There’s room for all types in a newly described fossil that shows baby fish swimming together in a school, approximately 50 million years ago. According to the authors of a new study published Wednesday May 29 in the journal Proceedings of the Royal Society B , this ex-school may be the earliest known fossil evidence that prehistoric fish swam in unison, just as modern fish do today.
The fish in question all belonged to the extinct species Erismatopterus levatus , and were apparently entombed together in the midst of a routine swim that may have been cut short by an underwater avalanche of sand, the researchers wrote. All but two of the wee specimens were swimming in the same direction and in a close-knit formation. To prove that the fish were indeed swimming in a school and not just fossilized that way by coincidence, the researchers ran a series of simulations to reproduce the group’s likely movements.
The simulations showed that the fish were apparently not only swimming in unison, but also did so according to a timeless set of behavioral rules that still show up today. In other words, individual fish swam close together, but not so close that they crashed. According to the authors, this ancient slab of dead swimmers shows that fish and possibly other animals evolved coordinated group behaviors at least 50 million years ago.
This synchronized swimming seems to have successfully saved the fish from being devoured by a predator , even if it could not save them from becoming a museum exhibit. Live Science. Please deactivate your ad blocker in order to see our subscription offer.

Another agency, the state Department of Environmental Quality DEQ , closed all 21 beaches, starting with some in late June to protect the public from blue-green alga that can cause rashes, vomiting and diarrhea. And the beachside waters evidently are safe to use, though no one in official capacity has made that public pronouncement.
Spraggins said that the public simply must use common sense and avoid exposing themselves to the alga when fishing near-shore. State epidemiologist Dr. The algal bloom has been caused by an abundance of non-saline water dumped into the Gulf from the Bonnet Carre Spillway, which has been open since Feb. The spillway is dumping water from the swollen Mississippi River into Lake Pontchartrain and then into the Gulf of Mexico. The nonsaline water is also contaminated by fertilizer runoff from farming operation all along the national river.
A lot of restaurants get their seafood from other states, Fontaine said. Restaurants that specialize in seafood are reaching out beyond the Gulf Coast for their fish. The DEQ beach closure extends only so far into the water, roughly waist deep, said Robbie Wilbur, spokesman for the agency. The charter captains said that they do not fish that close to shore regardless.
The DEQ has advised the public not to consume seafood from the sound. Whether that position changes based on the Marine Resources findings was not clear as of Thursday. And whether the DMR position leads to the lifting of the beach closures remains to be seen.

By Joe Brennan , video soure, Jukin. Two lucky fishermen have captured the moment a bald eagle swoops down to catch a fish but finds that its catch is too big to fly with. After realising that it’s unable to fly, the bird of prey decides to swim to shore using a butterfly style stroke. When the eagle eventually makes it to dry land, it reveals the size of it’s catch and it becomes clear why it could not re-emerge from the water with it. The bald eagle is the proud national bird symbol of the United States, and was declared an endangered species in America in The bird of prey has since been removed from the federal Endangered Species List, but due to its size and importance American heritage it remains an impressive sight to many.

50-Million-Year-Old Fossil Shows School of Baby Fish in Their Final Moments
These ocean giants can weigh up to 50, pounds 22, kg. Beautifully patterned with white spots and stripes, the foot-long whale shark is the largest—and one of the most striking—fish in the sea. Recent investigations into other shark species have revealed astounding life-spans: The Greenland shark, for example, can live nearly years , longer than any other vertebrate on Earth.
a few scales dating to million years ago, during the Late Ordovician Period. Emma Bernard, a curator of fossil fish at the Museum, says, ‘Shark-like scales eat prey bigger than themselves, while also evolving the ability to swim faster.
Levels of blue-green algae may be high during summer in some local lakes and reservoirs. Avoid coming into direct contact with the algae or swallowing lake water. Keep a close eye on pets or small children, who may ingest water containing toxins produced by these algae. Exposure to blue-green algae during swimming, wading, and water-skiing can lead to rashes, skin, eye irritation, and effects such as nausea, stomach aches, and tingling in fingers and toes.
After you swim, wade or ski, be sure to shower with warm soapy water. Swimming and boating permitted. Children and those with compromised immune systems should not swim. Avoid contact with algae. Avoid swallowing water while swimming. Take a bath or shower with warm soapy water after coming in contact with lake water. Do not use lake water for cooking or bathing.
It’s Fish vs. Dams, and the Dams Are Winning

But what did they evolve from, are they ‘living fossils’, and how did they survive five mass extinctions? Sharks belong to a group of creatures known as cartilaginous fishes, because most of their skeleton is made from cartilage rather than bone.
The only part of their skeleton not made from this soft, flexible tissue is their teeth. The group includes the more famous animals such as whale sharks and great whites, but also all rays, skates and the little-known chimaeras also known as ratfish, rabbit fish or ghost sharks. While often referred to as living fossils, sharks have evolved many different guises over the hundreds of millions of years that they have been swimming the oceans. The earliest fossil evidence for sharks or their ancestors are a few scales dating to million years ago, during the Late Ordovician Period.
Emma Bernard, a curator of fossil fish at the Museum, says, ‘Shark-like scales from the Late Ordovician have been found, but no teeth.
Tuna’s 25,000-mile swim down marine highway
A cohort of city, state and federal agencies are putting up a new set of signs along the Gowanus Canal that state the obvious: Do not fish, crab or swim in the toxic waterway. At one point, it was nicknamed Lavender Lake for its Pepto-Bismol-like coloring. Gowanus activist Linda Marino said she recently saw a man fishing along the canal.
The tag broadcast Terry’s trans-Pacific wanderings – three crossings in 20 months, a distance of 25, miles. Why the fish did this is a mystery.
One of New York’s most unique fish, the bowfin is the sole living survivor of a group of fishes whose fossil representatives date back to when dinosaurs roamed the earth. The features of today’s bowfin differ very little from their fossil ancestors dating back 65 million years, so they offer a true glimpse into New York’s prehistoric past. Bowfin are widespread through the eastern United States. Their native range extends from the St. Lawrence and Ottawa Rivers and Lake Champlain west through the Great lakes and south down the Mississippi to the Gulf of Mexico, west to the Texas border, east through the state of Florida and up the Atlantic coast.
Lawrence River and Lake Champlain drainages and have been introduced into a few waters in the southeastern part of the state.
6 Ways to Swim in the Adult Dating Cesspool (and One Work Around)
These mermaids yeah, mermaids are incredibly romantic, intuitive, and empathetic—of course you’re crushing on one! BTW, they’re amazing in bed, too. If you’re trying to catch one in your net, don’t treat ’em like an Aquarius—you’ve got to understand them in all their Pisces selves.
Most fish will tell you they like their food cold, and their bait a little worm. Some people don’t like fish puns, but they are kraken me up! We’re swimming along nicely.
The bowfin, commonly called dogfish in the Midwest, is truly a one of a kind fish. It is scientifically known as Amia calva, which is derived from the Greek, Amia meaning fish and calva meaning smooth. The common name of dogfish comes from their impressive set of very sharp conical teeth; much like a tyrannosaurus rex. The bowfin could logically be called a Jurassic Park fish. They are the sole survivor of a group of fish dating back million years to the Jurassic Age when dinosaurs roamed the Earth.
They are factually a living fossil. Bowfins are native to North America, common in the Eastern U. They are found from the Mississippi River drainage east to the St. In the U. We are at the northern limit of its range.
