Marine Biologists Surprise Discovery of The Shape-Shifting Mimic Octopus in Mozambique!
A Shape-Shifting Wonder Discovered in Africa
In a remarkable testament to the hidden wonders of the ocean, researchers at the Marine Megafauna Foundation, in collaboration with the Vilanculos Coastal Wildlife Sanctuary, have made an extraordinary discovery off the coast of Mozambique – the elusive and fascinating mimic octopus.
For the first time, the mimic octopus (Thaumoctopus mimicus), a species previously unknown in African waters, has been photographed, marking a significant range expansion of approximately 4700 kilometers from the Red Sea.

The Astonishing Abilities of the Mimic Octopus
Unlike any other octopus, the mimic octopus is a master of disguise. It can transform its shape, color, and behavior to look like other marine animals such as lionfish, flatfish, sea snakes, and more. This incredible skill is not just a performance; it's a survival technique that helps the octopus to confuse predators and catch prey.
From Indonesia to Mozambique: An Unexpected Journey
Typically associated with the waters of Indonesia, the mimic octopus, first described in the 1980s, has captivated underwater photographers and marine biologists alike with its remarkable mimicry abilities. “These sightings represent a significant expansion in this species known range,” explains Andrea D. Marshall, lead author of the study and Co-founder of the Marine Megafauna Foundation. “Seeing one in Mozambique was startling; it was instantly recognizable, yet its presence here was completely unexpected.“

A Testament to the Ocean's Mysteries
The octopuses were sighted in shallow waters of the Vilanculos Coastal Wildlife Sanctuary, exhibiting their unique behavior of mimicking other marine species. Taryn Gilroy, manager of the Sanctuary, shares her excitement: “Witnessing the mimic octopus within our Sanctuary was incredible. Its previously undocumented presence off eastern Africa underscores the richness and diversity of our marine life.“
The discovery of the mimic octopus in new waters is a call to action. It serves as a reminder of the ocean's vast and unexplored mysteries, and the need for continued research and conservation. “Discovering such extraordinary creatures in new habitats reminds us of the vast unknowns in marine environments, particularly in Africa,” Marshall adds. “We hope this finding will inspire awe and a renewed commitment to ocean conservation.“
