Spirobranchus Corniculatus
''Spirobranchus corniculatus'', commonly referred to as the Indo-Pacific Christmas tree worm, is a species of tube-building annelid fanworms in the family Serpulidae. Belonging to the class Polychaeta, it is recognized for its bristle-like tentacles and the presence of a structure called radioles. It is widely encountered and recognized for its unique resemblance to a conifer and its diverse array of colors. Initially presumed to be part of a species group including '' Spirobranchus cruciger'' and '' Spirobranchus gaymardi'', it has been determined to be a singular, morphologically adaptable species inhabiting the Central Indo-Pacific region. Description The Christmas tree worm is very vibrant in color and changes its color based on depth, camouflage, and a scare tactic. It has bright spiral rings around its body segments or radioles, which can number more than 200 segments. The body is abnormally large, ranging up to long and wide. Biology The species predominantly engage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surat Thani Province
Surat Thani (, ), often shortened to Surat, is the largest of the southern provinces (''changwat'') of Thailand. It lies on the western shore of the Gulf of Thailand. Surat Thani means 'city of good people', a title given to the city by King Vajiravudh (Rama VI); Surat Thani is therefore the sole province in Southern Thailand for which the native name is in the Central Thai language. Geography Surat Thani Province, located in Thailand, is bordered by the provinces of Chumphon to the north, Nakhon Si Thammarat to the east, Krabi to the south, Phang Nga to the southwest, and Ranong to the northwest. The geographic landscape of Surat Thani is diverse. The central region of the province is dominated by the coastal plain of the Tapi River, characterized by a mix of grassland, rubber trees, palm oil trees, and coconut plantations. To the west lie the limestone mountains of the Phuket range, largely enveloped in forest, home to the renowned Khao Sok National Park. The easter ...

Serpulidae
The Serpulidae are a family of sessile, tube-building annelid worms in the class Polychaeta. The members of this family differ from other sabellid tube worms in that they have a specialized operculum that blocks the entrance of their tubes when they withdraw into the tubes. In addition, serpulids secrete tubes of calcium carbonate. Serpulids are the most important biomineralizers among annelids. About 300 species in the family Serpulidae are known, all but one of which live in saline waters. The earliest serpulids are known from the Permian ( Wordian to late Permian), and possibly the upper Permian south China The blood of most species of serpulid and sabellid worms contains the oxygen-binding pigment chlorocruorin. This is used to transport oxygen to the tissues. It has an affinity for carbon monoxide which is 570 times as strong as that of the haemoglobin found in human blood. Empty serpulid shells can sometimes be confused with the shells of a family of marine gastropo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Porites Lobata
''Porites lobata'', known by the common name lobe coral, is a species of stony coral in the family Poritidae. It is found growing on coral reefs in tropical parts of the Indian and Pacific Oceans. Description ''Porites lobata'' is a hermatypic or reef-building coral. It varies greatly in size and shape depending on its environment. On wave-exposed reef slopes it is encrusting whereas in calm water areas it can grow into large helmet-shaped or hemispherical hummocks up to high and wide. Growth rates are very slow, sometimes being as little as per year, and this means that large corals are very old. The general colour is greenish, yellow or tan because of the zooxanthellae, single-celled microalgae, that live symbiotically within the tissues. These make organic nutrients available to the polyps through photosynthesis. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animals Described In 1862
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia (). With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million living animal species have been described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology, and the study of animal behaviour is known as ethology. The animal kingdom is divided into five major clades, namely Porifera, Ctenophora, Placozoa, Cni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annelids Of The Pacific Ocean
The annelids (), also known as the segmented worms, are animals that comprise the phylum Annelida (; ). The phylum contains over 22,000 extant species, including ragworms, earthworms, and leeches. The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments. The annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species. Cladistic research since 1997 has radically changed this scheme, viewing leeches as a sub-group of oligochaetes and oligochaetes as a sub-group of polychaetes. In addition, the Pogonophora, Echiura and Sipuncula, previously regarded as separate phyla, are now regarded as sub-groups of poly ...
