Manatee Research Paper

Description The Hammerhead shark is a long, odd looking animal. on average, they 11.5 feet long, and weigh about 1,000 pounds. The odd shaped head they have is called a cephalofoil, and it allows for 360o vision. The Hammerhead shark has very different physical features from most other sharks. Habitat The Hammerhead shark can be found throughout various places globally, and usually lives in warm tropical and coastal waters along continental shelves.

However the expected lifespan of one is about 15 years. If the largemouth bass is in captivity, they usually get to be about 11 years old. (Boschung, et al., 2004) They usually prefer to live in shallow that is no deeper than three meters. Although sometimes you may find some of them living in the deeper part of the water. The largemouth bass have the ability to hide from their prey and provide protection against their predators through the process of abundant vegetation.

Well, most of this secret lays in their feet. They have long toes with fringes of skin in between them that unfurl in water, this creates a air bubble that prevents them from sinking. However, they have to pull their feet up before the air bubble sinks and gravity pulls them down. Strong bones was usually a good thing, but these lizards have evolved hollow bones that prevent them from sinking. Some of the secret also lies within their tail, while running they hold their tail in the air to counterbalance their upright posture and to reduce drag.

However, most caught off piers are fish under 5 kg in weight. California yellowtail are solitary or they may occur in small groups. The schools of juveniles are generally found in offshore waters, often near or beyond the continental shelf. The species is a powerful swimmer that is adapted to a pelagic life style and hence is prized by anglers. These fish are equipped with sensory cells (neuromasts) which are located

It does so by keeping its outer layer of skin moist so the oxygen can pass through easily. The jellyfish, a member of the Scyphozoa class, acts similarly and absorbs oxygen easily through its skin. This method, used by both the earthworms and jellyfish, gets oxygen into the body but isn’t always the most efficient way. The lion, a mammal, has a more advanced way of respiration and has an entire

A Study Case of Amazonian Calf Interactions Introduction The Amazonian manatee is a very well known and loved species of manatee. Out of all of the Manatee species the Amazonian manatee is the smallest that utilizes only fresh water habitats. It has a fairly limited habitat that falls in the Amazonian Basin 's rives and lakes. They play an important role as a ecosystem primary producer. Unfortunately the species is considered Vulnerable on the Red List of Threatened species of the International Union for Conservation of Nature due to human interaction.

*They have relatively low metabolic rates. *All turtles have a bony shell consisting of (i) a carapace formed from costal bones with fused ribs, neural bones with fused thoracic vertebrae, and peripheral bones; (ii) a plastron consisting of interclavicle, clavicle, and three to five additional pairs of dermal bones sutured together. *The carapace and plastron are firmly united along their edges, but have apertures for the head, tail, and fore and hind limbs. *The limbs and tail can almost always be withdrawn at will under the shelter of the thoracico-abdominal case

Adaptation to live in the habitat lack of oxygen A. Crayfish: Crayfish lives in fresh water stream, which is an aquatic environment. The oxygen level in fresh water upper stream is higher than the lower stream, but the oxygen concentration is still low. The gills of crayfish are much bigger than the size at first glance. They occupied under the cephalothorax carapace in branched-shape and provided a large surface area to volume ratio to carry out gas exchange. Fresh water will be pulled into the cavity by the movement of the “gill bailers”.

Migrating Manatees. Some description about the manatee are, manatees are big and gray, they are very large and they weigh 800 to 1200 pound, they are 10 feet long and algae grows on there back. Manatee habitats are very interesting. Manatees live in north american east coast, shallow slow moving rivers, saltwater bays, canals, and the coastal areas. They eat seagrass and freshwater vegetation.

While sharks are perhaps the most well-known member of the taxonomic class elasmobranch, stingrays also represent a relatively large and important percentage of the phylum. Traditionally, however, this class of fish has largely been overlooked within the scientific community and the general population, resulting in the existence of little reliable information on these fish. With Caribbean islands moving increasingly towards a reliance on stingray populations to support their tourism industry, and the development of a pet trade centered on freshwater stingray populations, though, this gap in scientific knowledge and the drastic consequences that can accompany it are becoming increasingly exposed. For example, work with the Cayman Islands southern
