Baby sharks are being born small, exhausted and undernourished as a result of rising ocean temperatures caused by climate change, according to a new study.
Researchers looked at the effects of warming waters on juvenile epaulette sharks (Hemiscyllium ocellatum) — a small, egg-laying species of shark found in the Great Barrier Reef, that spends most of its time on the seafloor. Studying their egg sacs in a laboratory at the New England Aquarium in Boston, the researchers discovered that warmer waters led to premature births of the baby sharks inside.
"The hotter the conditions, the faster everything happened, which could be a problem for the sharks,” study lead author Carolyn Wheeler, a doctoral candidate at the University of Massachusetts.
f rising temperatures continue unabated, there may come a point when these sharks can no longer properly develop, warn the researchers.
That could devastate the whole Great Barrier Reef ecosystem.
"Sharks are important predators that keep ocean ecosystems healthy," Wheeler said in the statement. "Without predators, whole ecosystems can collapse, which is why we need to keep studying and protecting these creatures."

now do baby humans
BULLOBAMA !!
MSN style “Science”
They’ll adapt or be replaced, but nature will go on.
Speaking of ocean life...I remember at a family reunion at a NC beach, my liberal brother in law told me, “they were here first” when I complained about the jellyfish.
Later when we thought they were gone, he got in the water. A jellyfish was sitting on his shoulder when he came out. He screamed like a school girl and threw it in the sand and stomped on it. I said...”they were here first”. Hahahahahahahahahahahahahahahasnorthaha. It was soooo good!
How about the nonsense that shark migration today follows the route of the slave ships, as they wait for almost two centuries for more corpses to be dumped overboard?
Yes, “they” say that - the slave trade changed shark migration routes to this day...

Of course they are, because sharks have only survived 450 million years as a species, so naturally warmer water will kill them. They’re very delicate creatures.
I spend a month in the lower Keys in the summer and I grew up in south Florida.
There are more sharks in the water than there ever have been in my lifetime. I think it’s because they outlawed long line fishing in the (90s)?
Regardless, if they are born skinny, it isn’t hurting them.
And shark fins make such excellent soup, too. Such a shame!
Sharks are cannibalistic in the womb... so they never go hungry before birth.
Two forms of within-the-womb cannibalism are known in sharks. The most extreme form of intrauterine cannibalism — in which the largest and strongest embryo actually consumes its lesser womb-mates — is termed “embryophagy” or, more colorfully, “adelphophagy” — literally “eating one’s brother”. It was discovered accidentally in 1948, when a researcher probing the uteri of a late-term Sandtiger Shark (Carcharias taurus) was startled by a bite on the hand. To date, adelphophagy is known only in the Sandtiger.
The less extreme and by far more common form of intrauterine cannibalism — in which developing embryos feed on a steady supply of tiny, unfertilized eggs — is termed “oophagy” (sometimes called “oviphagy”) — meaning “egg-eating”. The earliest documented case of oophagy dates back to 1907, in the Porbeagle (Lamna nasus). Both forms of intrauterine cannibalism continue throughout embryonic and fetal development, so that at birth each pups often has aa conspicuously swollen abdomen known as a “yolk stomach”.
NOTE TO SELF: only swim in warm water!!!!
"Estimates of how many blacks were lost at sea in the roughly 400 years of the slave trade in the Americas vary wildly. Some, like Mr. Akeem, place the figure between 100 million and 200 million. Others say perhaps as many as 14 million people perished. Whichever is true, many historians note that the numbers of enslaved Africans who died at sea were so great that sharks learned to follow the slave routes because they fed on the bodies thrown overboard."

I know I have seen baby shark 50 times since our grand daughter bas born. It should be banned from Gitmo!
I thought it was bc of Trump
