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.
Whales have HUGE mouths, extending to their belly buttons! This allows them to swallow a volume of water larger than themselves. Their throat stretches down to their navel. Tongue is the size of an elephant. You and 400 of your friends could fit in its mouth! Whales can be divided into two groups: the toothed whale and baleen whale.
Water Lilies are a fresh water plant, with about 70 species in total. Although most water lily species prefer the still waters of ponds and lakes, some can be found growing in slow-flowing rivers and creeks. Most species of water lilies have rounded, variously notched, waxy-coated leaves on long stalks that contain many air spaces and float in quiet freshwater habitats. The stalks arise from thick, fleshy, creeping underwater stems that are buried in the mud.
Dolphins do not have gills like fish. Dolphins need to breathe oxygen from the air but also remain in the water. Jumping out of the water, allows the dolphin to remain wet, while also taking in oxygen. Dolphins jump out of the water for fun, to increase visibility, to remove parasites, and to improve navigation.
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.
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.
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.
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.
The blue marlin is one of the open ocean's fastest, strongest predators and one of the most highly sought after game fishes everywhere that it lives. Reaching weights of at least 1800 pounds (~820 kg) and lengths of more than 16 feet (~5 m), the blue marlin is one of the largest species of bony fishes. Because blue marlin undergo such an amazing transformation in size (from being nearly microscopic to being one of the largest open ocean predators), they eat a wide variety of prey, throughout their lifetimes.
Manta rays have approximately 300 rows of skin-covered teeth in its lower jaw. Their skeleton is composed of cartilage and not bone. Their tails lack skeletal support and are shorter than their disc-like bodies. Their tails also lack venomous tail spikes that all other rays have. Manta rays must swim continuously to keep oxygenated water passing over their gills. They can swim up to 24 kilometers (15 miles) per hour. Mantas visit cleaning stations on coral reefs for the removal of external parasites. The ray adopts a near-stationary position close to the coral surface for several minutes while the cleaner fish consume the attached organisms.
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.
