Sea crab, true to its label, seen transporting a sea urchin on its shell for safety.
In the vast and mysterious depths of the ocean, a unique and intriguing relationship unfolds between two unlikely partners: the carrier crab and the red urchin, scientifically known as Astropyga radiata.
The carrier crab, with its two back legs adapted for grabbing debris or neighbours, has been observed to carry the red urchin as a form of protection. Contrary to popular belief, the crab does not clamp down on the urchin, but simply props it up as a shield. This behaviour is not only seen in the carrier crab species, but also in many others that will carry almost anything as a form of protection.
The red urchin, with its bright, eye-catching colours and distinctive orangey star-fish-shaped top marked with linear blue dots, is easily spotted by divers. Despite its appearance, the red urchin is one of the ocean's most bizarre creatures, with some species covered in spikes.
Harilaos Lessios, a researcher at the Smithsonian Tropical Research Institute, made an interesting observation of this symbiosis between the red urchin and the carrier crab at the Galápagos Islands. He found that the relationship between these two species is often mutually beneficial and is one of nature's most common symbiotic relationships.
But the red urchin isn't just a passive participant in this relationship. When confronted with a predator, the urchin can be wielded like a weapon by the carrier crab. The urchin's spines, which can move several meters per minute and can migrate in small distances, can inflict intense pain on whoever's skin they puncture, although they are not fatal.
The relationship between these two species is not one-sided either. The sea urchin genome reveals striking similarities to humans, and research suggests that sea urchin spines might help treat bone fractures. Additionally, cardinal fish frequently use sea urchins and other bottom-dwelling creatures as a makeshift habitat.
In conclusion, the symbiosis between carrier crabs and red urchins is a fascinating example of the complex and intricate relationships that exist in the ocean. This relationship, while seemingly unusual, plays a crucial role in the ecosystem and serves as a reminder of the beauty and complexity of nature.
