Pourtalesia Vinogradovae
''Pourtalesia'' is a genus of the family Pourtalesiidae which belongs to the irregular (bilaterally symmetrical) sea urchins. The animals measure 5–6 cm in length and live in the abyssal zone of the Atlantic, Pacific, Indopacific and Antarctic Oceans where they have been found in more than 3,000 m depth. The mouth opening of these animals is located anteriorly and the lantern of Aristotle is missing as typically for holasteroid sea urchins.

Pourtalesia Miranda
''Pourtalesia miranda'', commonly known as the wonderful sea urchin, is a species of sea urchin in the family Pourtalesiidae. It is found at abyssal depths in the Atlantic Ocean. Description The thin-shelled test is bottle-shaped, more than twice as long as it is wide, and with a marked rostrum at the posterior end. At the anterior end, the aboral ambulacrum is sunk, forming a funnel-like, forward-facing, nearly circular opening that leads to the peristome. The aboral surface has scattered low tubercles. ''Pourtalesia miranda'' differs from the otherwise similar '' Helgocystis'' in having the posterior ambulacral plate separate from the others. Adults are about long. The post-larval ''Pourtalesia miranda'' is at first radially symmetric, but as it grows, it becomes increasingly bilaterally symmetric. Growth is performed in two ways, by the creation of new plates at the apical end, and by the enlargement of existing plates by accretion around their margins. It is in the combina ...

Charles Wyville Thomson
Sir Charles Wyville Thomson (5 March 1830 – 10 March 1882) was a Scottish natural historian and marine zoologist. He served as the chief scientist on the Challenger expedition; his work there revolutionized oceanography and led to his knighthood. Life Thomson was born at Bonsyde, in Linlithgow, West Lothian, on 5 March 1830, the son of Andrew Thomson, a surgeon in the service of the East India Company, and his wife Sarah Ann Drummond Smith. He was baptised Wyville Thomas Charles Thomson, and changed his name in 1876. He was educated under Charles Chalmers at Merchiston Castle School, then from 1845 studied medicine at the University of Edinburgh graduating with an MD. However, his focus turned from medicine to natural science, and he joined the Botanical Society of Edinburgh in 1847, and soon after became secretary to the Royal Physical Society of Edinburgh. In 1850 he was attending the botany class of John Hutton Balfour at the University. In 1850 he was appointed lecture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
