The tropical mangrove ecosystems of northern Australia and New Guinea...
Some species of jellyfish swim up river to breed. In areas with large tidal ranges, the outgoing tide may resulting in jellyfish hanging from mangrove tree branches like plastic bags.
These are the crabs that have their eyes located at the end of stalks.
Small and usually colourful crabs. The adult males have one enlarged claw that they wave around to establish territory, fight other males, and attract females.
Uca flammula, 'Flame Fiddler Crab'.
When a mosquito bites a human, they are inserting a long section called a stylet into the skin to draw out the blood. Like other flies, only the female bites, as she needs the blood to produce her eggs. Different mosquitoes attack different species of vertebrates, including frogs, birds and mammals. Particular species of Culex attack mainly birds, while others in the genus Aedes attack mammals. Some mosquitoes inject a compound through their saliva which reduces blood clotting; this is what often causes the bites to itch later on. The bite in the image above...still itches.
