Shark teeth have captivated humans across cultures and history. These mineralized remnants offer biological insight, cultural meaning, artistic inspiration, and spiritual significance. This article delves into shark tooth symbolism, mythology, trade, and more to explore these multifaceted icons.

The Biology of Shark Teeth

The Biology of Shark Teeth

Shark teeth provide a window into the evolution and form and function of one of the ocean’s apex predators. Their specialized structure equips sharks to seize and shred a variety of prey.

Tooth Structure

  • Made of tough enamel and bone-like dentine proteins, giving durability and strength.
  • Enamel protects outer surface while dentine adds compressive strength.
  • Sandpaper-like texture created by hard enamel and soft dentine layers rubbing together. Allows teeth to saw through tough skin, tendons, and bones.
  • Chemical properties vary. High mineral content in bones sharks eat helps teeth withstand forces.
  • Flexible cartilage jaws absorb shock and protect teeth from breaking while biting.

This adaptable structure makes shark teeth some of the hardest materials in the natural world.

Tooth Shape and Function

Shark species have evolved distinct tooth shapes aligned with preferred prey (see table from original article).

  • Pointed: Grip soft bodies of fish and squid. Common triangular shape with single, sharp cusp. Allows quick puncture. Seen in active predators like great whites.
  • Serrated: Sawing, slicing teeth. Up to 300 teeth engaged at once when biting. Allow sharks to carve chunks from large prey. Found in tiger sharks, bull sharks.
  • Blunt: Wide molar-like teeth crush hard shells of mollusks, urchins, crabs. Common in bottom-dwelling nurse sharks and wobbegongs.
  • Needle-like: Dense rows of tiny teeth filter small prey. Specialized for filter feeding sharks like whale and basking sharks.

This variety equips sharks to utilize many niches and food sources in the ocean.

Conveyor Belt Dentition

Sharks constantly shed old, damaged teeth and regrow new ones in “conveyor belt” fashion:

  • New generations of teeth develop in rows behind existing teeth, within gum tissue.
  • When old tooth is lost, the next tooth rotates forward to take its place.
  • Rate of tooth replacement varies by species. Some sharks replace teeth every one to two weeks.
  • Provides a continuous supply of fresh, functional teeth throughout a shark’s life.
  • Allows them to maintain the specialized teeth needed to capture and process prey even after damaging teeth during feeding.

This helps explain the abundance of shark teeth across geological history. Over a lifetime, a shark may shed thousands of teeth.

Cultural Significance

Cultural Significance

In addition to biological insights, shark teeth and shark imagery permeate human culture, mythology, and symbolism.


The shark’s role as an apex ocean predator translates into diverse mythological symbolism (see examples in original article).

  • Seen as monsters and sea demons in Greek myths like Scylla, personifying the perils of marine travel and seafaring.
  • Revered as powerful animal gods and guardians by Polynesians, with the ability to protect or destroy voyaging seafarers.
  • Thought to have supernatural powers, like the shark gods Kamohoalii and Makua in Hawaiian myths who could take human form.

Their menacing, sharp teeth feature prominently, conveying danger and primal awe.

Native American Culture

For North American tribes, shark teeth carried protective powers and cultural importance:

  • Seminoles: Warriors carried teeth into battle to channel the shark’s prowess. Teeth used in weapons and jewelry as talismans. Believed they imparted bravery, cunning, and speed in the water.
  • Cherokees: Tribal medicine men wore necklaces of fossilized shark teeth to gain foresight and intuition for healing. Thought teeth enhanced spiritual communication.
  • Coastal Tribes: Crafted ceremonial rattles from dried shark jaws decorated with rows of teeth. Used in rituals, dances, and naming ceremonies to call on shark energy.

This reverence reflects Native American respect for the shark’s strength and connection to water spirits.

