		Roach Anatomy ^Votes:0 Privacy Policy Part 2 ESOPHAGUS: A cockroach esophagus (a fancy word for throat) isn't as long as a human's, but it gets the job done. Food travels from the mouth, through the esophagus to the stomach. CROP: The crop is a section at the end of the esophagus used to store food for a while. If a cockroach doesn't chew its food properly, a second set of teeth in its digestive tract, also called a gizzard, gives it another chance. GASTRIC CAECEA: If cockroaches couldn't digest their food, they'd explode! The gastric caecea are little sacks inside a cockroach that keep germs and enzymes available to help a cockroach digest its food. MIDGUT: The middle part of the intestine where the cockroach absorbs nutrients is called the midgut. MALPIGHIAN TUBULES: You say po-tay-toe, I say po-tah-to. You sa Read More Go to Site

		SharkFriends Dolphin and Porpoise Page ^Votes:0 ~ SharkFriends Dolphin and Porpoise Page ~ Just click the name of the dolphin or porpoise, on the image map below, that you are interested in learning more about... Images on the dolphin/porpoise pages are copyrighted. * Cool Dolphin Trivia: Dolphins can move their eyes independently from each other, similar to a gecko lizard, this allows a dolphin to be able to see from different angles at the same time which helps them when looking out for predators. Dolphins also sleep with one eye open... so half their brain is resting while the other half stays on alert for predators. Read More Go to Site

		SharkFriends Harp and Harbor Seals Page ^Votes:0 ~ Harp & Harbor Seals ~ HARP SEAL Natural History: Adult male harp seals grow to about 1.7 m and 130 kg; females are slightly smaller. Gregarious by nature, harp seals haul out in dense herds to give birth and moult. Females and males reach sexual maturity at approximately 4-6 years of age. A single pup weighing about 10 kg (22 lbs) is born each year from mid February to March. Mating occurs after the pups are weaned at about 12 days. After mating, adult males are joined on the moulting patches by immature and non-breeding seals, followed by adult females. Harp seals consume a wide range of prey species and their diet appears to vary with age, season, location and year. Harp seals can live up to 30 years. Distribution and Habitat: Harp seals inhabit the North Atlantic and Arctic Oceans fro Read More Go to Site

		SharkFriends Manatee Page ^Votes:0 ~ The Manatee ~ In the quiet backwaters, just below the surface, lurks the fabled manatee, a cuddly "sea cow" that often relaxes in the shallow water. Human onlookers delight in spotting one, especially when it suddenly takes a splash. Manatees are surprisingly agile and can perform somersaults, tail stands and other graceful underwater maneuvers. These large, seal-shaped mammals can reach a length of 4.5 meters and weigh more than 1,000 kilograms. No wonder. Manatees eat seagrass and other submerged vegetation for 6 to 8 hours a day. The surface layer of their finely wrinkled skin is continually sloughing off, possibly to reduce the build-up of surface algae. The whiskered mammals live in the mouths of jungle rivers, lagoons and bays from Florida to Brazil, including several Caribbean isl Read More Go to Site

		SharkFriends Octopus Page ^Votes:0 ~ The Octopus ~ An octopus has a soft body and eight arms. Each arm has two rows of suction cups. If it loses an arm, it will eventually regrow another arm. It has blue blood. An octopus has an eye on each side of its head and has very good eyesight, but an octopus cannot hear. Octopi live on the ocean floor. They are mainly shy, solitary animals. The octopus swims by a kind of jet propulsion, spewing out water from its body to propel itself through the water. There are over 100 different species of octopi. The Giant Octopus is the biggest octopus and can measure up to 23 ft from arm tip to arm tip, and can weigh up to 400 pounds. The smallest octopus is the Californian octopus, which only measures about 3/8 inches long. The only poisonous octopus is the blue ring octopus. Octopi eat small Read More Go to Site

