Cuttlefish bone, also known as cuttlebone, is an interesting and versatile natural material that has been used for centuries for various purposes. While the name might suggest it is a “bone,” cuttlefish bone is actually a hard internal shell found in cuttlefish, a marine animal closely related to squids and octopuses. This lightweight, porous structure plays a vital role in the cuttlefish’s buoyancy, allowing it to control its movement in the water. However, once harvested, cuttlefish bone has found a multitude of uses in human society, ranging from pet care to artistic applications.
In this article, we will explore everything you need to know about cuttlefish bone, including its uses, benefits, and significance in different fields. Whether you’re a bird owner, an artisan, or simply curious about marine life, this article will give you a comprehensive overview of the value and versatility of cuttlefish bone.

Cuttlefish bone, due to its unique structure and composition, has found a niche in several industries, including pet care, arts, and traditional medicine. It is highly sought after, particularly in bird care, where it is a rich source of calcium and other minerals that promote good health in birds.
What Is Cuttlefish Bone?
Cuttlefish bone is the internal shell of cuttlefish, an animal belonging to the cephalopod class, which includes creatures like octopuses and squids. Unlike these other marine animals, cuttlefish possess this hard, buoyancy-controlling internal shell. Structurally, the cuttlefish bone is highly porous, composed mainly of aragonite (a form of calcium carbonate), and has air-filled chambers that allow cuttlefish to float and maneuver effortlessly through water.
The bone itself, once the cuttlefish has died, is often washed up on beaches or harvested by fishermen. Its lightweight, chalky structure makes it easy to collect and use. It is an incredibly versatile material, especially for bird owners and artisans, and has even been used historically as a natural remedy in certain cultures.
Common Uses of Cuttlefish Bone
1. Bird Care and Nutrition
One of the most common uses of cuttlefish bone is as a calcium supplement for pet birds, particularly for species like parakeets, canaries, finches, and cockatiels. In fact, many bird owners are familiar with seeing cuttlefish bones hanging in bird cages. Birds naturally seek out calcium to support strong beaks and healthy bones, and cuttlefish bone provides an excellent, digestible source of this essential mineral.
Birds often peck at the cuttlefish bone, grinding it down with their beaks. Not only does this help maintain beak health by keeping their beaks trimmed and sharp, but it also provides a great source of nutrients like calcium, magnesium, and trace elements that are vital for their overall health. Birds that lack sufficient calcium in their diet may experience weak bones, brittle eggshells, and other health issues, making cuttlefish bone a valuable addition to their diet.
2. Art and Jewelry Making
Cuttlefish bone has a long history of being used in the arts, particularly in jewelry making and metal casting. Its soft, porous structure makes it an ideal material for carving and molding, allowing artists to create intricate designs. One of the most popular techniques involving cuttlefish bone is cuttlefish casting, a method where molten metal (like silver or gold) is poured into a carved mold made from cuttlefish bone.
Because the bone is easy to carve yet durable enough to withstand high temperatures, it’s perfect for creating detailed, one-of-a-kind jewelry pieces. Additionally, the natural grain of the bone adds texture to the metal, giving the final product a unique, natural finish. Many jewelers and artisans appreciate cuttlefish bone for its eco-friendly properties, as it is a natural, biodegradable material.
3. Calcium Supplements for Reptiles and Small Animals
Cuttlefish bone isn’t just for birds—it’s also a useful calcium supplement for other pets, such as reptiles (like turtles, tortoises, and lizards) and small mammals (such as guinea pigs and rabbits). Calcium is essential for bone growth, shell health, and the prevention of metabolic bone disease in reptiles.
Tortoises and turtles, for instance, require calcium to maintain healthy shells, and cuttlefish bone provides a natural, digestible source of this vital mineral. In reptile habitats, pieces of cuttlefish bone are often placed for them to gnaw on as needed. Similarly, small mammals like guinea pigs can benefit from the occasional calcium boost provided by cuttlefish bone, especially if their diet lacks enough calcium from other sources.
4. Aquarium Care
For aquarium enthusiasts, cuttlefish bone can be beneficial in maintaining water quality in tanks. It is often used to regulate pH levels and provide calcium to aquatic species, especially in saltwater aquariums or freshwater tanks with invertebrates, such as snails or shrimp. The slow release of calcium helps in stabilizing the water’s pH and hardness, ensuring a healthy environment for aquatic life.
5. Traditional Medicine and Human Use
In some cultures, cuttlefish bone has been used in traditional medicine for its purported healing properties. It has been ground into powder and used as an antacid or to promote healthy teeth and bones, owing to its high calcium content. While this use is less common in modern medicine, it’s a fascinating part of cuttlefish bone’s historical significance.
Additionally, powdered cuttlefish bone has been used as a natural tooth cleaner and in homemade toothpaste in the past. While its use for humans has diminished over time, its applications in alternative and traditional remedies are still remembered in some regions.
Environmental Significance of Cuttlefish Bone
Because cuttlefish bone is a natural, biodegradable material, it poses no environmental threat when discarded. In fact, washed-up cuttlefish bones are commonly found on beaches and are naturally broken down by the elements over time. This makes them a sustainable and eco-friendly option, especially when compared to synthetic calcium supplements or plastic alternatives used in crafting.
As a marine byproduct, cuttlefish bone is harvested in a way that doesn’t harm the environment or contribute to pollution. Many pet stores and artisan shops sell cuttlefish bone as a renewable resource, supporting eco-conscious consumption. The environmentally friendly nature of this product has also made it popular among those looking for green alternatives in their pets’ care and personal projects.
How to Use Cuttlefish Bone for Your Pet
If you’re a bird owner or have a reptile that can benefit from cuttlefish bone, here are some tips for proper use:
- For Birds: Simply attach the cuttlefish bone to the side of the bird’s cage using a clip or string. Birds will instinctively peck at it to meet their calcium needs and maintain beak health.
- For Reptiles: Place a small piece of cuttlefish bone in the reptile’s enclosure. Tortoises, turtles, and other reptiles will naturally chew on the bone to get their calcium intake.
- Replacement: Cuttlefish bones wear down over time, so be sure to replace them once they’ve been significantly pecked or gnawed down.
Conclusion
Cuttlefish bone is a remarkable natural resource with diverse applications that extend beyond its biological function in the sea. From providing essential calcium to birds and reptiles, to serving as a versatile material for artists and jewelers, cuttlefish bone remains highly valuable in both practical and creative fields.
Its role in bird care, particularly as a vital calcium supplement, highlights its importance in maintaining the health and well-being of pet birds. Meanwhile, its continued use in traditional crafts like cuttlefish casting demonstrates its enduring appeal to artisans worldwide.
Whether you’re a pet owner, artist, or simply curious about marine biology, cuttlefish bone offers something of value. Its versatility, sustainability, and accessibility make it a timeless resource that continues to enrich a variety of practices.
