When scientists first stumbled upon the elusive fish, the fish were known to scientists as an “old-timer,” because it had been caught and studied for over 2,000 years.
The oldest documented fossil fish, a 13-inch (31 cm) fish from the early Cretaceous period, lived more than a million years ago.
But until recently, little was known about how fish had evolved to become the fishes we know today.
The researchers behind the new study, led by Yale University’s Paul H. Riedel, believe that fish evolved as an escape mechanism from the stresses of modern fishing.
The fish evolved to be able to survive by swimming in the water.
“We are very interested in fish’s escape mechanism,” Riedal told Science News.
“Fish have to do something, and they have to survive.”
Fish are not unique to the ocean.
For thousands of years, fish have been known to have adapted to life in freshwater habitats such as lakes and ponds.
In recent decades, biologists have found a range of other marine species that have evolved to swim in water.
In the fish world, it is fish that are at the forefront of this evolution.
“When you think of the fish you are most familiar with, you would think of sharks,” said Riedol.
“And sharks are really large, they have big teeth and they are able to bite.”
But fish can also swim and dive and dive, which is why scientists are fascinated by the fish that live in water and also the fish species that are unique to marine environments.
For example, scientists have identified some species that can swim in the deep water.
Scientists have even found species that move to the surface and use their long tails to navigate.
Scientists say that fish have adapted well to these extreme environments because they are the only animals that can survive in these conditions.
But scientists are not sure how long the evolution of fish evolved.
Ruledel and his colleagues believe that the evolution was a very short time, and that it was the evolution that is more difficult to explain.
“I think the key thing is that there are many fish species with a very long, thin tail that they can use for diving,” Ruledal said.
The scientists also believe that there were no fish that have long tails that they used to escape from predators, or swim to the top of a lake to swim away.
The long tail may have served a function in the evolution.
For instance, the researchers found evidence that some fish use the tail as a means of moving quickly up a riverbed to escape predators.
In fact, scientists believe that these animals have been able to live on land for hundreds of millions of years.
Scientists think that these adaptations may have allowed fish to survive in the harsh environment of the ocean, and may have enabled fish to evolve to survive during the time of global warming.
“In order for fish to swim to a place that is warmer and safer than it was, fish evolved some very adaptive adaptations that allow them to live and thrive,” Ruling said.
“The key is, fish are not the only ones that can change the environment to their advantage.”
Ruledeld said that the next step in their research is to study how fish adapted to the harsh conditions of the deep ocean.
He said that he thinks the researchers will find that fish were able to adapt by creating “bioluminescent” algae that are able turn light into energy.
“This could be an important way of telling us about how fishes evolved and adapted,” he said.
