Sven Ludvig Lovén
Prof Sven Ludvig Lovén (6 January 1809 – 3 September 1895), was a Swedish marine zoologist and malacologist. The Sven Lovén Centre for Marine Sciences within the University of Gothenburg was named in his honour. Life Lovén was born in Stockholm, Sweden. He studied at Uppsala University in 1823, and enrolled at Lund University in 1824. He completed his studies with a Magister degree in 1829. The following year, he was appointed associate professor of zoology at Lund University. During the years 1830–1831, Lovén traveled to Berlin where he studied anatomy and microscopy techniques under the guidance of Christian Gottfried Ehrenberg (1795–1876) and Karl Rudolphi (1771–1832) at Humboldt University of Berlin. He made scientific journeys in the early 1830s along the Swedish west coast. During 1836–1837, he made a trip to Finnmark in northern Norway and to Spitsbergen. In 1840, Lovén was elected a member of the Swedish Royal Academy of Sciences. In 1841, he was a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Urchin
Sea urchins () are spiny, globular echinoderms in the class Echinoidea. About 950 species of sea urchin live on the seabed of every ocean and inhabit every depth zone from the intertidal seashore down to . The spherical, hard shells (tests) of sea urchins are round and spiny, ranging in diameter from . Sea urchins move slowly, crawling with tube feet, and also propel themselves with their spines. Although algae are the primary diet, sea urchins also eat slow-moving (sessile) animals. Predators that eat sea urchins include a wide variety of fish, starfish, crabs, marine mammals. Sea urchins are also used as food especially in Japan. Adult sea urchins have fivefold symmetry, but their pluteus larvae feature bilateral (mirror) symmetry, indicating that the sea urchin belongs to the Bilateria group of animal phyla, which also comprises the chordates and the arthropods, the annelids and the molluscs, and are found in every ocean and in every climate, from the tropics to the pol ...

Spatangoida
The heart urchins or Spatangoida are an order of sea urchins. Their body is a somewhat elongated oval in form, and is distinguished by the mouth being placed towards one end of the animal, and the anus towards the other. As a result, heart urchins, unlike most other sea urchins, are bilaterally symmetrical, and have a distinct anterior surface. The presence and position of the mouth and anus typically give members of this group the distinct "heart" shape from which they get their name. Heart urchins have no feeding lantern, and often have petaloids sunk into grooves. They are a relatively diverse order, with a number of varying species.
