Bright orange shark spotted for the ‘first time ever' after being reeled in by fisherman in catch of a lifetime
A GIANT first-of-its-kind shark has been reeled in off the coast of Costa Rica.
The exceedingly rare shark, measuring in at over six feet long, exhibited a rare pigmentation condition causing it to appear orange.

The shark was thought to have xanthism, a rare pigmentation condition, affecting the fur, scales or skin of animals.
It creates yellow or golden colours in the animal but has never been observed in cartilaginous fish, a group that includes sharks, rays, and skates, in the Caribbean before.
The rare catch appeared to also show traits of albinism, with the shark boasting a pair of striking white eyes.
The nurse shark usually has brown skin which helps them blend into the seabed.

Based on the size of the shark researchers from the Federal University of Rio Grande concluded the unusual colour did not affect the shark's survival.
Animals with albinism or xanthism are much more visible which scientists believe lowers their survival rate in the wild.
The bright colouring caused by the pigmentation conditions makes affected animals easy targets for predators.
Both conditions can also increase sensitivity to sunlight and make it difficult for animals to find mates.

This makes the discovery of a shark that survived to adulthood with both conditions all the more significant.
It is unclear whether the unusual colouring offered any advantages to the shark or if it simply managed to thrive despite being more visible.

The striking fish was reeled in by some pals on a sport fishing trip in the Caribbean.
Its discovery prompted questions for marine biologists about genetic diversity in Caribbean nurse shark populations.
Scientists are now asking whether this is a one-time occurrence, or if it could signal a new genetic trend in the local population.

It has been recorded in only a few species of fish, reptiles, and birds, but there have only been a handful of confirmed cases.
In freshwater fish such as guppies, cichlids, and even goldfish, the condition sometimes produces striking yellow morphs.

Certain birds, like parrots and canaries, have also displayed golden plumage linked to xanthism.
Occasional reports in reptiles describe unusually yellow snakes or lizards.

Why scientists believe an ALIEN spacecraft could be hurtling towards Earth
Read on for six key theories about a mystery object tearing towards Earth proposed by Harvard experts SPACE ODDITY Why scientists believe an ALIEN spacecraft could be hurtling towards Earth A MYSTERY object tearing towards Earth at break-neck speed has raised fears that ALIENS are on their way here. Boffins warn that the odd entity, which astronomers are calling 31/Atlas, could be an ET craft set to launch probes on our planet. 4 The object astronomers are calling 31/Atlas could be an ET craft set to launch probes on our planet Credit: Getty 4 The discovery has raised fears that aliens are on their way here Credit: Getty Advertisement Estimated at more than 12 miles wide, it is whizzing through our solar system on a trajectory that will bring it within about 170million miles of us on December 19. A trio of scientists from Harvard University in America, led by astrophysicist Avi Loeb, have published a paper speculating whether it could be 'hostile' extraterrestrial technology. Nick Pope, a retired Ministry of Defence UFO investigator, said: 'It is not beyond the realms of science fiction that 31/Atlas could be an alien spaceship of some kind. 'Unusual behaviour' 'It's an unusual size, unusual acceleration, unusual course and unusual behaviour — those things combined very closely match a sort of mapping or survey mission. Advertisement READ MORE ON ALIENS STARRY EYED Nasa observatory could finally find ALIENS as it hunts for habitable worlds 'Of course, this could turn out to be just a comet or an asteroid — albeit an interstellar one, so interesting and incredibly rare. 'The good thing is this is a testable hypothesis. 'The clock is ticking down. We will know soon enough whether we're dealing with first contact . . . or just a big rock.' 4 Astrophysicist Avi Loeb speculated whether the object could be 'hostile' extraterrestrial technology Credit: Getty Advertisement 4 Retired Ministry of Defence UFO investigator Nick Pope Credit: Coleman-Rayner for The US Sun Here, Nick sets out the six key theories proposed by Harvard experts. 1. It's too large to be an asteroid. We do know asteroids in our solar system range in size but this is much bigger than average 2. Its rate of acceleration seems unusual for a natural object. The European Space Agency and Hubble space telescope calculate it is travelling at about 130,000mph. Nasa says at that speed, it is the fastest solar system visitor. Nasa's futuristic observatory could finally find aliens as it hunts for hidden habitable worlds, say experts 3. We spotted it very late. This was because it was coming in from the centre of the galaxy, where there are a lot of obstacles, light and stars. If you wanted to covertly send a probe into our solar system, this is exactly the course you would choose. Advertisement 4. Its course makes it very hard to intercept. At critical points where it might do something technological, such as perform a non-natural manoeuvre, it is blocked by the sun. 5. Passing close to Venus, Mars and Jupiter. This is like a mapping or survey mission. There is a very low probability of that happening naturally — the report suggests close to 0.005 per cent. That is statistically minute. 6. We won't see it. At its closest approach, the sun will be between the Earth and Atlas so we won't be able to see it. Again, this is exactly the course you would choose, as it can do all its sneaky braking manoeuvres and changes of course without us seeing it. It might do one of two things if this is technological. Advertisement It could change course and come to Earth itself. Or it could, if it's a mothership, deploy some probes that would come to Earth.

