They Came From The Sea

 In Strange & Mysterious Beasts (aka: Mysterious & Strange Beasts) I dealt with stranded unidentified (and very dead) sea creatures as well as globsters.  Now you will have to buy the book to read what I wrote but 2016/2017 had a few sea discoveries and mysteries worth taking a quick look at.

If I have missed any please let me know.

Fanged creature found on Texas beach after Hurricane Harvey

A mysterious fanged sea creature that washed up on a beach in Texas following Hurricane Harvey has been identified.

Preeti Desai found the decaying fish on a beach in Texas City, and asked Twitter for help.

She posted several photos with the caption: "Okay, biology twitter, what the heck is this?"

Her request was passed to biologist and eel specialist Dr Kenneth Tighe, who believes it is a fangtooth snake-eel.

He said it may also be a garden or conger eel, because "all three of these species occur off Texas and have large fang-like teeth".

Okay, biology twitter, what the heck is this?? Found on a beach in Texas City, TX.

It is thought that Hurricane Harvey, which brought strong winds and flooding to Texas, could explain why the creature was washed up.

The fangtooth snake-eel, also known as a "tusky" eel, is usually found in waters between 30 and 90 metres deep in the western Atlantic ocean.


Ms Desai, who was at the beach assessing the damage from the hurricane, told the BBC: "It was completely unexpected, it's not something that you'd typically see on a beach. I thought it could be something from the deep sea that might have washed on to shore." 


"My main reaction was curiosity, to figure out what the heck it was," she added.

Ms Desai said she posted the images on Twitter because she knows a lot of scientists use it, and a friend soon responded and contacted Dr Tighe.

 "I follow a lot of scientists and researchers. There's such a great community of these folks that are very helpful, especially when it comes to answering questions about the world or identifying animals and plants," she said.

She said she left the eel on the beach "to let nature take its course".

Strange purple sea creatures found in deep ocean trenches

Scores of spectacular and rare under sea species have been found by expeditions this year to some of the deepest trenches in the Pacific Ocean.
They include strange purple orbs, "mud monsters" and a bizarre swimming sea cucumber reminiscent of a flying Mary Poppins.
Another voyage found around 500 new undersea methane vents off the US west coast.
This doubles the number of known seeps, bubbling up a powerful greenhouse gas.
The gas vents were found by an expedition mounted by Dr Robert Ballard, the man who first located the wreck of the Titanic.

In his ship, the Nautilus, the Ballard team found new vents which were discovered off Washington, Oregon and California.
Little is known about the amount of methane that is coming out from these vents and how much is entering the atmosphere. But researchers say the new discoveries may better inform global estimates of these emissions.
"Methane seeps were basically unknown 20 years ago," said Prof Jesse Ausubel, from the Rockefeller University, part of the Nautilus team.

"At first people thought they were incredibly rare and now, thanks to these expeditions, these seeps may be very widespread, so the (methane) budgets may have to be recalculated, that's why the exploration is important."
One of this year's key expeditions mounted by the US National Oceanographic and Atmospheric Administration (NOAA), was a 59 day exploration of the Marianas Trench, the world's deepest underwater canyons.
As well as discovering three new "black smoker" hydrothermal vents stretching up to 30 metres in height, the voyage also revealed some rarely seen, mysterious creatures.

"I think it's always surprising what we find," said Dr Nicole Raineault, director of science operations at the Ocean Exploration Trust, which organised the expedition.
"We've looked in the Mediterranean, the Gulf of Mexico, the Caribbean and now the eastern Pacific Ocean with these remotely operated vehicles to get images of the sea floor, and we are continually surprised with the variety of life that we find."
"It just underscores how little we know about the ocean and how much more there is to discover our there."


BBCs Newsbeat on 24th February, 2017 reported on a Globster.  We all like Globsters, don't we? http://www.bbc.co.uk/newsbeat/article/39076311/what-is-the-hairy-blob-or-globster-found-on-the-philippines-shore

What is the 'hairy blob' or globster found on the Philippines shore?
Globster

A six-metre-long "hairy" sea creature has washed up on the shore of Dinagat Island in the Philippines and people have been questioning what it is.
An unidentified creature like this is often known as a "globster" and they've been washing up for years.
While some people think it might be new species, experts aren't convinced.
Lucy Babey, head of science and conservation for the animal charity Orca, says it's definitely the carcass of a dead animal - probably a whale.
"It's definitely a very decomposed sea creature in the later stages of decomposition," she tells Newsbeat.
"The carcass is about six metres long, but that's obviously not the whole carcass - there's no tail so it would have been bigger than that.
"That would suggest that it was probably a whale."

