During a routine aerial survey for marine wildlife carried out last Thursday off the most south-western tip of Cornwall, researchers from the University of Exeter’s School of Biosciences, the Marine Conservation Society (MCS) and Cornwall Wildlife Trust counted 19 sunfish in two hours, while the same survey two weeks earlier did not record any.   The Giant Ocean Sunfish (Mola mola), which can grow up to 10-feet and weigh over 2.2-tons, feed mainly on jellyfish and their name refers to their habit of lying at the sea surface on their side as if sunbathing.

Park officials hope a tropical fish will devour the bright green duckweed that has once again covered much of the pond at Randol Mill Park. The pond, which is visible from Interstate 30, was stocked with 15 pounds of tilapia this spring. "Once they start feeding, you should begin to see the plants in small concentrated areas," said parks Superintendent Oscar Carmona. "They'll constantly feed on the plants and algae."

Several hundred feet beneath the ocean's surface and woven throughout tropical reefs, live coral is one of nature's brightest lights. Its branches create a vivid curtain for brilliantly hued fish, impressive architecture that is built at the snail's pace of less than an inch a year. In a color range most often associated with fiery red-orange through salmon and pink tones, the coral hue long has attracted those who revel in warm, robust surroundings in the home. Now, in addition to the colors of coral, images from the reef also can be found in fashion and home decor. Click here to read this story.   Aquariums are Model Ecosystems. Our natural world is composed of a variety of ecosystems. Examples include forests, oceans, wetlands, prairies, scrub, deserts and lakes. Each manifests a combination of factors that influence what grows there.An aquarium offers a good way to study those factors. It is a small-scale model for learning about the balance of nature in the big world. Animals need water, food, shelter and space. Fish -- animals with fins -- may have plenty of water, but the water quality is vital, including such things as clarity, dissolved oxygen, pH and amount of nutrients.
