Our animal is the Bibillius bobois‚ also known as the Bibi Bobois. The phylum our animal comes from is annelisa. What makes our annelid so unique is the way it protects itself‚ keeps predators away‚ reproduces‚ and the way it communicates. The defense mechanisms of the Bobois are especially unique. During the winter the Bobois produces a thick coat of gray slime that will cover its body to create a slimy shell. This slime protects it from cold temperatures by using the Greenhouse Effect to absorb

either vertebrate or invertebrate‚ which lives in water for most or all of its life.[1] Some examples of invertebrates are coelenterates. This phylum consists of jellyfish‚ anemones‚ corals‚ and hydras. Another type of invertebrate aquatic animal is the annelids which are segmented worms. There are three different classes they are polychaetes‚ oligochaetes‚ and hirudinea.[2] It may breathe air or extract its oxygen from that dissolved in water through specialised organs called gills‚ or directly through

shells are empty because the animal has died and the soft parts have been eaten by another animal or have rotted out. Apart from mollusk shells‚ other shells that can be found on beaches are those of barnacles‚ horseshoe crabs and brachiopods. Marine annelid worms in the family Serpulidae create shells made of calcareous tubes cemented onto other surfaces. The shells of sea urchins are called tests‚ and the moulted shells of crabs and lobsters are called exuviae. While most seashells are external‚ some cephalopods have

cells have an equal opportunity for nourishment and removal of their waste products. However‚ even closed circulatory systems differ as we move further up the evolutionary tree. One of the simplest types of closed circulatory systems is found in annelids such as the earthworm. Earthworms have two main blood vessels -- a dorsal and a ventral vessel -- which carry blood towards the head or the tail‚ respectively. Blood is moved along the dorsal vessel by waves of contraction in the wall of the vessel
