I was bitten by a centipede no more than 3 inches long a couple of days ago. Very painful and within an hour my foot was numb. It did recover an hour or so later. God knows what this extinct (thankfully) would do.

I was about to post the same thing (albeit from the Guardian) - certainly a few for the Caption Competition there!! :D

CSIRO biodiversity and sea-floor mapping mission finds weird, wonderful fish species

https://www.abc.net.au/news/2022-10-29/ ... /101571160

rom fish that resemble dumplings to those that stand on their own "stilts" — deep in waters off Australia's coast, scientists are dredging up mysterious creatures.

Over 2,500 kilometres from Perth lie the Cocos (Keeling) Islands, one of Australia's most remote communities, part of the Indian Ocean Territories, which also encompass Christmas Island.

It is here that scientists are completing world-first biodiversity and sea-floor mapping, aboard the CSIRO's RV Investigator.

Life for species that live in waters about 5 kilometres deep is tough — there is little light and scarce food, and staying hidden is favourable.

It is for this reason, Museums Victoria's senior collections manager Dianne Bray, who is on board the ship, said the fish scientists manage to find in these waters are so terrifying and unique.

"They have to make bioluminescence to make lights to attract food, to hide, or camouflage themselves in the deep sea," she said.

"They often have big sensory organs, they often have big mouths with scary teeth in them to make the most of every meal they can."

It's researchers like that expedition who will eventually find MH 370.

I am not sure where this should be posted.

The Australain Kelpie is an amazing dog. There has been a recent TV program in Australia that follows 5 or 6 pups from birth through their training up to 1 year old. These dogs will attempt to round up chickens from when they are barely 1 month old.

The other amazing animal in this photo are the Jersey cows. They are one of the most docile and friendly cows ever bred. The look on their faces in this photo is almost human! Without too much effort the expression on their faces tells you exactly what they must be thinking, right from WTF!, to just ignoring the dog.

WA crayfish are about to turn in unison and head for deeper waters on 'whites run'

https://www.abc.net.au/news/2022-11-19/ ... /101668544

Millions of crayfish are set to descend into deep waters off WA's coast this week, in a "unique" migratory march.

The annual "whites run" is a natural phenomenon in which juvenile western rock lobsters from Bunbury to Kalbarri moult their red shells, becoming pale and soft.

They then turn to exactly 283 degrees north-west, and move from shallow coastal reefs to deep water.

Department of Primary Industries and Regional Development (DPIRD) scientist Simon de Lestang said the annual run was a bizarre event.

"It's a really unique thing to this species," Dr de Lestang said.

Choreographed crays like 'homing pigeons'

Each year between November and February, more than 10 million crays journey to waters between Geraldton and Shark Bay, where they settle on reefs.

Dr de Lestang said the crayfish use the Earth's magnetism to spin in the same direction for the migration.

"They all walk out at pretty much the exact same angle, 283 degrees, using magnetic reckoning, until they hit the deeper waters around about 100 to 200 metres," he said.

"And once they get into that loop and current, they turn and walk into the current and they walk northwards."

Dr de Lestang said lobsters tapped into magnetic forces in much the same way as homing pigeons.

"They can sense the magnetic fields underwater, and they can use that to know which direction they are going," he said.

Predicting the march

Dr de Lestang estimated this year's run would start around November 26 near Kalbarri, and lobsters in other areas would follow soon after.

But the prediction is not an exact science.

"That's been a question that a lot of people have sort-of answers to, like, it's got something to do with the Christmas trees flowering … or the seed coating the seagrass …or the moonphase," Dr de Lestang said.

The most scientific theory is water temperature, with warm waters prompting moulting and migration.

And if you were hoping to snap a photo of the march, you're out of luck — the crays prefer murky water.

"If it's dead calm, then they sort of wait for it to get a bit murkier," Dr de Lestang said.

Peak season for fishers

According to DPRID, cray stocks are high this year and record numbers of fishers are out to catch them, with 60,000 current licence holders.

Geraldton mayor and keen cray fisher Shane Van Styn said there were already plenty of mature red lobsters around ahead of the whites run, in what he called "the red run".

"The big ones move around to hide back in those holes and push out the smaller ones," he said

"But the whites run is truly the magic part of the year for catching crays.

"That's when the boat ramps fill up and cause all sorts of merry havoc down on the ramp."

Amazing Starling Murmuration in Somerset Captured on Camera

"A starling murmuration above a nature reserve has been captured on camera.

The mass swooping of thousands of birds happened above the RSPB's Ham Wall on Monday.

During a murmuration the starlings all fly and change direction in unison creating a dazzling display in the sky."

I guess I was non-appreciative, but very lucky when I was growing up. I used to live in Whitleigh, Plymouth, and we used to see a similar display over Tamerton Creek every evening.

Jonathan the world's oldest tortoise is celebrating his birthday with a big weekend of events

https://www.abc.net.au/news/2022-12-03/ ... /101730704

He was born not long after Napoleon died, and is now officially the planet's oldest known living land animal.

At 190 years old — more or less — Jonathan the Seychelles giant tortoise is celebrating his birthday on St Helena in the remote South Atlantic, where the defeated French emperor died in exile in 1821.

Based on shell measurements, it is believed Jonathan was hatched about 1832, and he was brought to the UK overseas territory from the Seychelles 50 years later.

He lives out a comfortable retirement in Plantation House, the official residence of the St Helena governor, where his birthday is being marked with events all weekend including the issue of a special stamp.

The celebration will peak on Sunday with a "birthday cake" made out of Jonathan's favourite foods.

He is particularly partial to carrots, lettuce, cucumber, apples and pears, according to his handlers.

Despite his advanced years, he is also partial to a young female tortoise called Emma, who is in her 50s.

"He still enjoys the ladies and I have heard him quite regularly in the paddock with Emma and he grunts," former governor Lisa Phillips said.

"I have to keep an eye on him when he is doing that — it was not in the job description when I became governor."

At the start of this year, Jonathan was given the Guinness World Records title as the world's oldest living land animal, and this month was also named as the oldest tortoise on record.

"When you think, if he was hatched in 1832 — the Georgian era — my goodness, the changes in the world," said Joe Hollins, a retired veterinarian who is Jonathan's main carer.

"The world wars, the rise and fall of the British Empire, the many governors, kings and queens that have passed, it's quite extraordinary.

"And he's just been here, enjoying himself."

While they hope for many more years, St Helena authorities have already made plans for the venerable chelonian's eventual demise: his shell will be preserved for posterity.