		SharkFriends Sea Horse Page ^Votes:0 ~ Sea Horse ~ NAME: The name is derived from the resemblance of the head to that of a horse. DESCRIPTION: A sea horse has long, tubular jaws much like a snout. The body is compressed, with an elongated tail, and the integument (external covering) is a series of large, rectangular bony plates, with a series of spines and projections along the lines of juncture. These spines, together with the divided, streamerlike fins of some species, give them a strong resemblance to the seaweeds among which they live. SPECIES AND LOCATION: About 30 species of sea horses are found in various warm and temperate seas. Sea horses are of the same family as the pipefish. All keep near the shore, often developing in brackish water. BEHAVIOR: Sea horses, like pipefish, have unusual breeding habits. Following mat Read More Go to Site

		SharkFriends Sea Otter Page ^Votes:0 ~ The Sea Otter ~ The sea Otter is perhaps the best known of the otter family. When you think of an otter, most probably the first thing that comes to your mind is the cute, cuddily face of the Southern Sea Otter. There are, in fact, two kinds of Sea Otters, Southern Sea Otters, which live more to the south than Alaskan Sea Otters. Other than the distinction in size and habitat, they are very much alike. Sea Otters are unique marine mammals in that they use tools such as rocks to open their prey such as the shells of abalone. These social otters float in rafts in the Pacific Ocean just offshore. They have extraordinarily dense fur to keep them warm and are the heaviest otter species. Size: From the head to the body it is approximately 22 inches to 52 inches, the tail is 5 inches to 13 inch Read More Go to Site

		SharkFriends Sea Snake Page ^Votes:0 ~ Sea Snakes ~ NAME: Sea snake is the common name for certain marine members of a family of venomous snakes. HABITAT: Sea snakes inhabit tropical waters from the Indian ocean to the Pacific ocean. Sea snakes are particularly abundant in the Persian Gulf and the Bay of Bengal. SIZE: Most sea snakes are not large, ranging from about 1.6 to 3.3 feet in length, although Stokes's sea snake can reach nearly 6 and a half feet. REPRODUCTION: One group of sea snakes, sometimes called the true sea snakes, give birth to live young and lack the enlarged ventral scales typical of most terrestrial snakes. The other group, sometimes referred to as seakraits, lay eggs; because they must leave the water to deposit their eggs, they retain straplike ventral scales, although these may be smaller than those of Read More Go to Site

		SharkFriends Sea Turtle Page ^Votes:0 ~ Sea Turtles ~ Sea turtles are perfectly adapted for life in the oceans. They are large long-lived animals (50 to 100 years?) with relatively streamlined shells. The swimming limbs are held out to the sides more than downwards, making movement on land very difficult and awkward. The front flippers are generally elongated and provide the main propulsive force. The hind flippers are large and spadelike and the females use these when digging their nests in the sand. Sea turtles absorb a great deal of salt from their diet and when they drink sea water they have salt glands in their eye sockets which enables them to excrete excess salt. The salt concentration can be twice as much as in sea water. When female turtles nest they are said to cry, but in reality, they are excreting salt from the gl Read More Go to Site

		Yucky: Roach Anatomy ^Votes:0 Privacy Policy Part 1 EYE: Cockroaches have "compound eyes" which allow them to see simultaneously in almost all directions around its body. Each cockroach eye is made up of 2,000 individual lenses. In contrast, human eyes have only one lens. Weird fact: cockroaches cannot see in red light, but see in green light very well. LEG: Hairs on the legs of a cockroach provide an extra sense of touch. ANTENNAE: Sniff, sniff. Antennae, or feelers, provide roaches with a sense of smell. Male cockroaches have special sense receptors that allow them to smell the odor produced by a female when she is looking for a mate. CERCI: Cerci are the two little hairs on the rear end of a cockroach. They act like a motion detector. When something tries to sneak up on a cockroach, the cerci detects the slightest b Read More Go to Site
