The giant tortoise, one of nature's vegetarians. Or is it?
This video shows the astonishing moment an Aldabra giant tortoise hunts and kills a noddy tern chick.
It's the first time this behaviour has ever been documented and changes what scientists thought they knew about the species.
A study of the slow-speed hunt has been published in the scientific journal Current Biology.
The research was led by Dr Justin Gerlach, director of studies at Peterhouse, Cambridge.
"Everybody knows, or everybody thought they knew, that tortoises are vegetarians," he says.
"Pretty much any herbivorous animal will eat a bit of meat that they come across. It's a bit of free protein. So why wouldn't they do so? But that's just feeding on a bit of carrion. It's not hunting. It's not killing prey. And so this is totally unexpected."
The tern chick fell from a nest in the trees above.
The bird's natural instinct is that the ground is dangerous, so it refuses to leave the top of a log.
But with no escape route, the tortoise is able to corner its prey - albeit very slowly.
Gerlach says the tortoise appears to be an experienced hunter.So it seems to be an aggressive action and it seems to be deliberate. There's nothing very casual about this. So that all adds up to a tortoise that's done this before," he says.
The footage was captured on Fregate Island, a luxury resort in Seychelles.
It was filmed by conservation manager Anna Zora.
She and two volunteers had been counting a particular population of seabirds that live on the island.
By chance, they stumbled across the hunt and Zora immediately knew something special was happening.
"I said, guys, 'look at this tortoise, it's doing something strange," she says.
"It is only when something is strange enough out of the normality that your eyes pick it up. And that's, I think, exactly what happened."
There are more than 3,000 Aldabra giant tortoises on Fregate Island, the second largest colony in the world.
It was the first time Zora and her volunteers had even witnessed such behaviour and they had to fight their instincts to intervene.
"I remember one of the guys saying to me, 'oh no! We need to save the chick' and I stopped him, I said, look, if you were in the Savannah with a lion running after a gazelle, would you go and save the gazelle?" Zora says.
"It's a little bit the same concept. Nature can be cruel."
Fregate Island is privately owned and used for ecotourism.
Therefore, work has been done to regenerate natural habitats.
Sea birds, like the noddy tern, have recolonized the area.
Gerlach thinks this may why this behaviour has now been seen.
"That was probably something that occurred much more commonly in the distant past, when they would have been many islands with tortoises and with seabirds, but over hundreds of years, humans wiped out both the sea birds and tortoises," he says.
"And it's only the restoration work that's been done on places like Fregate that has allowed the habitats to recover, allowed the populations to recover. And I suspect what we're seeing is something that used to occur in the past, but no human has seen for 200 years."
Gerlach plans to study the behaviour further.
He wants to send students to the island to monitor the tortoises to determine more about their hunting skills.
A flight carrying Afghan evacuees fleeing the Taliban takeover of their country touched down early Wednesday in Uganda where they will be given temporary refuge, government and diplomatic officials said.
"The Government of the Republic of Uganda this morning received Fifty One (51) evacuees from Afghanistan who arrived aboard a privately chartered flight at the Entebbe International Airport," the foreign ministry said in a statement.
It said it followed a request from the US government to temporarily host "at-risk" Afghan nationals and others who are in transit to the United States and other destinations worldwide.
The US embassy in Kampala thanked Uganda for its "generosity and hospitality toward these communities".
"The Government of Uganda and the Ugandan people have a long tradition of welcoming refugees and other communities in need," the embassy posted on Twitter.
Uganda hosts one of the largest refugee populations in the world -- nearly 1.5 million according to the United Nations, mainly from neighbouring South Sudan and the Democratic Republic of Congo.
Most live in large refugee settlements in the sparsely populated north of the country but around 81,000 urban refugees live in the capital Kampala.
Aid agencies have repeatedly said that the international response to support refugees in Uganda, a country of about 44 million people, has been underfunded.
Moroccan Foreign Minister Nasser Bourita says his country is "keen" to maintain "strong ties" with Libya after meeting with member of the Libyan Presidential Council Abdullah al-Lafi in Rabat.
During a joint press briefing , Mr. Bourita stated that Morocco will stand by Libya unconditionally, to help promote security and stability of the country.
"Our meeting focused on two main points: the first is the bilateral relations between the two countries and the very strong and deep ties that bind the two brotherly peoples. I conveyed to the Vice President of the Libyan Presidency Council (Abdullah al-Lafi) that His Majesty the King is keen to maintain these strong ties between the two people."
Abdullah al-Lafi , the visiting member of the Libyan Presidential Council replied saying,
"We have just confirmed with his excellency the Foreign Minister a meeting between the two Libyan and Moroccan consular commissions that will be held next week to settle all the problems of obtaining visas and to follow-up on the flights file. Surely this commission will play a positive role to alleviate the suffering for both, the Libyan and Moroccan people."
According to the moroccan minister, the issue of national reconciliation, remains an essential factor to overcome the past and foster unity among all parties, especially as elections draw near in Libya.
He stressed that Morocco, which has led an exemplary process in this field through the Equity and Reconciliation Commission, is willing to share its experience and guide Libya.
Tanzania's president on Wednesday said five people are dead, including three police officers, after a gun battle with an armed man near the French Embassy in Dar es Salaam.
It was not immediately clear whether the shootout in the heavily guarded diplomatic area was a terror attack.
Liberatus Sabas, Tanzania's head of police operations, said the gunman attacked two police officers, took their guns and then "began shooting sporadically towards the French Embassy."
"He then took cover at a structure next to the French Embassy where he continued shooting," Sabas said.
Inspector general of police Simon Sirro told reporters the armed man was a foreigner and police believe he was from Somalia.
Sirro also warned the attack could be linked to the jihadist insurgency in neighbouring Mozambique, where a growing number of African nations are jointly pursuing the fighters.
The confrontation occurred shortly after President Samia Suluhu Hassan addressed security officials in another part of the city, Tanzania's commercial hub.
The president later said three police officers, a member of the auxiliary police and the armed man were killed, and she ordered an investigation.
The U.S. Embassy in a security alert warned citizens to avoid the area.
The shootout occurred not far from the scene of the deadly bombing in 1998 at the U.S. Embassy.
