Bryozoa are a phylum of aquatic invertebrate animals. About 0.5 millimetres long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a "crown" of tentacles lined with cilia. Most marine species live in tropical waters, but a few occur in oceanic trenches, others are found in polar waters. One class lives only in a variety of freshwater environments, a few members of a marine class prefer brackish water. 5869 living species are known. One genus is solitary and the rest are colonial; the phylum was called "Polyzoa", but this term was superseded by "Bryozoa" in 1831. Another group of animals discovered subsequently, whose filtering mechanism looked similar, was included in "Bryozoa" until 1869, when the two groups were noted to be different internally; the more discovered group was given the name Entoprocta, while the original "Bryozoa" were called "Ectoprocta". However, "Bryozoa" has remained the more used term for the latter group. Individuals in bryozoan colonies are called zooids, since they are not independent animals.
All colonies contain autozooids, which are responsible for excretion. Colonies of some classes have various types of non-feeding specialist zooids, some of which are hatcheries for fertilized eggs, some classes have special zooids for defense of the colony; the class Cheilostomata has the largest number of species because they have the widest range of specialist zooids. A few species can creep slowly by using spiny defensive zooids as legs. Autozooids supply nutrients to non-feeding zooids by channels. All zooids, including those of the solitary species, consist of a cystid that provides the body wall and produces the exoskeleton and a polypide that contains the internal organs and the lophophore or other specialist extensions. Zooids have no special excretory organs, the polypides of autozooids are scrapped when the polypides become overloaded by waste products. In autozooids the gut is U-shaped, with the mouth inside the "crown" of tentacles and the anus outside it. Colonies take a variety of forms, including fans and sheets.
The Cheilostomata produce mineralized exoskeletons and form single-layered sheets which encrust over surfaces. Zooids of all the freshwater species are simultaneous hermaphrodites. Although those of many marine species function first as males and as females, their colonies always contain a combination of zooids that are in their male and female stages. All species emit sperm into the water; some release ova into the water, while others capture sperm via their tentacles to fertilize their ova internally. In some species the larvae have large yolks, go to feed, settle on a surface. Others feed for a few days before settling. After settling, all larvae undergo a radical metamorphosis that destroys and rebuilds all the internal tissues. Freshwater species produce statoblasts that lie dormant until conditions are favorable, which enables a colony's lineage to survive if severe conditions kill the mother colony. Predators of marine bryozoans include nudibranchs, sea urchins, crustaceans and starfish.
Freshwater bryozoans are preyed on by snails and fish. In Thailand, many populations of one freshwater species have been wiped out by an introduced species of snail. A fast-growing invasive bryozoan off the northeast and northwest coasts of the US has reduced kelp forests so much that it has affected local fish and invertebrate populations. Bryozoans have spread diseases to fish fishermen. Chemicals extracted from a marine bryozoan species have been investigated for treatment of cancer and Alzheimer's disease, but analyses have not been encouraging. Mineralized skeletons of bryozoans first appear in rocks from the Early Ordovician period, making it the last major phylum to appear in the fossil record; this has led researchers to suspect that bryozoans arose earlier but were unmineralized, may have differed from fossilized and modern forms. Early fossils are of erect forms, but encrusting forms became dominant, it is uncertain. Bryozoans' evolutionary relationships to other phyla are unclear because scientists' view of the family tree of animals is influenced by better-known phyla.
Both morphological and molecular phylogeny analyses disagree over bryozoans' relationships with entoprocts, about whether bryozoans should be grouped with brachiopods and phoronids in Lophophorata, whether bryozoans should be considered protostomes or deuterostomes. Bryozoans and brachiopods strain food out of the water by means of a lophophore, a "crown" of hollow tentacles. Bryozoans form colonies consisting of clones called zooids that are about 0.5 millimetres long. Phoronids resemble bryozoan zooids but are 2 to 20 centimetres long and, although they grow in clumps, do not form colonies consisting of clones. Brachiopods thought to be related to bryozoans and phoronids, are distinguished by having shells rather like those of bivalves. All three of these phyla have a coelom, an internal cavity lined by mesothelium; some encrusting bryozoan colonies with mineralized exoskeletons look like small corals. However, bryozoan colonies are founded by an ancestrula, round rather than shaped like a normal zooid of that species.
On the other hand, the founding polyp of a coral has a shape like that of its daughter polyps, an
HMS Lennox was a Laforey-class destroyer built for the Royal Navy during the 1910s. The Laforey class were improved and faster versions of the preceding Acasta class, they displaced 965–1,010 long tons. The ships had an overall length of 268 feet 10 inches, a beam of 27 feet 8 inches and a draught of 10 feet 6 inches. Lennox was powered by two Parsons direct-drive steam turbines, each driving one propeller shaft, using steam provided by four Yarrow boilers; the turbines gave a maximum speed of 29 knots. The ships carried a maximum of 280 long tons of fuel oil that gave them a range of 1,750 nautical miles at 15 knots; the ships' complement was 74 ratings. The ships were armed with three single QF 4-inch Mark IV guns and two QF 1.5-pounder anti-aircraft guns. These latter guns were replaced by a pair of QF 2-pounder "pom-pom" anti-aircraft guns; the ships were fitted with two above-water twin mounts for 21-inch torpedoes. They were equipped with rails to carry four Vickers Elia Mk IV mines, although these rails were never used.
