Ring-Tailed Lemur

Saturday, 27 July 2013

The Ring-Tailed Lemur (Lemur catta) is a large strepsirrhine primate and the most recognized lemur due to its long, black and white ringed tail. It belongs to Lemuridae, one of five lemur families, and is the only member of the Lemur genus. Like all lemurs it is endemic to the island of Madagascar. Known locally in Malagasy as maky ([makʲ] ( listen), spelled maki in French) or hira, it inhabits gallery forests to spiny scrub in the southern regions of the island. It is omnivorous and the most terrestrial of lemurs. The animal is diurnal, being active exclusively in daylight hours.

The ring-tailed lemur is highly social, living in groups of up to 30 individuals. It is also female dominant, a trait common among lemurs. To keep warm and reaffirm social bonds, groups will huddle together. The ring-tailed lemur will also sunbathe, sitting upright facing its underside, with its thinner white fur towards the sun. Like other lemurs, this species relies strongly on its sense of smell and marks its territory with scent glands. The males perform a unique scent marking behavior called spur marking and will participate in stink fights by impregnating their tail with their scent and wafting it at opponents.

Black Turban Snail

Wednesday, 3 July 2013

Black Turban Snail: scientific name Tegula funebralis, is a species of medium-sized sea snail with gills and an operculum, a marine gastropod mollusc in the family Turbinidae. This Eastern Pacific Ocean species was previously known as Tegula funebralis. The species is found along the Pacific coast of North America from Vancouver Island to the central part of the Baja California peninsula in Mexico. Most adult individuals of this species have shells which are 20 to 40 mm (or about an inch, to an inch and three quarters) in diameter. 

Empty shells of this species are very often used by hermit crabs, especially Pagurus samuelis. In 1971 a new sense organ was discovered in this marine snail. Chemoreceptor organs were found near the base on the border of the leaflets of the ctenidium (comb-like respiratory gills), one on each leaflet. They form a light swelling near the base of the leaflet with a pocket lying within the swelling. Together they are termed a "bursicle".
