Sea Foam is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolved organic matter. These compounds can act as surfactants or foaming agents. As the seawater is churned by breaking waves in the surf zone adjacent to the shore, the compounds trap air, forming bubbles which stick to each other through surface tension.

Living Fossil
The Long-tail Tadpole Shrimp is a freshwater crustacean resembling a miniature horseshoe crab. It is one of the oldest animal species still in existence. The Long-tail Tadpole Shrimp is considered a living fossil because its basic prehistoric morphology has changed little in the last 70 million years, exactly matching ancient fossils.

Black-headed Honeyeater
The Black-headed Honeyeater is a species of honeyeater endemic to Tasmania. Its natural habitats are temperate forests and Mediterranean-type shrubby vegetation. Despite the name, insects form the bulk of its diet. The Black-headed Honeyeater specializes in foraging among the foliage of trees, unlike the related Strong-billed Honeyeater (the other honeyeater species endemic to Tasmania), which probes the trunks for prey.
