Thalassina
''Thalassina'' is a genus of mud lobsters found in the mangrove swamps of the Indian Ocean and western Pacific Ocean. Its nocturnal burrowing is important for the recycling of nutrients in the mangrove ecosystem, although it is sometimes considered a pest of fish and prawn farms. Description ''Thalassina'' is a lobster-like animal which grows up to long, but is more typically long. Its colour ranges from pale to dark brown and brownish green. The carapace is tall and ovoid, extends over less than one third of the animal's length, and projects forward into a short rostrum. The tail is long and thin, and, like many burrowing decapods, the uropods are reduced in form, and do not form a functional tail fan with the telson. Various rows of setae on the legs and gills are used to prevent sediment from reaching the gills and for expelling any which does reach them. ''Thalassina'' also makes use of "respiratory reversal" to keep the gills free of dirt. Distribution ''Thalassina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Western Australian Museum
The Western Australian Museum is a statutory authority within the Culture and the Arts Portfolio, established under the ''Museum Act 1969''. The museum has six main sites. The state museum, now known as WA Museum Boola Bardip, officially re-opened on 21 November 2020 in the Perth Cultural Centre. The other sites are: the WA Maritime Museum and WA Shipwrecks Museum in Fremantle, the Museum of the Great Southern in Albany, the Museum of Geraldton in Geraldton, and the Museum of the Goldfields in Kalgoorlie-Boulder. History Established in 1891 in the Old Perth Gaol, it was known as the Geological Museum and consisted of geological collections. In 1892, ethnological and biological exhibits were added, and in 1897, the museum officially became the Western Australian Museum and Art Gallery. The museum employed collectors to obtain series of specimens; Tunney ventured across the state from 1895 to 1909 obtaining animals and, later, the tools and artefacts of the indigenous inhabi ...

Gill
A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (pl. branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill cham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
