When a tourist boat sailed out of the harbor in the spring of 2024, the passengers probably don’t expect to witness an unusual scene: Tiburons of two types that usually do not share habitats They gathered around a decking corporate and fed peacefully for a day.
Loose Sharks did not show aggressive behavior with each otherNeither against the tour operators nor against the photographers who have observed the event. This type of observation can help scientists better understand inter -species relationships and social interactions between some of the greatest hunters in the oceans.
A lot of Sharks, especially those in the open sea, are hunters instead of scavengers. Nevertheless, a small part of his diet comes from the AAS, a behavior that they can perform when the chance occurs.
A bit common neighborhood
A team of researchers from the University of Hawaii has documented how two types of sharks that are rarely seen together, Huge oceanic sharks and tiger came together to devour the remains of a dead copy Next to these islands in the United States.
The meeting of these two types of ten kilometers from the coast of Isla Grande (Hawaii) was seen in April 2024 by a tourist ship. The occupants were able to observe the nutritional event for 8.5 hours, in which at least nine Shark Oceanic White Tip and Five Shark tiger. The finding appears Described in the magazine Frontiers in Fish ScienceAnd will scientists better understand the ecology of these shades, of which it is still very unknown.

«As far as we know, this is the First study that documents a meeting of tiger sharks and oceanic sharks that at the same time feed and peacefullyFrom a corpse, ”says one of the authors, Molly Scott, a marine biologist in Hawaii in Manoa. These species are rarely seen together in nature because of the various habitats they occupy.
Loose Oceanic white tiburons are an endangered species that reaches on average two meters long. They are lonely, very migrating and spend most of the time wandering by the oceans, so their studies are complicated.
In the spring and summer, however, they were grouped in Isla Grande (Hawaii). The Tiger sharks, a slightly larger and coastal species That grows on average three to four meters, inhabits throughout the year through the surroundings of that island.
But until April 2024 they were not seen together: «Although A maximum of 12 sharks that are fed at a very small and highly degraded corpse at intervalsWe do not observe aggression between species or within them. It seems that all individuals knew their place in the social hierarchy, “says Scott in a university explanation.
Order and hierarchy between sharks
Loose Tiger sharks, probably because of the larger size, were the dominant species. Loose Shark Smaller remained under the surface and fed with remains that drove. According to the researchers, they can be attracted to the remains that have been left behind by the greatest tiger sharks. The study was conducted in a relatively short period, because the body could not be found again the next day.
Scott states that this for people this Study offers a new perspective on sharksbecause «there are more than twelve in the water at all times between two and three people Shark nutrition and none of the photographers reported aggressive or problematic interactions with the Sharks ». «I hope this offers a new perspective Shark They are not human devout predators that are said to be, “he concludes.