Lennox was laid down at William Beardmore and Company's Clydebank shipyard as Portia on 14 November 1912. On 30 September 1913, the Admiralty ordered that the L-class be renamed with names beginning with the letter "L", Portia was renamed Lennox, she was launched on 17 March 1914 on completed in July that year. On commissioning, Lennox joined the 3rd Destroyer Flotilla, based at The Nore. On the outbreak of the First World War this Flotilla became part of the Harwich Force, under the overall command of Commodore Reginald Tyrwhitt, serving in the North Sea, but capable of reinforcing either the Grand Fleet or forces in the English Channel as required. Lennox saw action including the Battle off Texel. On 6 May 1916, Lennox accidentally collided with a seaplane carrier. Damage was insignificant for both ships, however. Caruana, J..

A hip piercing is a piercing in the pelvic area through the skin near the hip bone. Hip piercings are done in couplets with one on each hip, but it is not unusual to see only one. Hips piercing are a type of surface piercing. Microdermals or skin divers can be implanted in the hip area to give a similar appearance; this piercing is fitted with a surface barbell. This type of jewelry is surgical steel or titanium, with two 90 degree angles that can be shaped in various ways to better fit the anatomy of the piercing; some artists use Tygon jewelry. This is a type of plastic, said to reduce stress on the piercing because the long surface bars are better; this is because more skin is pierced and the piercing is less superficial which reduces the risk of rejection. Skin divers and dermal anchors are becoming more common in hip piercings due to their lower rejection rate and higher longevity than surface bars. Hip piercings heal through the dropout process. For Microdermal implants, there are two ways.
One way is with a needle, the other is with a dermal punch. With the needle, the area, going to be pierced is first sterilized with a surgical scrub; the area is pierced, unlike other conventional piercings, the needle punctures your skin in an L shape rather than a straight puncture. This pouch is where the anchor of the dermal piercing will be placed; this jewelry pincers called forceps. The jewelry is screwed into the plate. For the dermal punch, the process is similar to the needle, rather than making the L shape in the skin by separation of the skin, the punch removes skin and tissue to create the space. Using the dermal punch is more protective because it prevents the piercing from going too deep into the skin; this method is more common because it is quicker and less painful than the difficult needle puncture. For surface piercings, the process is different. Rather than puncturing one piece of jewelry into the skin at a time, a surface piercing sends a barbell through a hollow tunnel right under the surface of your skin.
Just like the micro dermal piercing, there are two methods to this process. One includes the use of a needle, the other utilizes a scalpel. With a needle, the surface piercing of the hip is done just like any other place on the body such as a nose piercing, or ear piercing. Pinching the skin together allows for a quick puncture through the skin on the hip; this process is less popular because of the higher rejection rate due to the jewelry being less optimal than the dermal jewelry. The second procedure, using a scalpel, creates a pocket under your skin for the jewelry to reside; this process has a lower rejection rate. This piercing heals in one to three months, depending on the person’s body; the best way to take care of your piercing is to be careful and do your best in cleaning the area during the healing process. To protect against infection, antibacterial soap is the best way. Make sure to not only clean the pierced area itself, but cleaning your hands before touching the piercing is important.
The most convenient way to wash the piercing is in the shower so the water can run on it, never use a loofah or washcloth as those tend to harbor bacteria. Sea salt is recommended by some, but not others. Contact the person who did your piercing to hear their suggestions based on their choice of jewelry. Things to be avoided during the healing process include pools, the sea, dirty clothes, changing the jewelry for at least three weeks, touching the area with dirty hands; the biggest risk that comes with a hip piercing is piercing migration. This is a result of your body pushing it out. Rejection rates vary depending on the person’s skin, the activities a person partakes in that may create tension in that area, the jewelry or procedure used. Sitting down for a consultation with a professional piercer is recommended before this type of piercing. Another risk includes tissue damage, the damaging of blood vessels or nerves in the dermis or dermal layer; this is more to happen when the piercing is done by someone, not a professional.
If the piercing is too deep, the skin layers may pull together. Shallow piercings will result in rejection; the last risk is bacterial infection, which occurs when the equipment used is not sterilized, or the piercing is not well cared for during the healing process. Pus and inflammation may develop if the piercing becomes infected, careful cleaning and aftercare can avoid this risk. Hip piercings are considered contemporary in origin. Hips piercing done freehanded Hips piercing done with a clamp
