The fiddler crab plays an important role as prey for many creatures. When disturbed, they run for their burrows, which can be identified by the marble sized pellets of mud that they pile up at the entrance after excavating. In this respect, fiddler crabs on the mud flats act in the same way as worms on land, for as they burrow, they constantly turn over the soil like gardeners. They flower during the warmer months, beginning about March through August. Green briers begin life as seeds in bird and mammal droppings.
Seeds germinate and grow even in deep shade.
The tough vines may grow over the ground and shrubs or climb tree trunks and branches. Green briers can live for many years, building up massive potato-like root systems. Myrsine is a drought-resistant and even able to fare well in a freeze. Female and male flowers appear in small, short-stemmed clusters on separate plants. This wren prefers moist areas and, with its long slender bill, feeds mainly on insects.
