Manatees are more closely related to the elephant than they are to other marine creatures. The cow-like creatures are thought to have inspired mermaid legends. Manatees typically come up for air every 5 minutes. However, when it is resting, the aquatic mammal can hold its breath for up to 20 minutes. Manatees swim at an average of 5 miles an hour, which is why algae and barnacles can often be found on the backs of manatees. Manatees don’t have the neck vertebra that most other mammals have, meaning that they must turn their entire bodies if they want to look around.
Barrier bars or beaches are exposed sandbars that may have formed during the period of high-water level of a storm or during the high-tide season. During a period of lower mean sea level they become emergent and are built up by swash and wind-carried sand; this causes them to remain exposed. Barrier bars are separated from beaches by shallow lagoons and cut the beach off from the open sea.
Across the world statues have been sunk into the oceans for a variety of reasons—as memorials, to offer protection to a fragile marine environment, or simply as art. Colored with algae and populated by coral, some of the statues have become tourist destinations in their own right.
Despite having a hairy appearance, the “hairs” of a Hairy Frogfish are actually skin appendages or spinules which cover the frogfish’s body, head and fins. These spinules can be copious and long or very short or even almost invisible. Hairy frogfish are extremely good at hiding in plain sight and are able to change their color to match their surroundings.
Common sandpiper has long, straight bill, small body and short legs. Common sandpiper spends a lot of time on the ground. Its head and rear part of the body are constantly bobbing while it walks or feeds on the ground. This unusual behavior is known "teetering". Common sandpiper has stiff-winged style of flying. Its flight consists of rapid, shallow wing beats combined with short glides.
Research on sharks has allowed knowing from their origin and evolution to the applications that they have in different ambits of the human life. It is tough to know about the beginning of the research but it seems that the oldest casual investigations date back to the time of the Renaissance when people assumed that the fossils of the large teeth embedded in the rocks came from dragons or snakes.
Porcupinefish has spines on the head and body that lay flat, but when threatened they can inflates its body by swallowing water, inflating like a "football with spikes" so the spines are facing outwards to deter prey. The have a plated mouth structure for crushing shells.
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.