'But it could be a manatee'

"They have numerous whale species in the Philippines such as the blue whale, fin whales and humpback whales as well as smaller whales such as minke whales.
"But they also have manatees out there, so it could be a manatee.
"Unfortunately with this animal it is far too decomposed to be able to get a confident identification on what animal it was."

Whales and manatees aren't hairy though

She explains that the "hair" you can see in the image is actually more likely to be muscle fibres, where the body has gone quite far along the decomposition process.
"Other creatures could have sped up the decomposition process, but it looks like a normally decomposing carcass," she says.

So what was it doing there?

Lucy says that only 10% of whales and dolphins that die out at sea actually end up on the shore.
"There's an awful lot that die and stay out at sea," she says.
"They can come to the shore for a variety of reasons, but in this case, because it's an animal that died quite a while ago, it could have washed up because of storm surges."
Recently an earthquake struck in the region.
"That could have caused pressure on the seabed, which could have got the animal up nearer to the surface and onto the shoreline," says Lucy.
"It could have shifted the carcass, it could have caused differences in the tides and the strengths of the waves which would have washed it up on the shore."

Risk to human health

"There is obviously a risk of contamination," says Lucy.
"Any decomposing animal will carry diseases, so now they will need to safely dispose of it.
"In this country [the UK] we would put them in a landfill site, but they may move the carcass far out to sea."

Things like this don't wash up in the UK

"The animals we have wash up are pretty fresh. We get lots of whales, dolphins and sharks," explains Lucy.

Did anyone miss the story about the Welsh jelly-fish swarm? BBC News Wales covered it

Jellyfish 'mega swarm' washes up on four beaches

Thousands of jellyfish have washed up on beaches in Pembrokeshire and Ceredigion in what a conservationist has described as a "mega swarm".
More than 300 barrel jellyfish washed up in New Quay, Ceredigion.
And in Pembrokeshire there have been sightings in Tenby, Saundersfoot and Newport.
Sarah Perry from Cardigan Bay Marine Wildlife Centre said: "This is definitely a mega swarm. I have never seen them this big before."
She said the creatures do wash up each year but added that this was "unusual because of the number on our shores and the size of them".

Ms Perry said she believed the recent warm weather had sparked the boom in jellyfish, which can grow up to 88cm (35in) in diameter.
Numbers have grown in recent years because of mild winters allowing plankton, their main food source, to thrive.
Holidaymaker Wilson Dyer, from Suffolk, said: "I've been holidaying here for 40 years and I've never seen this before.
"They're all the way up the Cardigan Bay coast. It's intriguing, it looks like they all keeled over at the same time."

Conservationist Ms Perry said the abundance of washed up jellyfish could attract feeding leatherback turtles which would be an "amazing sight".
She encouraged the public not to move or touch the jellyfish.
"While they're relatively harmless they can, if touched, leave you with a rash similar to what you may get after touching a stingy nettle," she said.

On the 14th July, 2016 there had been another mass wash-up http://www.bbc.co.uk/news/uk-england-cornwall-36793950
Matt Slater, from the Cornwall Wildlife Trust, said: "It's shocking the amount of jellyfish which are turning up.
"There are millions of jellyfish in our waters at this time of year. When I'm out surfing, I keep hitting them with my board."
He added moon jellies were rare in Cornish waters five years ago, but they now seem to be abundant at this time of year.
There could soon be sightings of leatherback turtles - the largest turtles in the world - as these feed on jellyfish, he said.
Christian McConville, from the Plymouth Marine Laboratory, said: "Jellyfish do not have a tremendous amount of control over movement.
"It's likely the prevailing wind drew them to the coast and the tide left them on the beach."
He said this is the first major stranding event that he has seen this year.

Thousands of jellyfish have been washed up on a Cornish beach just days after a sperm whale got stranded and died at the same place.
Marine specialists say the current onshore winds are bringing in large numbers of jellyfish from the Atlantic.
The jellyfish, known as moon jellies, which used to be rare in Cornish waters, do not have a painful sting.
On Sunday, a female sperm whale was discovered in the shallows on Perranporth beach.
