Mimicry
In evolutionary biology, mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry functions to protect a species from predators, making it an anti-predator adaptation. Mimicry evolves if a receiver (such as a predator) perceives the similarity between a mimic (the organism that has a resemblance) and a model (the organism it resembles) and as a result changes its behaviour in a way that provides a selective advantage to the mimic. The resemblances that evolve in mimicry can be visual, acoustic, chemical, tactile, or electric, or combinations of these sensory modalities. Mimicry may be to the advantage of both organisms that share a resemblance, in which case it is a form of mutualism; or mimicry can be to the detriment of one, making it parasitic or competitive. The evolutionary convergence between groups is driven by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taiwan
Taiwan, officially the Republic of China (ROC), is a country in East Asia, at the junction of the East and South China Seas in the northwestern Pacific Ocean, with the People's Republic of China (PRC) to the northwest, Japan to the northeast, and the Philippines to the south.

Senkaku Islands
The are a group of uninhabited islands in the East China Sea, administered by Japan. They are located northeast of Taiwan, east of China, west of Okinawa Island, and north of the southwestern end of the Ryukyu Islands. They are known in mainland China as the Diaoyu Islands or Diaoyu Dao and its affiliated islands (; also simply ), in Taiwan as the Diaoyutai Islands or Tiaoyutai Islands (), and sometimes in the Western world by the historical name Pinnacle Islands. cites Hagstrom 2005; "The islands are also called 'Pinnacle Islands' for convenience and neutrality sake by Western scholars" In Okinawan they are called . In the Yaeyama language, they are called ''iigunkubajima''. The islands are the focus of a territorial dispute between Japan and China and between Japan and Taiwan. China claims the discovery and ownership of the islands from the 14th century, while Japan maintained ownership of the islands from 1895 until its surrender at the end of World War II. The United ...

Hypselodoris Apolegma
''Hypselodoris apolegma'' is a species of colourful sea slug or dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae. Taxonomic history Recent phylogenetic data confirm the validity of the species and suggest a sister species relationship between ''Hypselodoris apolegma'' and '' Hypselodoris bullockii''.Johnson R.F. & Gosliner T.M. (2012) ''Traditional taxonomic groupings mask evolutionary history: A molecular phylogeny and new classification of the chromodorid nudibranchs.'' PLoS ONE 7(4): e33479 A later study revealed a large clade of animals with similar colouration with ''Hypselodoris brycei'' as sister species to ''H. apolegma''.Epstein, H. E.; Hallas, J.

Hypselodoris Iba
''Hypselodoris iba'' is a species of sea slug or dorid nudibranch, a marine (ocean), marine gastropod mollusc in the family (biology), family Chromodorididae. It has previously been confused with ''Hypselodoris bullocki''. Distribution This nudibranch was described from depth at Aphol’s Reef, Tingloy, Maricaban Island, Batangas, Philippines, . It is also reported from Indonesia. Description ''Hypselodoris iba'' has previously been confused with ''Hypselodoris bullocki'' although DNA sequencing suggests that it is a mimic rather than a close relative. It has a range of colour forms. Typically it has a violet semi-translucent body with a bright opaque white margin to the mantle. The violet colouration can be absent and replaced by milky white or present just as a more intense inner border to the mantle. In these pale colour forms there is usually a brown patch in the middle of the back, edged with violet. The gills are pale at the base becoming orange or brown towards the tips ...
