1 Spotted mangrove
seedling 3 G. ... Availability of freshwater and duration of daily tidal changes affect soil conditions which then limit the distribution of species within a mangrove community. ... For the roots to be able to ¡®breathe¡¯ during times of tidal drying, aerial roots known as pneumatophores aerate those parts of mangrove which are deprived of an adequate oxygen supply. ...
Pneumatophores are short, erect, spongy, fingerlike roots which extend from the main roots of the mangrove and grown 10-20cm above the surface. ...
In red mangrove (Rhizophora stylosa), long, stout, arching prop roots which grown outwards from the trunk and have lenticls along them which help with oxygen exchange. In the river mangrove, the surface roots, which are arranged in a radial pattern, are thought to take up oxygen when exposed at low tide. ...
The formation of the seedlings on the mangrove itself was a clever adaption to ensure maximum survival of the seedlings. ... Propagules may consist of only the seedling (red and yellow mangrove), or the whole fruit (orange and grey mangrove). ...
Grazing
The Hercules mud welk feeds on plant materials and algae on the mangrove leaves.
The snail attaches onto the mangrove leaves and graze on algae. ... Commensalisms
Oyster gains the benefits as it takes refuge in the exposed roots of a mangrove. ...

Avicennia marina (grey mangrove) belongs to the family Avicenniaceae and is found very commonly around the coasts of Australia. It also can be found as far south as South Australia and Victoria where it is the only mangrove species able to withstand the cooler climate. ...
Description
The size of the mangrove is determined on where it is growing, this mangrove may range from less that half a metre to over 25 metres high. ...
The leaves are oval in shape and are arranged opposite eachother on the stem of the mangrove. ... The flowers of the grey mangrove are small, yellow and appear in clusters. ... The gray mangrove has pale green, flattened fruits, which measure 3cm long and 2cm wide and consist of a thin hairy seed coat enclosing two closely folded seed leaves.
Salt tolerance
The grey mangrove is very tolerant of its envrionment and adapt to sites that are temporary flooding by freshwater or a salinity exceeding that of seawater. The grey mangrove is able to survives in a saline environment by resisting the uptake of salt at the roots.
Economic importance
Australian aborigines used this mangrove for shields because of its light weight and strength. European settlers also used this mangrove as a material for building boats, and the leaves were used as a cattle fodder.
This mangrove brings many advantages to the marine community sych has a shelter for oyster settlements, an abundant source of pollen for bee keepers and provides suitable habitats for waterbirds and a breeding ground and a shelter for many kinds of fish and other ornagisms. ...

The red mangrove (Rhizophora stylosa) belongs to the family Rhizophoraceae and is commonly found across coastal Northern Australia from the Richmond River in New South Wales to Shark Bay in Western Australia.
Red mangrove forms zones, around the shores of shallow protected bays, estuaries and inlets where it prefers soft, well drained muddy soils.
The red mangrove is the prevailing species of the lower tidal mangrove forest, and is commonly seen growing along the lower tidal reaches of rivers and very close to the seaward fringe of mangroves.
