The Amphitrite worm lives in a solid, sand-encrusted tube and can reach a length of forty centimeters. The three brilliant red bushy gills and a spread of long peach-colored tentacles above them are all that are visible. The tentacles are always moving, looking for food particles, and they can reach a length of forty centimeters.
Lugworms and black lugs belong to the genus Arenicola, which is commonly referred to as sandworms. On the coasts of North America and Humboldt Bay, California, A.cristata is the most common warm-water lugworm. While Arenicola marina is primarily found in Europe, including Norway, A. caroledna is more common in China and Japan. Only Southern Africa
The genus Sabellaria belongs to the Sabellariidae family of marine polychaete worms. Sabellaria alveolata is the type species (Linnaeus, 1767). These sedentary worms construct tubes out of pieces of shell and sand to survive. When found in large quantities, certain species known as honeycomb worms can create reefs on rocks and other hard surfaces. They
INTRODUCTION The phylum Bryozoa, or Polyzoa, or Ectoprocta are the greatest and most common of the three lophophore phyla. Colonial sessile animals such as Cnidaria and Ectoprocta were for a long time confused by early naturalist sea plants and named them as zoophytes. In 1827 Grant found that ectoprocta are highly organised than true polyps

INTRODUCTION The Entoprocta or Endoprocta are group of small sessile aquatic animals. In which the body cavity is believed to be pseudocoel. They were formerly include in the phylum Bryozoa which however are true coelomate animals. Members of phylum Entoprocta were known as early as 1774, when Pallas describe a colony of Pedicellina. In 1870
INTRODUCTION Phoronida are long and thin worm like organisms. All phoronids reproduce sexually. Some of them are hermaphrodite while other aredioecious. Fertilization is internal as well as external. Intermediate larval stage is present. This species generally live in coastline of mostly all oceans and seas except the Antarctic ocean. Phoronids are generally algae feeder and

The genus Lepisma comprises primitive insects that belong to the family Lepismatidae and order Zygentoma. The silverfish (L. saccharinum), the most well-known species in the genus Lepisma, is a worldwide species that prefers moist environments, hides in cracks, and is typically found in human homes. In some cases, it can become a household annoyance. Although
Solifuges, or sun spiders, belong to the genus Galeodes. This genus has around 200 species that are distributed throughout Asia, southeastern Europe, and northern Africa. They are mostly nocturnal and found in dry environments, just like other solifuges. They are not as robust or as dark and contrastingly colored as some other solifuges, and they
Long before dinosaurs walked the Earth, Limulus was already crawling along ancient seafloors — and it hasn’t changed much since. Commonly known as the horseshoe crab, Limulus is one of the oldest surviving animal lineages on the planet, with a fossil record stretching back roughly 450 million years. Despite its name, it isn’t a crab
Male spiders (Araneus) in this genus are typically 1⁄3 to 1⁄4 the size of females, making them possibly the most blatant example of sexual dimorphism in the whole orb-weaver family.
The predatory arachnids known as scorpions (Palamnaeus) have eight legs, two grabbing pincers, and a slender, segmented tail that always ends with a stinger and is frequently carried in a distinctive forward curve over the back.
Peripatus is zoologically very interesting, because it exhibits both arthropod and annelid characters as under. Peripatus is supposed to be the connecting link between Annelida and Arthropoda.
The class Diplopoda, which derives its name from the Latin mille, which means “thousand,” and pes, which means “foot,” is the formal term for the group of arthropods known as Julus (millipedes).
There are several centipede species in the genus Scolopendra that are found in both milder temperate regions and tropical regions of the planet. The species differ greatly in size and color. The majority of scolopendra are enormous centipedes
Crabs in the genus Carcinus (Greek: Καρκίνoς Karkinos) include the significant invasive species Carcinus maenas and the Mediterranean Sea-endemic species C. aestuarii.
The little, sand-burrowing decapod crab species Hippa adactyla inhabits the shores of the Indo-West Pacific. It can be found in the swash area of the intertidal zone on bare sandy beaches.
Commonly identified as belonging to the genus Pagurus, Eupagurus is a genus of marine hermit crabs in the Paguridae family. They are distinguished by their asymmetrical, soft, and curled abdomens, which necessitate sheltering in empty snail shells. These decapods are found in marine habitats all over the world, frequently coexisting with sea anemones.
Crayfish vs Lobster : Differences Explained – The fact that lobsters are sometimes referred to as crayfish in some places only serves to further confuse the two species. They do appear strikingly same, so it’s simple to make the mistake. Both have big pincers and robust exoskeletons, and they both live in water. In actuality, however, they belong to two distinct species.
Palinurus is a genus of lobsters in the family Palinuridae, native to the eastern Atlantic Ocean, the Mediterranean Sea and the western Indian Ocean. A 110 million year old fossil, recognizable as a member of the genus Palinurus, was discovered in a quarry in El Espinal, Chiapas state, Mexico, in 1995 and named P. palacesi.
Astacus astacus (commonly known as the European crayfish, noble crayfish, or broad-legged crayfish) is a freshwater decapod native to Europe from France to Russia to Scandinavia
