A Weedy Seadragon looks just like it sounds.. A mini sea dragon that would blend in with corals and seaweed very well! To avoid mouthfulls of sand when feeding, this animal will feed on its side and suck up tiny mycids! Compared to the leafy sea dragon, weedies have less flamboyant projections and are usually reddish in color with yellow spots. Weedy sea dragons have very long, thin snouts, slender trunks covered in bony rings, and thin tails which, unlike their seahorse cousins, cannot be used for gripping.
Terns are a common seabird that frequently get mistaken for seagulls. These graceful birds are characterised by their silver-grey upperparts, white underparts, black cap and red bill, as well as long tails. Almost all terns migrate, and the Arctic tern migrates every year from the Arctic to the Antarctica –a 25,000 mile trip, one way! Common tern colonies usually number around 2,000 birds, but can be as large as 20,000. They are often shared with other tern species such as Arctic and roseate terns.
Giant clams were first documented by an Italian explorer, as early as 1521. The largest known specimen of the giant clam, till date, was found in 1817, off the north-western coast of Sumatra. It was 4.49 ft. long, and its shells weighed 510 lbs. In 1956, another giant clam that was about 3.77 ft. long was found in Japan, with its shells weighing about 730 lbs. Because of its sessile nature, the moment the giant clam chooses a spot as its ‘home’, it fastens itself to the same, and then cannot go elsewhere for the rest of its life.
It’s not a jellyfish! The Portuguese Man o’ War may look like a bloated jellyfish, but it’s actually a siphonophore—a bizarre group of animals that consist of colonies made up of dozens, hundreds, or even thousands of genetically-identical individual creatures.
Not much is known about the Spiny Devilfish, but what is known mostly revolves around it’s spines. It has poisonous spines on the dorsal, anal and ventral fins. This fish is predominantly well camouflaged (and so easy to miss) and lies buried up to the eyes and mouth, waiting for prey to swim by to ambush by lunging forward and inhaling their prey with their large mouths.
Probably the most remarkable fact about the Jewel Fish, however, is the relationship of the mated couple, which comes as close to a “married life” in the full sense of the word as can be found among fish.
Seals spend much of their life in water! Their thick fur and blubber offer protection against freezing temperatures. Seals have more blood in their body than other animals. Since blood cells keep the oxygen, seal can dive longer than other animals. Seal can hold its breath for 2 hours which is a record in the animal world. They can dive up to 1000-1300 feet deep when they are searching for food.
Algal blooms are one common source of thick sea foams. When large blooms of algae decay offshore, great amounts of decaying algal matter often wash ashore. Foam forms as this organic matter is churned up by the surf. Most sea foam is not harmful to humans and is often an indication of a productive ocean ecosystem. But when large harmful algal blooms decay near shore, there are potential for impacts to human health and the environment.
Swimming with dinosaurs! Longnose Gar (and other species of this family) are ancient fish perfected suited to thrive in conditions that would easily kill most fish. They can gulp air when necessary, allowing them to survive in low oxygen and higher salinity water than most fish.
In some instances, however, the negative ecological impacts of artificial reefs may outweigh potential economic gains. For example, development of artificial reefs may cause an increase in overall visitation to an area, meaning more visitors to both artificial and natural reefs.
