The acorn worms or Enteropneusta are a hemichordate class of invertebrates consisting of one order of the same name. However, the last decade has seen the description of a new family, the Torquaratoridae, evidently limited to the deep sea, in which most of the species crawl on the surface of the ocean bottom and alternatively rise into the water column, evidently to drift to new foraging sites. The body is made up of three main parts: an acorn- shaped proboscis, a short fleshy collar that lies behind it, and a long, worm- like trunk. The creature's mouth is located at the collar behind the proboscis. Some produce a bromide compound that gives them a medicinal smell and might protect them from bacteria and predators. Acorn worms move only sluggishly, using ciliary action and peristalsis of the proboscis. Others feed on organic material suspended in the water, which they can draw into the mouth using the cilia on the gill bars. This diverticulum was once thought to be homologous with the notochord of chordates, hence the name . The mouth opens posteriorly into a pharynx with a row of gill slits along either side. The remainder of the digestive system consists of an oesophagus and intestine; there is no stomach. Digestion occurs in the intestine, with food material being pulled through by cilia, rather than by muscular action. The water then flows out the animal's gills which are on its trunk. Thus, the acorn worm breathes about the same way as fish. Circulatory system. A dorsal blood vessel in the mesentery above the gut and delivers blood to a sinus in the proboscis that contains a muscular sac acting as a heart. Unlike the hearts of most other animals, however, this structure is a closed fluid- filled vesicle whose interior does not connect directly to the blood system. Nonetheless, it does regularly pulsate, helping to push blood through the surrounding sinuses. This set of structures is referred to as a glomerulus and may have an excretory function, since acorn worms otherwise have no defined excretory system. Temperatures for Vermicomposting. Vermicomposting, a living process, involves special compost worms called red wigglers or Eisenia fetida. Start studying Flowers.

Surrounded by large pots of blooming desert roses. From the proboscis, blood flows into a single blood vessel running underneath the digestive tract, from which smaller sinuses supply blood to the trunk, and back into the dorsal vessel. Each slit consists of a branchial chamber opening to the pharynx through a U- shaped cleft and to the exterior through a dorso- lateral pore (see diagram below). Cilia push water through the slits, maintaining a constant flow. The tissues surrounding the slits are well supplied with blood sinuses. While the ventral cord runs only as far as the collar, the dorsal cord reaches into the proboscis, and is partially separated from the epidermis in that region. This part of the dorsal nerve cord is often hollow, and may well be homologous with the brain of vertebrates. In acorn worms, it seems to be primarily involved with coordinating muscular action of the body during burrowing and crawling. There are, however, numerous nerve endings throughout the skin. They have a circulatory system with a heart that also functions as a kidney. Therefore, acorn worms are sometimes said to be a link between classical invertebrates and vertebrates. Some also have a postanal tail which may be homologous to the post- anal tail of vertebrates. An interesting trait is that its three- section body plan is no longer present in the vertebrates, except for the anatomy of the frontal neural tube, later developed into a brain which is divided into three main parts. This means some of the original anatomy of the early chordate ancestors is still present even if it is not always visible. One theory is that the three- part body originates from an early common ancestor of all the deuterostomes, and maybe even from a common bilateral ancestor of both the deuterostomes and protostomes. They live in U- shaped burrows on the sea- bed, from the shoreline down to a depth of 1. The worms lie there with the proboscis sticking out of one opening in the burrow. Acorn worms are generally slow burrowers. To obtain food, many acorn worms swallow sand or mud that contains organic matter and microorganisms in the manner of earthworms (this is known as deposit feeding). At low tide, they stick out their rear ends at the surface and excrete coils of processed sediments (casts). Another method that some acorn worms use to obtain food is to collect suspended particles of organic matter and microbes from the water. This is known as suspension feeding. They have paired gonads, which lie close to the pharynx and release the gametes through a small pore near to the gill slits. The female lays a large number of eggs embedded in a gelatinous mass of mucus, which are then externally fertilized by the male before water currents break up the mass and disperse the individual eggs. Singh. In most species, the eggs hatch into planktonic larvae with elongated bodies covered in cilia. In some species, these develop directly into adults, but in others, there is a free- swimming intermediate stage referred to as a tornaria larva. These are very similar in appearance to the bipinnaria larvae of starfishes, with convoluted bands of cilia running around the body. Since the embryonic development of the blastula within egg is also very similar to that of echinoderms, this suggests a close phylogenetic link between the two groups. The larvae eventually settle down and change into tiny adults to take on the burrowing lifestyle. A few species, such as Saccoglossus kowalevskii, lack even the planktonic larval stage, hatching directly as miniature adults.