Polynesian Culture

Across Polynesia, islanders incorporated shark teeth into cultural practices and warfare:

  • Warriors wore necklaces and pendants of teeth to invoke courage and prowess in battle. Believed teeth channeled shark guardian spirits.
  • Fishermen donned shark tooth jewelry and amulets to ensure safe voyaging and protect from shark attacks.
  • Offerings of food and teeth made prior to ocean fishing and harvesting. Thought to confer favor from shark gods.
  • Carved weapons and clubs embedded with shark teeth. The more teeth added, the more potent the weapon’s power.
  • Men and women wore teeth as beautiful adornments, symbols of status and social rank.

Teeth thus embodied Polynesian’s close but wary relationship with sharks.

Scrimshaw Art

On long whaling expeditions from the 17th to 19th centuries, sailors practiced scrimshaw, carving whale ivory:

  • Etched vivid scenes of whaling, women, and nature into whale bone and teeth. A maritime craft and leisure activity.
  • On rare occasions, fossil Megalodon shark teeth used. Carved with simple designs due to hardness.
  • Added intricate details using ink and pigments. Vibrant embellishment with reds, blues, greens, and blacks.
  • Gave scrimshawed teeth as souvenirs upon return to land or sold for income. Highly collectible today.

Though difficult, shark teeth provided sailors a canvas for their seafaring experiences.

Spiritual Significance

Spiritual Significance

Beyond culture, shark teeth have acquired esoteric and mystical associations.

New Age Beliefs

Some New Age followers ascribe healing properties and charm to shark teeth:

  • Seen as channels to access primal energy or empathy with oceanic realms.
  • Fossilized Megalodon teeth especially valued for ancient origins.
  • Worn as jewelry or displayed in homes to confer clarity, instinctual guidance, and luck in water ventures.
  • Used in rituals by spiritualists to deepen insight or as protective talismans.
  • No evidence of healing powers, but provides psychological benefits for some adherents.

However, commercialization risks exploiting threatened shark species.


  • In Christianity, sharks with gnashing teeth traditionally depicted evil forces or the peril of sin.
  • But also represent power of faith to overcome danger, like stories of prophet Jonah swallowed by a great fish.
  • In Buddhism, shark teeth motifs found in temple decoration symbolized perseverance in overcoming obstacles.
  • In Hinduism, some temples contain statues of sharks or the shark goddess Jara, symbolizing life’s cycles.

Teeth represent nature’s ferocity and humanity’s struggle to surmount it.

Commercial Trade

Beyond symbolism, shark teeth command monetary value in jewelry, decor, and tools.

Jewelry & Accessories

From pendants to earrings, shark teeth drive an artisanal jewelry market:

  • Wire wrapping or minimal drilling allows fossil teeth to be worn as pendants, beads, or earrings.
  • Fresh modern teeth of certain sharks also used, but raises conservation concerns.
  • Most prized are pristine Megalodon fossils, especially rare colors like purple, blue, and turquoise. Large, symmetrical teeth.
  • Retail for $25 to over $10,000 based on size, perfection, species, and uniqueness.
  • Also incorporated into accessories like wallets, bracelets, business card cases.

Jewelry allows owners to exhibit exotic shark teeth as adornments.

Home Decor and Curiosities

Teeth displayed around homes, offices, and events:

  • Framed in shadow boxes or mounted on stands as conversation pieces.

Threats to Shark Teeth

Threats to Shark Teeth

While shark teeth will likely persist as fossils, sharks face escalating threats worldwide:

  • Overfishing kills up to 100 million sharks annually for meat, fins, liver oil, and teeth.
  • Shark tooth trade alone kills up to 10 million a year. Hunters motivated by profits.
  • Depletes shark populations already endangered by habitat loss, bycatch fishing, and climate change.
  • Strict regulations on tooth collecting are needed to prevent disappearance of living sharks.

Sourcing teeth sustainably from regulated fisheries and avoiding modern teeth can help mitigate this impact. Supporting shark conservation allows us to continue learning from these ancient animals.


Whether as biological relics or objects imbued with human meaning, shark teeth have captivated us across cultures and eras. They reveal secrets of lost prehistoric seas and evolutionary pasts. They anchor mythology and lore that helped ancient peoples explain the natural world. They drive appreciation of sharks as icons of the ocean’s wonder and peril. If properly protected, these mineralized documents can continue to tell their timeless story for many generations to come.
