However, it is likely there are many other species that have not been described. Brusca and Brusca, 2003 Scheltema, 2001 Geographic Range Aplacophorans are found throughout the oceans over the world. Barnes, 1987 Biogeographic Regions: arctic ocean ; indian ocean; atlantic ocean pacific ocean ; mediterranean sea. Habitat Exclusively marine, aplacophorans mainly burrow into the substrate in water more than 20 m deep, and may reach densities up to 4-5 per square meter. Aplacophorans in the sub-class Chaetodermomorpha are limited by a minimum salinity of 28-30%. Jones and Baxter, 1987 These animals are found in the following types of habitat: saltwater or marine Aquatic Biomes: benthic Systematic and Taxonomic History Once classified with holothurian echinoderms, aplacophorans were recognized as mollusks in 1875. Although chitons and aplacophorans have been put into separate groups, they may form a monophyletic clade, referred to as Aculifera (or Amphineura).

Species Name: Megabalanmus coccopoma Darwin,1854 Common Name(s): Titan Acorn Barnacle Synonymy: Studies are ongoing to determine if Megabalanmus coccopoma and the Asian-Pacific species M. rosa are the same species (Powers et al. 2006). If so, the native range and introduced distribution of the species will need to be reassessed. Species Description: The titan acorn barnacle Megabalanmus coccopoma , is not native to the Atlantic but now occurs along the U.S. Atlantic coast and in the Gulf of Mexico. It is a very large balanid (acorn barnacle family), pink in color and growing to over 5 cm in height and width (Kerckhof 2002, Jaxshells Potentially Misidentified Species: A number of non-native balanid barnacles occur in Florida and have introduced ranges that potentially overlap that of Megabalanmus coccopoma . The Mediterranean barnacle Megabalanus antillensis Balanus tintinnabulum ) and the Pacific barnacle Balanus trigonus are two such species that are similar in color to

Synonymy: Darwin originally described 9 morphologically distinct Balanus amphitrite subspecies , but numerous subsequent revisions including genetic alalysis by Flowerdew (1985) currently recognize only a single subspecies worldwide. Species Description: The striped barnacle, Balanus amphitrite , is a medium-sized surface-fouling, sessile barnacle with distinct vertical bands of purple stripes on it's protective rigid housing plates, known as capitulum plates. It is conical in appearance and largest at the base, with a diamond-shaped opening protected by a movable opercular lid composed of two symmetrical triangular halves. Each of these halves contains two plates, the tergum and the scutum. The operculum opens when is the lid halves are flexed out to the sides (Cohen 2005). B. amphitrite

The body is smooth and cylindrical (Eldredge and Smith 2001). A number of distinct morphs of this species, based on body color and stripe pattern were identified several decades ago, although these may actually represent points along a gradient in appearance (Uchida 1932, Shick and Lamb 1977).

Color is variable, ranging from light gray to brown to almost black, commonly with irregular patches or mottled patterns, spots, chevrons and a series of light-colored lines. The tail is somewhat laterally compressed. A prominent identifying feature of this species is the extensible dewlap or throat fan which can be yellow to red-orange in color and is used in territorial and mating displays.

Species Description: The green iguana, Iguana iguana is a popular pet trade species not native to Florida, but increasingly encountered as an escaped exotic in the southern half of the state. I. iguana is variable in color, young animals being bright green and then becoming more uniform grayish green in color with age. Green iguanas also have a limited ability to alter color based on mood or social interaction or in response to environmental conditions, with males exhibiting more color variation than females (Frye 1995). Potentially Misidentified Species: Although a growing assortment of exotic iguanids, polychrotids (anoles), geckonids (geckos), and other non-native lizards are now encountered in Florida, relatively few of these could be easily misidentified as

Public Domain illustration by Wilhelm von Wright. Sturnus vulgaris juvenile. Photographer R. Wampers. Species Name: Sturnus vulgaris , L. Common Name: European Starling, Blackbird, Common Starling, English Starling Species Description: The European starling ( Sturnus vulgaris ) is a small bird native to Europe but now widely distributed throughout the U.S. In both males and females, the nape, breast and back are covered in iridescent green glossed feathers while the wings are black, sometimes with a sheen that is green or purple in color. The breast may become flecked with white during the winter months. The legs are reddish brown and the irises are dark brown, and the bill is yellow during mating season and black for the remainder of the year (Weber 1979, Craig and Feare 1999, Chow 2000). Some sexual dimorphism exists. Males have elongate breast feathers and a bluish spot at the base of the beak whereas females have short breast plumage and a reddish pink speck at the base of the beak. Juveniles have more rounded wing tips and brownish-black bills (Weber 1979, Craig and Feare 1999).

Ancient Rome: Animation: The water organ of Vitruvius Animation: Vitruvs Wasserorgel Don't see animation? Install the shockwave Plugin According to Vitruvius, Ktesibios was the first to build an organ like this. The water organ of Vitruvius is an enhanced verion, which uses two cylinders. Organs were used especially in the late Classical Antiquity. We are not quite sure wheter the Romans used Vitruvius' notes, or notes of other mechanics. The two plungers are moved up and down. If you move a plunger down, air (red) flows through a valve. If you move it up, the valve closes and the air is piped to the hemisphere. This hemisphere is placed in a reservoir, filled with water. The air is partially compressed, and partially the water is pressed down the hemisphere by the air. The water line in the reservoir rises. One part of the air floats thorugh a pipe on the top of the hemisphere. There the air floats, passing another valve, in a chamber, whis is connected to the pipes. If a key is pressed, a valve opens. Air floats through a pipe, a tone is created. The interesting part about this organ is, that water keeps an instant pressure. If air floats out of a pipe, the pressure in the reservoir decreases. The water line sinks and the pressure is restorred to normal.
