Video: an octopus rides a shark, an unusual marine encounter 🐙

An unexpected marine phenomenon was observed in New Zealand waters: an octopus riding a shark. This unusual scene, captured by researchers, raises questions about interactions between marine species.

During an expedition in December 2023, a team from the University of Auckland filmed an orange octopus clinging to a shortfin mako shark. This shark species, known for its speed, usually swims near the surface, unlike the octopus which lives mostly on the ocean floor.


The researchers, led by Rochelle Constantine, were surprised by this association. The mako shark, capable of reaching impressive speeds, seemed indifferent to its passenger. The octopus, on the other hand, firmly maintained its position on the shark's head.

The shortfin mako shark is an endangered species, primarily due to fishing for its fins. This observation highlights the importance of marine conservation to preserve these unique moments.

Interactions between marine species remain largely unknown. This discovery opens new perspectives on behaviors and relationships within the marine ecosystem.


The conservation of marine species is crucial to maintaining biodiversity. Protection initiatives can help preserve species like the mako shark and uncover other unexpected marine phenomena.

Why does an octopus ride a shark?

Interactions between marine species are often driven by survival needs or opportunities. In this case, the octopus might be seeking a means of transportation or protection from predators.

Mako sharks, with their speed and agility, provide an ideal mobile platform. By clinging to the shark, the octopus can move quickly through the ocean without effort.

This interaction could also be the result of a chance encounter. The oceans are vast, and encounters between different species are rare but possible.

Finally, this observation underscores the importance of marine research to understand the complex behaviors of underwater species.

What is the impact of fishing on mako sharks?

Shortfin mako sharks are heavily impacted by fishing, particularly for their highly prized fins. This practice threatens their survival.

Bycatch in tuna and swordfish fisheries is another major threat. Mako sharks are often caught unintentionally.

Their slow reproduction rate does not compensate for the losses due to fishing. This leads to a rapid decline in their population.
