How can this be an animal? This is a worm. And even though it is blue, this is a Christmas tree worm. These "Christmas tree" structures are actually specialized mouth appendages. Each spiral is composed of feather-like tentacles which are heavily ciliated. These appendages trap prey and transport the food straight towards the worm's mouth. And these worms are annelids. Structure and Function of Annelids Annelids range in length from less than 1 millimeter to over 3 meters. They never attain the large size of some mollusks. Like mollusks, however, they have a coelom. In fact, the annelid coelom is even larger, allowing greater development of internal organs. Annelids have other similarities with mollusks, including: • A closed circulatory system (like cephalopods). • An excretory system consisting of tubular nephridia. • A complete digestive system. • A brain. • Sensory organs for detecting light and other stimuli. • Gills for gas exchange (but many exchange gas through their skin). The segmentation of annelids is highly adaptive. For one thing, it allows more efficient movement. Each segment generally has its own nerve and muscle tissues. Thus, localized muscle contractions can move just those segments needed for a particular motion. Segmentation also allows an animal to have specialized segments to carry out particular functions. This allows the whole animal to be more efficient. Annelids have the amazing capacity to regrow segments that break off. This is called regenera...

annelid, phylum name Annelida, also called segmented worm, any member of a phylum of General features Distribution and abundance Annelids are found worldwide in all types of habitats, especially oceanic waters, fresh waters, and damp soils. Most polychaetes live in the ocean, where they either float, burrow, wander on the bottom, or live in tubes they construct; their colours range from brilliant to dull, and some species can produce light. The feather duster ( Manayunkia speciosa) inhabits the e.g., all marine leeches are parasitic on fish. Size range and diversity of structure The length of annelids varies from a fraction of an inch to more than six metres (about 20 feet). The width may exceed 2.5 centimetres (about one inch) in the contracted state. Free-moving polychaetes and earthworms include the largest species. Leeches attain lengths of about 0.4 metre in the contracted state. Polychaetes The body of free-moving polychaetes (see figure) consists of a head, or prostomium, which may bear two or more eyes; a preoral segment, with such appendages as antennae, tentacles, and palpi (fleshy sensory projections); a trunk divisible into distinct segments; and a tail, or pygidium, which may bear anal cirri (fleshy projections) or plaques and a i.e., fleshy, lateral outgrowths used in feeding,