Sydney Chandler describes experience on the Alien: Earth TV series as 'a joy'
Sydney Chandler has described her first experience of leading a cast in the new sci-fi drama Alien: Earth as a "joy". The 29-year-old American actress plays Wendy, a humanoid robot with human consciousness, in Emmy-winning producer Noah Hawley's new series based on the acclaimed franchise. The Alien franchise began with Ridley Scott's 1979 film starring Sigourney Weaver as warrant officer Ellen Ripley, who takes on an extra-terrestrial lifeform called the Xenomorph. The new eight-episode series sees Wendy and a group of tactical soldiers make a discovery that puts them face-to-face with the planet's greatest threat. Chandler, who starred in Olivia Wilde's psychological thriller Don't Worry Darling and Danny Boyle's miniseries Pistol, about the Sex Pistols, said she was lucky to have such a supportive cast for her first lead role. "I felt like every day I was showing up to an incredible acting class," Chandler told the PA news agency. "I'm new to this game, and so it was just a joy to be able to work with such a supportive and such a giving cast who were there to play." Speaking of her character, she said: "There's so many layers to her and she's just a juicy character to jump into. "I did as much prep as you can for a character, there's no research you could do. "I really found my character once I started working off everybody." Alien: Earth is set in the year 2120, when the Earth is governed by five corporations: Prodigy, Weyland-Yutani, Lynch, Dynamic and Threshold. In this corporate era, cyborgs and synthetics, which are humanoid robots with artificial intelligence, exist alongside humans, but the world is changed when the founder of the Prodigy corporation unlocks a technological advance: hybrids (humanoid robots infused with human consciousness). Wendy, the first hybrid prototype, marks a new advance in the race for immortality and after Weyland-Yutani's spaceship collides into Prodigy City, Wendy and the other hybrids encounter new and terrifying life forms. The cast includes Deadwood actor Timothy Olyphant as Kirsh, Black Mirror star Alex Lawther as Hermit, Mary And George's Samuel Blenkin as Boy Kavalier, Guerrilla actor Babou Ceesay as Morrow and Bottom star Adrian Edmondson as Atom Eins. Blenkin said the filming experience was made a lot easier due to Hawley's practical approach to special effects. "We were lucky on this show because we're not doing much acting with tennis balls or anything like that that you do in a show where there's a lot of CGI," the 29-year-old actor explained. "Noah was really intent upon everything being practical. "There's no acting required when Cameron, the vegan New Zealander, is wearing a Xenomorph suit and is leering over you and drooling, and it's animatronic and it's real. "It was just a joy. We turn into kids on those sets." Hawley, who is best known for creating the Fargo TV series, said the "imperfections of reality are scarier than the sort of bloodlessness of computer-generated images". "All I'm trying to do is create the same feelings that you had when you watched Ridley's film or James Cameron's film," the 57-year-old writer and director explained. "Some of that we're able to achieve in new ways, but some of it is literally going back to the original cinema of optical illusions." Alien: Earth will launch on Disney+ on 13 August.
