Siphonaria Normalis
The False 'Opihi or False limpet otherwise known as Siphonaria normalis is an air breathing sea snail that shares its appearance with true limpets. 'Opihi means limpet in Hawaiian. They are part of the Order of Siphonariidae which are known as false limpets. They live in the mid to upper rocky intertidal zone along the coastlines and can be found throughout the Indo-Pacific regions. Description These False limpets have a ribbed shell with a brown and white coloration. They can reach a maximum length of 20mm, but it is usually less than that size in Hawaii. Reproduction They lay egg masses, in a spiral formation. When the eggs hatch, the Siphonaria normalis are then in the juvenile stage of their life. Ecology ''Siphonaria normalis'' or False 'Opihi are grazers that generally consume algae along the rocky intertidal zones. The variety of algae consumed consists of lichens, cyanobacteria, diatoms, microalgae, and foliose macroalgae. As our climate continues to get warmer i ...

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Augustus Addison Gould
Augustus Addison Gould (April 23, 1805 – September 15, 1866) was an American conchologist and malacologist. Biography Born in New Ipswich, New Hampshire, he was the son of music teacher Nathaniel Duren Gould (1781–1864) who was also noted for his penmanship. Physician He graduated from Harvard College in 1825, and took his degree of doctor of medicine in 1830. "Establishing himself in Boston, he devoted himself to the practice of medicine, and finally rose to high professional rank and social position. He became president of the Massachusetts Medical Society, and was employed in editing the vital statistics of the state." In 1848, he was elected as a member of the American Philosophical Society. In 1855 he delivered the annual address at the Massachusetts Medical Society, entitled “Search Out the Secrets of Nature.” He was its president from 1864 until his death. In 1856, he was appointed visiting physician to the Massachusetts General Hospital. Naturalist "As a con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siphonariidae
Siphonariidae, also known as false limpets, are a taxonomic family of small to medium-sized air-breathing sea snails, marine and brackish water pulmonate gastropod molluscs. __TOC__ Shell description Empty siphonariid limpet shells can be distinguished from true limpet shells by examining the interior. In the siphonariids there is a well-marked lateral groove on the right side of the shell, and a corresponding interruption of the ring of muscle attachment scars. These markers show the positioning of the pneumostome or pulmonary The lungs are the primary organs of the respiratory system in humans and most other animals, including some snails and a small number of fish. In mammals and most other vertebrates, two lungs are located near the backbone on either side of ... orifice.
