Swim hook up
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.
Whale sharks may live up to a century, Cold War bomb dating reveals
Like any other student, he made mistakes, contemplated new ideas, and tried to best manage his time. Fish does. During his senior year of high school in Waterloo, Canada, Fish started making daily video blogs vlogs and posting them on YouTube.
Sturgeon are anadromous fish, which means they spend most of their life it is a member of one of the oldest families of fishes, Acipenseridae, dating back Atlantic sturgeon swim out to sea, where they undertake extensive migra- tions of up.
All rights reserved. Carbon dating has validated that the species is the longest-lived freshwater fish known. Scientists just added a large, sucker-mouthed fish to the growing list of centenarian animals that will likely outlive you and me. A new study using bomb radiocarbon dating describes a bigmouth buffalo that lived to a whopping years, crushing the previous known maximum age for the species—26—by more than fourfold.
That makes the bigmouth buffalo, which is native to North America and capable of reaching nearly 80 pounds, the oldest age-validated freshwater bony fish —a group that comprises roughly 12, species. In recent years, thanks to more advanced aging techniques, scientists have discovered many species of fish live longer than originally thought—the Greenland shark, for instance, can live past years.
Before the study authors even aged a single fish, they had a hunch that these fish, which live mostly in the northern U. The team removed thin slices of otolith—small calcified structures that help fish balance while they swim—from wild-caught bigmouth buffalo, most of which were harvested by bowfishers. The researchers then used a microscope to count the growth rings on each slice of otolith. Their first counts yielded estimates of fish that live more than 80 and 90 years old.

To validate these extraordinary age estimates, Lackmann, a graduate student at North Dakota State University, and colleagues turned to bomb radiocarbon dating, a well-established method that compares the amount of the isotope carbon in animal tissue to concentrations of carbon released in the mids during atomic bomb testing.

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.

Alligators, oranges and Florida Man are among the many things the state is known for, but beautiful natural swimming spots are some of the best things the Sunshine State has to offer. Here are eight natural areas within two hours of campus that make for a perfect day trip. So put on your swimsuit, grab a sub and cover yourself with sunscreen before heading out into the water. Kelly Park is a acre public park in Apopka.
Its clear, swift creek and cool waters make for a beautiful day going with the flow of the natural spring, which pumps an average of 26, gallons per minute and is a cool 68 degrees year-round. In addition to the springs, the park features nearly seven miles of hiking trails, swimming hole, camping sites, picnic areas, volleyball courts, playground and the river head for the mile Rock Springs run that connects to Wekiva Springs State Park.
What to do: Rent a tube from a vendor outside the park before you arrive and relax as you float. The run takes about 30 minutes, but you can get out at many stops along the way. Aside from sea turtle sightings, the location offers soft, white sand and bright blue water, which many surfers use to practice for the annual Founders Day Surfing Competition each May.
Our advice: Bring a change of clothes and explore the nearby shops and restaurants that make up this beach community, which is the oldest in Brevard County. This west Orange City attraction is known as a popular manatee refuge, but the refreshing degree water is an awesome location for humans to take advantage of too. Feel free to bring along snorkeling, scuba diving and fishing gear to use in the spring.
Swim With The Fish
The world’s oldest fish hook has been unearthed at a site in East Timor, alongside evidence that modern humans were catching fish from the open ocean as far back as 42, years ago. The discoveries, from a limestone cave site known as the Jerimalai shelter on the north of the island, are published today in Science 1. A broken shell fishhook found in East Timor provides evidence that humans were engaging in off-shore fishing much earlier than thought scale is in millimetres.
Sue O’Connor, an archaeologist at the Australian National University in Canberra, and her colleagues found two broken fish hooks made from shells. They dated one to approximately 11, years old and the other to between 23, and 16, years old — the earliest known example of fish-hook manufacture. The oldest previously known fish hooks are associated with the beginnings of agriculture, which in South East Asia was around 5, years ago, says O’Connor.
Fish without swim bladders, like sharks, have to swim constantly to keep have been carved into Egyptian tomb walls dating back 4, years.
My last dating post was about how many people think of adult dating as dumpster diving. Sadly enough, most women agreed with me. Not surprisingly, one of these fellows was a yogi, into self-growth and seeing the good in others. I wrote about it here. The idea was fun and daring, the reality was dreary. I was still lonely. One guy turned out to be angry and damaged. I think the lines between dating someone and FWB can be blurred.
Plenty of Fish – Swim to your Soulmate
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.
herring have left the ocean to swim up the Hudson River to any one of scores But in a more recent era, the fish have been literally hitting a wall as many structures dating to the s and s in the East were built for.
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.

Candiru (Vandellia cirrhosa), also known as cañero, toothpick fish, or vampire fish, is a species however, despite ethnological reports dating back to the late 19th century, the first documented case of the removal of a candiru from a human urethra did “Can the candiru fish swim upstream into your urethra (revisited)?”.
Fish are aquatic animals that were among the first vertebrates animals with a backbone to evolve on Earth. They are divided into two broad groups: teleosts, which have a bony skeleton and symmetrical tail and include most familiar fish species, and elasmobranchs, which have a skeleton made of cartilage and include sharks, rays and skates. There are about 30, species in the two groups combined equal to the number of all other vertebrate species combined in existence today.
Bony fish are found around the world in both salt and fresh water, from the tropics to the Arctic and Antarctic, and from the coasts to the deepest parts of the ocean. They range in size from the pygmy goby, at one-third of an inch 9 millimeters , to the marlin, which can grow to nearly 12 feet 3. The behaviors and life cycle strategies of fish is almost as varied as the number of species.

In January, contributor Jon Hurdle reported on how a series of dams along the Brandywine that date back some years were being targeted for removal or modification. The goal is to allow shad and more to return to their ancestral spawning grounds again for the first time in two centuries. Listen Listening More than two centuries after settlers began to build dams across the creek to power their grain mills, the fish are making their way back into the creek where they were once so abundant that they were one of the most important food sources for early American communities.
In mid-April, an angler caught the first documented shad of the season in a stretch of the creek that is now open for migratory fish for the first time since the colonial era, thanks to the demolition last year of a dam at West Street, Wilmington. The dam, built in , and another a few yards downstream dating from , previously blocked the upstream passage of fish including American and Hickory shad, herring and alewives when they attempted to return to their ancestral spawning grounds in the Pennsylvania section of the creek some 25 miles away.
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 definition of candiru differs between authors. The word has been used to refer to only Vandellia cirrhosa , the entire genus Vandellia , the subfamily Vandelliinae , or even the two subfamilies Vandelliinae and Stegophilinae. These smaller species are known for an alleged tendency to invade and parasitise the human urethra ; however, despite ethnological reports dating back to the late 19th century,  the first documented case of the removal of a candiru from a human urethra did not occur until , and even that incident has remained a matter of controversy.
Candirus are small fish. Each has a rather small head and a belly that can appear distended, especially after a large blood meal. The body is translucent, making it quite difficult to spot in the turbid waters of its home.
