Christmas Tree Worm
The Christmas tree worm is a tube-dwelling polychaete worm (Serpulidae) living in close association with corals. Builds a calcareous tube in the skeleton/on the surface of the coral and extends two spiral "Christmas trees" (radioles) outward, which serve for respiration and food filtration; quickly retracts when threatened.

Mosaic jellyfish
The mosaic jellyfish (also known as jelly blubber or blue blubber jellyfish) is a rhizostome scyphozoan jellyfish common in coastal waters (shallow bays and estuaries). The bell is dome-shaped, usually 30–35 cm in diameter, and colour ranges from milky white and cream to bluish; the surface may be finely granular and the overall pattern looks "mosaic-like". There are no long marginal tentacles; instead, under the bell there are large oral arms and eight short, thick, fringed mouth arms. It feeds on plankton and small organic particles by filtering water; it sometimes forms large blooms.
