The oceans have always held fascination for mankind. More than merely seeing it as a rich source of food, people have been captivated by the mysterious depths, the crashing waves, the wind and the weather that make the seas nothing man can conquer. Those who sought to understand life on the salt water were the first scientists, making observations and drawing conclusions. The conclusions were often wrong, but that could be said of modern researchers today. Still, the idea that intelligent sea life exists is accepted by most who study the ocean.
People alive today say they have been rescued by dolphins, who nudged them to shallow water after they had fallen from their boat. Whales seem to communicate with each other by song; some recent studies say that new songs are constantly being composed by these massive creatures. Those who spent their lives on the high seas learned all they could, since that could spell the difference between life and death, or at least between a profitable journey and financial disaster.
There might not be personal malignancy, as in 'Moby Dick', but there are plenty of instances when dolphins learn to recognize friendly divers, for example. Some divers say that even barracudas respond to repeated offers of food. Seagulls quickly take up panhandling if people on the beach feed them; in fact, it sometimes doesn't seem quite safe to do so, the birds get so excited and come in such numbers.
Goldfish were once thought to have a memory span of about three seconds. A modern study, however, explodes this idea. Not only can goldfish - not saltwater fishes, it's true, but representative of the species - learn to feed themselves by operating a lever, they also can learn to work it only at meal times. Moreover, researchers found that the fish remembered the trick for three months or more.
Every visitor to an aquarium with regular shows knows that dolphins and Orcas can be trained. They eagerly perform to earn a reward, but they also seem to enjoy the performance itself and the attention of the audience. Seals are famous circus stars.
Animals often exhibit traits once thought to be exclusive to humans. In one case, dolphins who were adorned with painted designs spent hours admiring their decorations in a mirror. Many creatures form family or group bonds, recognize each other after long separations, and remember people or animals they once interacted with. Some scientists think animals may remember words, from several to several hundred.
Scientists are also studying instinct and there is much debate about whether a behavior is reasoned or merely instinctive. Migratory behavior is considered instinctive, but is there reason behind a Canadian Goose's use of the stars for navigation? Is maternal love merely a survival instinct or something more? Those who believe in pure evolution lean toward everything, even human behavior, being instinctive, while those who favor creation may take a broader view.
Octopus may camouflage themselves with shells. Whales may work together to capture prey or sing a new song, never recorded before. Creatures have been observed using inanimate objects as tools. Some denizens of the deep live together in symbiotic relationships that seem to require intent and choice. It could be true that animals under the sea are thinking all the time.
