9p Coral Beauty Angel (Centropyge bispinosus).  Also known as Twospined Angelfish, Coral Beauty Pygmy Angel or Dusky Angel, the Coral Beauty Angel is a hardy saltwater angelfish, one of the most common saltwater angelfish.  It can range from a body color of deep blue/purple color with faint black lines to a light yellow or orange with blue or purple on the rear dorsal fin and tail.  The Coral Beauty Angelfish is a favorite Dwarf or Pygmy Angelfish species for aquariums due to its brilliant colors, hardiness, low price and ready availability. This fish is normally not as aggressive as many other Angelfishes, but some individual specimens may be territorial in smaller aquariums, particularly if they have been in the tank for a while.

17p Bigfin reef squid (Sepioteuthis lessoniana).  A species of squid found in the Pacific Ocean. It is a warm water-dwelling squid found in temperate and tropical regions. This species has been found to survive in various locations, including the Hawaiian Islands and Red Sea. They tend to remain close to the shoreline and are extremely sensitive to chemical changes in the water.  The bigfin reef squid eats a variety of different marine organisms. The squid's ten equally-long tentacles are used to capture prey. This species can eat up to 30% of their body weight per day. It reaches full maturity at around five months after birth. Males often compete with one another for dominance. When a pregnant female lays eggs, she attaches them to rocks, aquatic plants, and other surfaces. The eggs are laid in single strands.  (

24p Branching anemone (Actineria sp).  Large anemone (diameter 30 cm) with large, robust tentacles, densely covered with clusters of vesicles. Grey or greenish color.  It lives on sandy bottoms, in lagoon or in bay.  Expanded during the day.  Like all the Actinodendron species can inflict very painful stings.  It can expell the water that keeps it erect and disappear into the sand in less than 1 second.  (
