Rasbora Vulgaris
''Rasbora vulgaris'', the blacktip rasbora, is a species of ray-finned fish in the genus ''Rasbora''. It is a member of the ''R. paviana''-subgroup, which comprises five species from Indochina and the Malay Peninsula ('' R. paviana, R. vulgaris, R. notura, R. hobelmani'', and ''R. dorsinotata'') Description A maximum body length of 7.8 cm. However, there are unconfirmed reports of larger wild specimens up to 10 cm. A slender-bodied species with females being much broader, with a base color of a brownish green to bluish white. The identifying feature of the species from others of its group is the lack of a black line covering the lateral line, a singular diamond black blotch at the base o the caudle peduncle, and a faded black marking near the end of each lobe of the caudal fin, near similar to the tail of ''R. trilineata''. Distribution It is found and is possibly endemic to the western coast of Peninsular Malaysia Peninsular Malaysia, historically known as ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Rasbora
''Rasbora'' is a genus of fish in the family Danionidae. They are native to freshwater habitats in South and Southeast Asia, as well as southeast China. A single species, ''R. gerlachi'', is only known from an old specimen that reputedly originated from Africa (Cameroon), but this locality is considered doubtful. They are small, up to long, although most species do not surpass and many have a dark horizontal stripe. Several species are regularly kept in aquariums. As a common English name, "rasbora" is used for many species in the genus ''Rasbora'', as well as several species in genera '' Brevibora'', '' Boraras'', ''Megarasbora'', '' Metzia'', '' Microdevario'', '' Microrasbora'', '' Rasboroides'', ''Rasbosoma'', '' Sawbwa'', '' Trigonopoma'' and '' Trigonostigma''.Marelius, Charlotte (January 2014)Rasboras—Where do they come from?Showfish, Newsletter of COAST, a Tropical Fish Club in Southern California January 2014.

Lateral Line
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical impulses via excitatory synapses. Lateral lines play an important role in schooling behavior, predation, and orientation. Early in the evolution of fish, some of the sensory organs of the lateral line were modified to function as the electroreceptors called ampullae of Lorenzini. The lateral line system is ancient and basal to the vertebrate clade, as it is found in fishes that diverged over 400 million years ago. Function The lateral line system allows the detection of movement, vibration, and pressure gradients in the water surrounding an animal. It plays an essential role in orientation, predation, and fish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish ( Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish ( Chondrichthyes) and jawless fish ( Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peninsular Malaysia
Peninsular Malaysia, historically known as Malaya and also known as West Malaysia or the Malaysian Peninsula, is the western part of Malaysia that comprises the southern part of the Malay Peninsula on Mainland Southeast Asia and the list of islands of Malaysia, nearby islands. Its area totals approximately , which is nearly 40% of the total area of the country; the other 60% is in East Malaysia on the island of Borneo. It shares a land border with Thailand to the north and a maritime border with Singapore to the south. Across the Strait of Malacca to the west lies the island of Sumatra, and across the South China Sea to the east lie the Natuna Islands of Indonesia. At its southern tip, across the Strait of Johor, lies the island country of Singapore. Most of Peninsular Malaysia's interior is forested, mountainous and rural; the majority of Malaysia's population and economy are concentrated on the coastal western half, which is where the country's prominent urban areas are located ...

Fish Of Thailand
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...
