Siganus Spinus
''Siganus spinus'', the little spinefoot, scribbled rabbitfish, blunt-nosed spinefoot, spiny rabbitfish, or spiny spinefoot, is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It is found in the Indo-Pacific region. Taxonomy ''Siganus spinus'' was first formally described in 1758 as ''Sparus spinus'' by Carl Linnaeus in the 10th edition of the ''Systema Naturae'' with the type locality given as Java. The specific name ''spinis'' means "thorn" or "spine" which. as the only spine Linnaeus mentioned in his description was the forward pointing in front of the dorsal fin, is presumably a reference to that spine, however, it could also be a reference to the robust and venom-bearing spines on the dorsal, anal and pelvic fins. Description ''Siganus spinus'' has a laterally compressed, deep and relatively slender body which has a depth which fits into its standard length 2.3 to 2.8 times. The dorsal profile of the head is indented above eye, the snout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anal 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 pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moreton Bay
Moreton Bay is a bay located on the eastern coast of Australia from central Brisbane, Queensland. It is one of Queensland's most important coastal resources. The waters of Moreton Bay are a popular destination for recreational anglers and are used by commercial operators who provide seafood to market. The Port of Brisbane coordinates large traffic along the shipping channel which crosses the northern section of the bay. The bay serves as a safe approach to the airport and reduces noise pollution over the city to the west of the runway. A number of barge, ferry and water-taxi services also travel over the bay. Moreton Bay was the site of conflict between the Quandamooka people and early European settlers. It contains environmentally significant habitats and large areas of sandbanks. The bay is the only place in Australia where dugong gather into herds. Many parts of the mainland foreshore and southern islands are settled. The waters of Moreton Bay are relatively calm, bein ...

Hyaline
A hyaline substance is one with a glassy appearance. The word is derived from , and . Histopathology Hyaline cartilage is named after its glassy appearance on fresh gross pathology. On light microscopy of H&E stained slides, the extracellular matrix of hyaline cartilage looks homogeneously pink, and the term "hyaline" is used to describe similarly homogeneously pink material besides the cartilage. Hyaline material is usually acellular and proteinaceous. For example, arterial hyaline is seen in aging, high blood pressure, diabetes mellitus and in association with some drugs (e.g. calcineurin inhibitors). It is bright pink with PAS staining. Ichthyology and entomology In ichthyology and entomology Entomology (from Ancient Greek ἔντομον (''éntomon''), meaning "insect", and -logy from λόγος (''lógos''), meaning "study") is the branch of zoology that focuses on insects.
