Salt Marshes‚Mangroves‚and Coral Reefs Salt Marshes • Salt marshes are found along low lying coastlines where boggy ground is flooded by sea water either daily or less frequently. • Many UK salt marshes have been reclaimed for farm land‚ but those that remain provide valuable habitats where salt-tolerant plants grow and birds nest. Salt marshes also pay a vital role for coastal protection‚ they contain creeks which allow tidal waters to flow both in and out which reduces the wave energy

They eat corals‚ sponges‚ sea urchins‚ algae‚ crustaceans and other small fish. Requirements for habitat: They live in the sub-tropical

otters like to stay around and in the kelp forest looking for sea urchins‚ their favorite food. The giant kelp forests provide food and habitat for hundreds of species including fish and invertebrate animals that belong to several groups including crustaceans‚ starfish‚ mollusks‚ anemones‚ sponges and tunicates‚ and other species in water column. Upon the sinking of the decomposing kelp (detritus) to the depths of the ocean‚ it provides food for deep sea animals. The shading created by well-established

Human Eye Vs. Animal EyeBy:Andrea Torres ABSTRACT The tapetum lucidum is an evolutionary advantage for animals. It enables animals to see in dimmer light than the animal would otherwise be able to see in. The tapetum lucidum is useful to animals‚ but it also has a use to humans. Human beings use the tapetum lucidum to scan for reflected eye-shine‚ in order to detect and identify the species of animals in the dark and to send trained search dogs and search horses out at night.

Over the past 10-20 years‚ some reports indicate that populations have declined 75% or greater and have become dangerously low.The bird also lays

Characteristics of the Phylum Arthropoda The segmented bodies are arranged into regions‚ called tagmata (e.g.‚ head‚ thorax‚ abdomen). The paired appendages (e.g.‚ legs‚ antennae) are jointed. They posses a chitinous exoskeletion that must be shed during growth. They have bilateral symmetry. The nervous system is dorsal (belly) and the circulatory system is open and ventral (back). Arthropod Groups (taxa) The arthropods are divided into two large groups that exist today: The Chelicerates

becomes sharply hooked backwards. Pectoral flippers may also have a definite "elbow" and curve back sharply on their leading edge. Diet & Behaviour: Stomach contents of stranded hourglass dolphins have revealed that they feed on small fish‚ crustaceans‚ and squid. Usually found in groups of 7-10‚ these dolphins are not at all shy when encountered and often bow ride‚ even approaching slower moving vessels. Sometimes they’ll spin while riding the waves. When they bow ride‚ they swim in long low

cowfish has longer horns as the name suggest. Cowfish grow to approximately 18-19 inches or about 45-48 cm. The longhorn cowfish can be found from Japan to Australia. The scrawled cowfish is found in the Atlantic. They feed on invertebrates and crustaceans. In captivity they will eat chopped meaty foods and marine algae. If kept in a reef aquarium they are likely to eat the inhabitants. They will also eat frozen food. Longhorn Cowfish Cowfish are slow moving fish due to their body shape. They
