Video footage of an octopus using on the again of a shark has enraptured international audiences since it was launched by researchers on the College of Auckland earlier this week.
The New Zealand cohort of ocean specialists noticed the unlikely duo, a Maori octopus perched atop a shortfin mako shark, within the Hauraki Gulf in the course of the summer season of 2023.
The researchers have been looking out for a feeding frenzy once they noticed the pair casually using the waves in tandem and playfully coined them “sharktopus.”
In line with a latest weblog publish by Rochelle Constantine, a professor of organic sciences on the College of Auckland and one of many researchers who found the bizarre sight, the crew first noticed a giant dorsal fin, signaling a shark of their neighborhood. Upon nearer inspection, they observed an “orange patch on its head.”
At first, they assumed it was an harm or that the shark had ran into a buoy. To substantiate their suspicions, the crew launched a drone and dropped a GoPro digicam into the water. That’s once they found the pair.
“An octopus perched atop the shark’s head, clinging on with its tentacles,” Constantine wrote.

“This ‘sharktopus’ was a mysterious discover certainly,” she added. “Octopus are totally on the seabed, whereas shortfin mako sharks don’t favour the deep.”
The octopus opted for a speedy trip, she defined, because the shortfin mako is the quickest shark species, swimming as much as 50 km/h.
Constantine’s space of experience is the Hauraki Gulf — Tīkapa Moana, Te Moananui-ā-Toi — the place she research the behaviour of sharks in the course of the summer season months.
The gulf is inhabited and visited by many forms of sharks, together with bronze whalers, which are sometimes seen by divers and fishers in shallow waters, and, extra generally, clean hammerheads.
Massive open ocean species such because the dusky shark, the blue shark and the shortfin mako, “in any other case generally known as the octopus taxi shark,” she joked, are more and more current within the area.

Much less is thought about smaller sharks residing close to the seabed, comparable to lemon fish and native carpet sharks, however international shark populations are in steep decline, attributable to overfishing, local weather change and low reproductive charges.
Constantine says the “sharktopus” encounter is a “reminder of the wonders of the ocean.”
“Among the finest issues about being a marine scientist is that you just by no means know what you would possibly see subsequent within the sea. By supporting conservation initiatives, we may also help to make sure that such extraordinary moments maintain taking place,” she concluded.
