded, aiding in its eel-like movement.
32. 32It has a unique method of respiration, using its gill slits to pump water over its gills while remaining stationary.
33. 33The frilled shark's stomach can expand significantly, allowing it to consume large meals when food is available.
34. 34It is often caught as bycatch in deep-sea fisheries, posing a threat to its population.
35. 35Conservation efforts are challenging due to the frilled shark's deep-sea habitat and elusive nature.
