Leucosolenia Botryoides
The orange pipe sponge, sometimes referred to as the orange pipe calcerous sponge or ''Leucosolenia botryoides'', is a soft, white sponge with a tubular branching structure. The name is derived from the Greek word, "botrys", which means "cluster of grapes", relating to the branched structure of the sponge. It was originally found and named ''Spongia botryoides'' and given the common name "grape sponge" by researchers John Ellis and Daniel Charles Solander in 1786 before it was discovered to be a part of the genus ''Leucosolenia'' and changed to the orange pipe sponge. In Ellis and Solander's discovery, they described the sponge as "tender and branched as in bunches" where the "bunches are hollow." It is considered an asconoid sponge because it has no definitive shape. Distribution ''Leucosolenia botryoides'' is found within the North Atlantic Ocean, more commonly on the coasts of Britain and Ireland. It also can be found from the North of Norway to the Mediterranean Coast. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daniel Solander
Daniel Carlsson Solander or Daniel Charles Solander (19 February 1733 – 13 May 1782) was a Swedish naturalist and an apostle of Carl Linnaeus. Solander was the first university-educated scientist to set foot on Australian soil. Biography Solander was born in Piteå, Norrbotten, Sweden, to Rev. Carl Solander a Lutheran principal, and Magdalena (née Bostadia). Solander enrolled at Uppsala University in July 1750 and initially studied languages, the humanities and law. The professor of botany was the celebrated Carl Linnaeus, who was soon impressed by young Solander's ability and accordingly persuaded his father to let him study natural history. Solander travelled to England in June 1760 to promote the new Linnean system of classification. In February 1763, he began cataloguing the natural history collections of the British Museum, and was elected a Fellow of the Royal Society in June the following year. In 1768, Solander gained leave of absence from the British Museum and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Calcareous Sponge
The calcareous sponges of class Calcarea are members of the animal phylum Porifera, the cellular sponges. They are characterized by spicules made of calcium carbonate in the form of calcite or aragonite. While the spicules in most species have three points, in some species they have either two or four points. Biology All sponges in this class are strictly marine, and, while they are distributed worldwide, most are found in shallow tropical waters. Like nearly all other sponges, they are sedentary filter feeders. All three sponge body plans are represented within class Calcarea : asconoid, syconoid, and leuconoid. Typically, calcareous sponges are small, measuring less than in height, and drab in colour. However, a few brightly coloured species are also known. Calcareous sponges vary from radially symmetrical vase-shaped body types to colonies made up of a meshwork of thin tubes, or irregular massive forms. The skeleton has either a mesh or honeycomb structure. Classifica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osculum
The osculum (plural "oscula") is an excretory structure in the living sponge, a large opening to the outside through which the current of water exits after passing through the spongocoel. Wastes diffuse into the water and the water is pumped through the osculum carrying away with it the sponge's wastes. Sponges pump large volumes of water: typically a volume of water equal to the sponge's body size is pumped every five seconds. The size of the osculum is regulated by contractile myocytes. Its size, in turn, is one of the factors which determines the amount of water flowing through the sponge Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through t .... It can be closed completely in response to excess silt in the water.

Protogynous Hermaphrodite
Sequential hermaphroditism (called dichogamy in botany) is a type of hermaphroditism that occurs in many fish, gastropods, and plants. Sequential hermaphroditism occurs when the individual changes its sex at some point in its life. In particular, a sequential hermaphrodite produces eggs (female gametes) and sperm (male gametes) at different stages in life. Species that can undergo these changes from one sex to another do so as a normal event within their reproductive cycle that is usually cued by either social structure or the achievement of a certain age or size. In animals, the different types of change are male to female (protandry or protandrous hermaphroditism), female to male (protogyny or protogynous hermaphroditism), bidirectional (serial or bidirectional hermaphroditism). Both protogynous and protandrous hermaphroditism allow the organism to switch between functional male and functional female. Bidirectional hermaphrodites have the capacity for sex change in either directi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
