Sea Worms Sea Worms. The sea worms are a large and varied group of animals belonging to a group called annelida. They are segmented worms, and all bear at least some resemblance to the common earthworm. In the ocean, however, the worms have evolved many different appearances. One of the more interesting varieties is the tube worms. These animals form a hard-shelled tube that provides them protection.

12 Surprising Facts About Starfish Sea stars belong to the Phylum Echinodermata. That means they are related to sand dollars (yes, they are a real animal), sea urchins, and sea cucumbers. All echinoderms have five-point radial symmetry, which means that their body plan has five sections (or multiples thereof) arranged around a central disk.

- For other uses, see Sea urchin (disambiguation). Sea urchins or urchins (/ˈɜːrtʃɪnz/), archaically called sea hedgehogs, are small, spiny, globular animals that, with their close kin, such as sand dollars, constitute the class Echinoidea of the echinoderm phylum.

Clamworms Clamworms. A clamworm (Nereis) is a predatory marine polychaete that feeds on small marine animals, planktonic organisms, and detritus from the mud. These strange worms that closely resemble the land-based centipede or millipede actually live in the mud or fine sand of seashores along the West, East, and Gulf Coasts.

Why Is Assessment Important? Asking students to demonstrate their understanding of the subject matter is critical to the learning process; it is essential to evaluate whether the educational goals and standards of the lessons are being met. Assessment is an integral part of instruction, as it determines whether or not the goals of education are being met. Assessment affects decisions about grades, placement, advancement, instructional needs, curriculum, and, in some cases, funding. Assessment inspire us to ask these hard questions: Are we teaching what we think we are teaching?

Worm Classification 1 Annelida – This group is probably the most recognized of the three worm classifications. 2  Phylum Annelida includes some sea worms, but it is mostly comprised of segmented worms such as earthworms. 3  Earthworms are also an unofficial broad classification of worms.he following are the three classifications: 1  Annelida – This group is probably the most recognized of the three worm classifications. 2  Nematoda – This phylum of worms includes roundworms, hookworms and threadworms. 3  Platyhelminthes – The worms in this group are flat or ribbon-shaped.

Nemerteaâ Details For the most part, ribbon worms are bottom dwellers on temperate marine shores, where they burrow in mud or sand or creep about among rocks and seaweeds between tide marks or in shallow waters. Only a few burrow into the deep-sea bottom, sometimes at depths of forty-five hundred feet or more.

Annelida - Segmented Worms There are about 15,000 species in this phylum. The phylum includes earthworms, leeches, and marine worms known as polychaetes. Species in this phylum have metameric bodies. Metameric bodies are divided into segments called annuli.The annuli are covered in tiny hairs called setae. Setae help the worms move.Each segment contains parts of the organism's excretory, circulatory, reproductive, and nervous system! The head and the rear of the body is not segmented. The digestive system of species in this phylum runs the length of the body.Food is taken in at one end of the body and expelled at the other end. Annelids have two sets of muscles that help them move.here are about 15,000 species in this phylum. The phylum includes earthworms, leeches, and marine worms known as polychaetes. Species in this phylum have metameric bodies. Metameric bodies are divided into segments called annuli.

- Segmented worms make up the Phylum Annelida. The phylum includes earthworms, leeches, and a large number of mostly marine worms known as polychaetes.Polychaetes (meaning many bristles) have many bristles on the body, while earthworms and leeches have fewer bristles. Some are parasitic, as the leeches; others filter-feed or prey on other invertebrates.egmented wormsmake up the Phylum Annelida.

- They belong to a group of animals called echinoderms, which means spiny skin. They are related to brittle stars, sea urchins, sea cucumbers, and sand dollars. Sea stars have five arms, or rays, connected to a small round body. Sea stars detect light with five purple eyespots at the end of each arm. The bright orange dot in the center of the body is called the madreporite. This organ pumps water into the sea star's body.

- Annelids are a phylum including earthworms, leeches, polychaete worms, and some other worm groups(3). Annelids are also called segmented worms because a defining feature they all share is a body most of which is divided into segments, each of which contains parts of the basic body systems (2).arthworms, freshwater worms, leeches, and marine worms are all annelids. This group is also called bristle worms because most annelids have tiny chitinous bristles called setae. The setae help terrestrial annelids grip their surroundings, and they aid aquatic forms with swimming.

- Clamworms belong to a family of worms called bristle worms. Bristle worms have segmented bodies. Each segment has a pair of legs, called pseudopodia, which means “false feet.” Tiny hairs or bristles stick out from each of these legs.

- The term “sea lice” is used to refer to two very different groups of marine organisms. In the first sense, they are parasites that attack fish, especially salmon.In the second sense, they are actually the larval form of organisms like jellyfish and sea anemones. Both are of interest to humans, for very different reasons.stormyknight: There is no risk to humans for eating fish with sea lice or to eat fish that have been treated for sea lice. Sea lice live on the outside part of the fish and they feed on the mucus on the skin of the fish.

- The larval worms of Anisakis are eaten by a small shrimplike crustacean, a euphausiid; the first host of Phocanema is a small isopod crustacean that lives on the sea bed. When crustaceans infested with Anisakis or Phocanema are eaten by a fish the larval worms are released into its stomach.

Worm Classification Worms are in a very broad category that is not officially classified in any scientific sense. While most worms are limbless invertebrates, some worms are actually reptiles or amphibians. Many other animals called worms are simply insect larvae that have yet to metamorphose into their adult stage. Nematoda – This phylum of worms includes roundworms, hookworms and threadworms. 2  Many roundworms are parasites and can cause a variety of problems for people and pets. 3  Threadworms live on the ground in damp soil, mossy areas or in decaying vegetation.
