Pumicestone Channel
Pumicestone Channel, also known as the Pumicestone Passage, is a narrow waterway between Bribie Island and the mainland in Queensland, Australia. The northern extent of the passage is at Caloundra, while at the south is Deception Bay. The waterway is a two way tidal estuary that has 11 creeks flowing into it. At each end of the passage the channels are the deepest and widest. During periods of unusually high tides and large waves, the passage is infiltrated by inflows through channels in dunes at the northern tip of Bribie Island. History The channel was originally shown as Pumice-stone River on the maps of Matthew Flinders as he found an abundance of pumice stone lining the shoreline. He was the first European explorer to enter Moreton Bay in 1799 on the Sloop H. M. 'Norfolk' and spent two weeks exploring the bay and surrounds and naming Point Skirmish and Pumice-stone River. Environment Gazetted in 1986, Pumicestone Passage Marine Park (now part of the Moreton Bay ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dugongs
The dugong (; ''Dugong dugon'') is a marine mammal. It is one of four living species of the order Sirenia, which also includes three species of manatees. It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (''Hydrodamalis gigas''), was hunted to extinction in the 18th century. The dugong is the only sirenian in its range, which spans the waters of some 40 countries and territories throughout the Indo-West Pacific. The dugong is largely dependent on seagrass communities for subsistence and is thus restricted to the coastal habitats which support seagrass meadows, with the largest dugong concentrations typically occurring in wide, shallow, protected areas such as bays, mangrove channels, the waters of large inshore islands and inter-reefal waters. The northern waters of Australia between Shark Bay and Moreton Bay are believed to be the dugong's contemporary stronghold. Like all modern sirenians, the dugong h ...
