NounSingular species Plural species species (plural species)
From Wiktionary under the GNU Free Documentation License. There are quite a lot of definitions of what kind of unit a species is (or should be). A common definition is that of a group of organisms capable of interbreeding and producing fertile offspring of both genders, and separated from other such groups with which interbreeding does not (normally) happen. Other definitions may focus on similarity of DNA or morphology. Some species are further subdivided into subspecies, and here also there is no close agreement on the criteria to be used. Biologists' working definitionA usable definition of the word "species" and reliable methods of identifying particular species is essential for stating and testing biological theories and for measuring biodiversity. Traditionally, multiple examples of a proposed species must be studied for unifying characters before it can be regarded as a species. It is generally difficult to give precise taxonomic rankings to extinct species known only from fossils. Some biologists may view species as statistical phenomena, as opposed to the traditional idea, with a species seen as a class of organisms. In that case, a species is defined as a separately evolving lineage that forms a single gene pool. Although properties such as DNA-sequences and morphology are used to help separate closely-related lineages, this definition has fuzzy boundaries. However, the exact definition of the term "species" is still controversial, particularly in prokaryotes, and this is called the species problem. Biologists have proposed a range of more precise definitions, but the definition used is a pragmatic choice that depends on the particularities of the species concerned. From Wikipedia under the

Butanding (Whale shark) - These friendly vegetarians known as the largest fishes in the whole world are hunted in the seas of Philippines. Although the law said it's illegal, many fishermen still hunt them for the big money they get for each kilo of butanding meat. DUGONG (Sea cows) - These cute and heavy sea mammals are too slow and too weak to defend themselves from illegal fishermen. It's disappointing that they are being hunted for their delicious meat. pawikan (Philippine green turtle) - They are steamed, collected, and sold in black markets. These hard-shelled reptiles are fastly decreasing in number. Poor lads. PATING (Sharks) - They are hunted - not because they are fierce sea predators - but because of their fins. Yes. Fins.… [cont.] Answered by gonzo - Thu May 31 21:32:20 2007 What are the species that can reproduce by themselves without the help of another gender? Q. How many species of these creatures are there and what are these species? Are they called asexual? I need a lot of info, any recommended sites too! Asked by Amanda L - Thu Mar 27 18:10:33 2008 - - 7 Answers - 0 Comments A. Anything that reproduces by itself without need for another of the same species is called asexual. This means they reproduce by a process called mitosis, where the result is two absolutely genetically identical 'animals'. There are loads of different creatures that can reproduce like this, and example being bacteria. Some animals, like yeast, can reproduce both asexually and sexually depending on the conditions they're in. Yeast reproduce asexually (a process called 'budding') when they are in an environment with no oxygen, and reproduce sexually when there is oxygen. Plants can also reproduce asexually, for example strawberry plants can! If you need more information, a good site for just asexual animal reproduction is (it's nice and… [cont.] Answered by floro13 - Thu Mar 27 18:21:19 2008 What role does the government play in adding species to the Endangered Species List?
Q. Basically, i'm trying to figure out if they have a role at all. I know that sites have said things like, under the Bush administration, 59 species have been added to the list. But what do they do specifically? Does the government decide which species get on the list? I have no idea, and it's bothering me. Asked by Ashley C - Thu Jan 29 21:24:58 2009 - - 3 Answers - 0 Comments A. Well, as an example there may be a species of bird that lives in a particular area only. It may have a long gestation period and mate for life. There may also be uranium in the ground under the trees they inhabit. If the government grants a mining lease for the area - the birds will most likely die out. There's loads of examples - but you get the drift.
