Notarchus Pleii
''Notarchus'' is a genus of sea slugs or sea hares, marine opisthobranch gastropod mollusks in the family Aplysiidae, the sea hares.Bouchet, P. (2012). Notarchus Cuvier, 1817. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=204962 on 11 June 2012 Description The parapodia (fleshy winglike outgrowths) of ''Notarchus'' are almost completely fused, forming the parapodial cavity. Life habits These sea hares are able to swim by jet propulsion, through sucking in water through the small anterior opening of the parapodial cavity and then squirting water from the back of it. While doing so, they tumble and make a series of backward somersaults. In this unusual manner, they move quickly out of harm's way over short distances. Species Species within the genus ''Notarchus'' include: *''Notarchus indicus'' Schweigger, 1820 : Indian sea hare **Distribution : in shallow waters of NW Indian Ocean, NW Pacific, Mediterranean. **Descr ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' ( Atlantic) before the Pacific was surmised. Conversely, Chinese explorers in the Indian Ocean during the 15th century called it the Western Oceans. In Anci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elysia Timida
''Elysia timida'' is a species of sacoglossan sea slug, a marine opisthobranch gastropod mollusk. Found in the Mediterranean and nearby parts of the Atlantic, it is herbivorous, feeding on various algae in shallow water. Description ''Elysia timida'' is a small sea slug, growing to a length of about . The head bears a pair of long, smooth rhinophores, at the base of which are a pair of black eyespots. The broad foot widens into two lobed parapodia which can fold up over the back. The colour is mainly white with widely scattered red or orange spots, but the dorsal surface of the body, and the inner surface of the parapodia, are some shade of mid- to dark green. When the animal has been living in a habitat with ''Lithophyllum'' or other pink calcareous algae, the white colour may be tinged with mauve. Distribution This marine species used to be considered endemic to the Mediterranean Sea, but has also been found in the Atlantic Ocean, off the Cape Verde and Canary Islands, and ...

Penile Spines
Many mammalian species have developed keratinized penile spines along the glans and/or shaft, which may be involved in sexual selection. These spines have been described as being simple, single-pointed structures (macaques) or complex with two or three points per spine ( strepsirrhines). Penile spine morphology may be related to mating system. Non-human mammals Felines, especially domestic cats, are well known for having penile spines. Upon withdrawal of a cat's penis, the spines rake the walls of the female's vagina, which may serve as a trigger for ovulation. Many other felid species have penile spines, but they are relatively small in jaguars and pumas, and do not occur in margays. Penile spines in chimpanzees and mice are small surface projections made by the piling up of keratinized cell layers in the outermost skin surface.Hill, W.C.O.

Indochina
Mainland Southeast Asia, also known as the Indochinese Peninsula or Indochina, is the continental portion of Southeast Asia. It lies east of the Indian subcontinent and south of Mainland China and is bordered by the Indian Ocean to the west and the Pacific Ocean to the east. It includes the countries of Cambodia, Laos, Myanmar, Thailand and Vietnam, with peninsular Malaysia sometimes also being included. The term Indochina (originally Indo-China) was coined in the early nineteenth century, emphasizing the historical cultural influence of culture of India, Indian and Chinese culture, Chinese civilizations on the area. The term was later adopted as the name of the colony of French Indochina (today's Cambodia, Laos, and Vietnam). Today, the term, Mainland Southeast Asia, in contrast to Maritime Southeast Asia, is more commonly referenced. Terminology The origins of the name Indo-China are usually attributed jointly to the Danish-French geographer Conrad Malte-Brun, who referred ...

Japan
Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia. It is situated in the northwest Pacific Ocean, and is bordered on the west by the Sea of Japan, while extending from the Sea of Okhotsk in the north toward the East China Sea, Philippine Sea, and Taiwan in the south. Japan is a part of the Ring of Fire, and spans an archipelago of 6852 islands covering ; the five main islands are Hokkaido, Honshu (the "mainland"), Shikoku, Kyushu, and Okinawa. Tokyo is the nation's capital and largest city, followed by Yokohama, Osaka, Nagoya, Sapporo, Fukuoka, Kobe, and Kyoto. Japan is the eleventh most populous country in the world, as well as one of the most densely populated and urbanized. About three-fourths of the country's terrain is mountainous, concentrating its population of 123.2 million on narrow coastal plains. Japan is divided into 47 administrative prefectures and eight traditional regions. The Greater Tokyo Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caulerpa
''Caulerpa'' is a genus of seaweeds in the family Caulerpaceae (among the green algae). They are unusual because they consist of only one cell with many nuclei, making them among the biggest single cells in the world. A species in the Mediterranean can have a stolon more than long, with up to 200 fronds. This species can be invasive from time to time. Referring to the crawling habit of its thallus, the name means 'stem (that) creeps', from the Ancient Greek ' (, ‘stalk’) and ' (, ‘to creep’). Taxonomy and nomenclature First described by Jean Vincent Lamouroux in 1809, ''Caulerpa'' is the only genus under the family Caulerpaceae, from the order Bryopsidales, class Ulvophyceae, and phylum Chlorophyta. Through the use of ''tuf''A gene sequencing, it was revealed that ''Pseudochlorodesmis'' F. Børgesen was a sister clade of ''Caulerpa''. Cremen et al. proposed a new classification scheme in Bryopsidales, wherein Caulerpaceae and Halimedaceae were described as sister f ...

Mediterranean
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.
