The Dwarf Zebra Lionfish is easy to distinguish from the other lionfish species because of the enlarged pectoral fins. The fins are full and fan shaped and the fin membranes extend almost all the way to the end of the rays. They are usually found on sandy areas of reef flats ranging from between 3 meters to 25 meters in Tanzania but can be found down to 80 meters. Dwarf Lionfish feed at night and prey on small fishes and crustaceans and pretty much anything that fits in their mouth. They are ambush predators and move into positions where small fishes are likely to congregate. They use their proportionally large mouths to create a vacuum and suck in and swallow the prey. Being smaller than other Lionfish they go after smaller prey. They will sometimes use their pectoral fins to herd prey into a position where they can trap them. Little is known about their reproduction.
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.
They have feathery pectoral fins that are used to attract smaller prey. On the other hand, same features keep the predators on the safe distance. Lionfish has more than thirteen (up to 18) venomous spines on the back side of the body. Venom is used only for self-defense (lionfish does not hunt using these spikes). Lionfish is a carnivore (meat-eater). It eats various types of fish and crustaceans. They often hunt as an ambush predator (using the factor of surprise). The large mouth of lionfish allows swallowing of the prey in a single bite. They can survive from 5 to 15 years as a diurnal animal (active during the day).
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.
Nudibranchs are grouped with snails and slugs in the class Gastropoda, but they differ from snails by having no shell, or at least a greatly reduced one. As their name implies, nudibranchs are further identifiable by their naked or exposed gills. The gills are easily visible on the backs of most nudibranchs. While appealing to the human eye, the main two purposes of these nudi’s intricate patterns and bright colors are defense and camouflage.
Whale sharks are filter feeders that eat plankton through their gills for much of their nourishment. They also eat squid, krill, and small fish. A whale shark can process more than 6,000 liters of water an hour through its gills. Whale sharks are in no way related to whales. Although they are sharks, they are very docile. A whale shark’s mouth is at the very front of its head—as opposed to the underside of the head like most sharks.
Sea Stars have remarkable regenerative powers, when attacked and damaged by predators they are able to grow new arms. They usually have five arms but have been found with 4 or 6 arms, this may be because more than one arm has been damaged at one time! The eyes see only light and darkness. The mouth is found in the centre of the body on the underside. They possess a cleverly evolved arsenal of hydraulic tube feet connected to an elaborate water-vascular system that encircles the animal's mouth and extends via five radial canals down the centre of each arm. Sea stars move very slowly using their water filled tubes and tube feet that stick out through the skin to hold onto surfaces. Their mouth is underneath, but their prey is absorbed outside their mouths when the sea star sits on its prey and forces out their digestive organs from their stomach
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.
