Notoproctinae

	Notoproctinae ''Notoproctus'' is a genus of marine polychaete worms in the family Maldanidae. It is the only member of the subfamily Notoproctinae. Description ''Notoproctus'' worms are characterized by the presence of cephalic and pygidial plates, a cephalic plate with a low rim, a wide prostomium that forms a low keel, strongly curved nuchal grooves, notochaetae with long and thick capillaries, neurochaetae shaped as acicular spines or reduced uncini in the first four chaetigers (i.e. segments with chaetae), subsequent chaetigers with a row of rostrate uncini, a pygidium with a flat pygidial plate with a low rim, and an anus dorsal to the plate. They have 10 to 17 chaetigers, and some achaetous (i.e. without chaetae) segments before the pygidium. Classification This genus contains 9 species: ''Notoproctus abyssus'' ''Notoproctus godeffroyi'' ''Notoproctus laevis'' ''Notoproctus lineatus'' ''Notoproctus oculatus'' ''Notoproctus pacificus'' ''Notoproctus scutiferus'' ''Notoproct ...

	Maldanidae Maldanidae is a family of more than 200 species of Marine life, marine polychaetes commonly known as bamboo worms or maldanid worms. They belong to the order Capitellida, in the phylum Annelida. They are most closely related to family Arenicolidae, and together form the clade Maldanomorpha. Morphology Maldanid worms have a long and cylindrical body that usually bends at one or both ends. It can be divided into four parts: 1) a head, formed by a Dorsal (anatomy), dorsally positioned prostomium that is fused to the peristomium, sometimes with a flattened cephalic plate; 2) a thorax, formed by the first four wikt:chaetigers, chaetigers (i.e. Chaeta, chaetae-bearing metamery, segments), usually with strong spines; 3) an abdomen, with several longer chaetigers that are often followed by a number of achaetous (i.e. without Chaeta, chaetae) segments; 4) a posterior end, with a pygidium that contains the anus. The maldanid pygidium takes a wide variety of forms such as conical, plate-shaped ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Notochaetae A chaeta or cheta (from Greek χαίτη “crest, mane, flowing hair"; plural: chaetae) is a chitinous bristle or seta found in annelid worms, (although the term is also frequently used to describe similar structures in other invertebrates such as arthropods). Polychaete annelids, ('polychaeta' literally meaning "many bristles") are named for their chaetae. In Polychaeta, chaetae are found as bundles on the parapodia, paired appendages on the side of the body. The chaetae are epidermal extracellular structures, and clearly visible in most polychaetes. They are probably the best studied structures in these animals. Use in taxonomy and identification The ultrastructure of chaetae is fundamentally similar for all taxa but there is vast diversity in chaetal morphology.
