The Marine Science Institute's monthly column, Science and the SeaTM, is an informative and entertaining article that explains many interesting features of the marine environment and the creatures that live there.  Science and the SeaTM articles appear monthly in one of Texas' most widely read fishing magazines, Texas Saltwater Fishing, the Port Aransas South Jetty newspaper, the Flour Bluff News, and the Island Moon newspaper. Our article archive is available also on our website.

Imagine if gorging on Thanksgiving dinner and the week’s leftovers caused you to grow an extra arm instead of adding inches to your waistline. The idea sounds crazy—unless you’re a sea anemone. These reef-dwelling creatures look like colorful flowers, but they are actually animals related to coral and jellyfish. Like coral, sea anemones spend their entire lives attached to the sea floor and hardly move. That means they needed to evolve ways to survive when environmental conditions around them change, including shifts in the availability of food.

It’s not often that a fish’s genetic analysis tells us something about human history, but that’s exactly what a discovery at the bottom of the Baltic Sea has done. The well-preserved remains of a fish from a royal shipwreck provides insight into both Scandinavian politics and the Baltic Sea’s ecosystem five centuries ago.

Scientists have known for years that microorganisms exist throughout the ancient layers of sediment hundreds of feet below the ocean’s floor. But it wasn’t clear whether those microbes are dead, alive or dormant. Despite being millions of years old, it turns out they are not dead. They are just hungry.

Whether on land or in the sea, most young mammals learn how to hunt and forage from their parents, most often their mother. But researchers have recently discovered that dolphins learn from more than just mom. New evidence suggests that dolphins also pick up new hunting skills from their peers.

You’ve probably heard, “a turtle carries its home on its back”, but the shells of loggerhead sea turtles are home to more than just the marine reptile inside. Researchers recently learned that turtles carry on their shells a thriving, diverse community of microscopic critters that is twice as big and diverse as scientists previously realized.

Many people are familiar with the annual growth rings in tree trunks. Most fishes have similar features in their bodies; their bones have alternating bands of dark and translucent tissue that indicate the passage of time. But the skeleton of a shark is made of cartilage, not bone. It turns out that vertebrae of whale sharks have rings like those in fish bones and tree trunks. How long does it take for a new “ring” to grow in whale shark vertebrae? Thanks to the atomic bomb, scientists determined that it takes about one year.

Laguna Madre — Mother Lagoon — is one of the saltiest bodies of water on the planet. The narrow lagoon stretches a couple of hundred miles along the coasts of Texas and Mexico, between the mainland and a series of barrier islands.

By the late 1960s, many Americans were getting fed up with bad news about the environment. A book early in the decade warned about the dangers of pesticides. An oil spill on the coast of California killed thousands of birds and other creatures. A river in Ohio caught fire. And pictures snapped by an Apollo astronaut showed Earth as a fragile blue ball.

To inform Americans about the problems, Senator Gaylord Nelson of Wisconsin organized an “environmental sit-in.” It was held on April 22nd, 1970 — the first Earth Day. And an estimated 20 million people took part.

Anyone who has tried to hitch a ride on a moving train knows it’s all about getting a really good grip. This is exactly what remoras piggybacking on larger fish need to do. Now scientists understand a little better how they do it.

The last time you saw a film in 3D, you probably weren’t grabbing for a tasty meal that seemed to hover just in front of you. But that’s exactly what happened when scientists put 3D glasses on cuttlefish and showed them a movie—all in the name of science.
