Meet the Octopuses That Carry Coconut Shells for Protection
When people think of animals using tools, chimpanzees, crows or even dolphins usually come to mind. Octopuses rarely make that list, yet these remarkable marine creatures have repeatedly demonstrated astonishing intelligence. One of the most fascinating examples is the veined octopus , which has been observed collecting discarded coconut shells from the seabed and carrying them for future use as portable shelters. Rather than simply hiding under rocks, these octopuses plan ahead, transport heavy objects and assemble them into protective homes whenever danger approaches. Their behaviour has amazed marine biologists and challenged long-held assumptions about intelligence in animals without backbones.
Unlike many marine animals that rely on permanent shelters, this octopus often lives in open areas with limited places to hide. To overcome this challenge, it searches the seabed for empty coconut shell halves or large clam shells that can later be used as portable refuges.
This behaviour requires planning, effort and an understanding that the objects will be useful in the future.
Although carrying the shells slows them down and leaves them temporarily exposed to predators, they continue transporting them until reaching a suitable location.
When threatened, the octopus quickly assembles two shell halves into a protective enclosure, creating an instant shelter.
This is considered one of the clearest examples of tool use in an invertebrate.
Octopuses That Collect Coconut Shells as Homes
A Master of Underwater Problem-Solving
The veined octopus (Amphioctopus marginatus), found in the tropical waters of the Indo-Pacific, is renowned for its remarkable ability to solve problems.Unlike many marine animals that rely on permanent shelters, this octopus often lives in open areas with limited places to hide. To overcome this challenge, it searches the seabed for empty coconut shell halves or large clam shells that can later be used as portable refuges.

Carrying a Home Across the Seabed
Researchers first documented this extraordinary behaviour in Indonesia, where veined octopuses were filmed lifting coconut shell halves beneath their bodies and "walking" across the seabed on their arms.Although carrying the shells slows them down and leaves them temporarily exposed to predators, they continue transporting them until reaching a suitable location.

Why Coconut Shells Make Perfect Shelters
Coconut shells are lightweight, durable and naturally curved, making them ideal hiding places.Next Story
