Pharaoh cuttlefish
The pharaoh cuttlefish is a large cuttlefish from the Sepia pharaonis group, found in the warm waters of the Indo-Pacific. Mantle length reaches about 42 cm and weight up to 5 kg. Like other cuttlefish, it has a well-developed nervous system and complex behaviour: it uses jet propulsion (including quick backward bursts), releases ink and changes colour and skin pattern instantly using chromatophores; it can also change the "texture" of its body surface with skin papillae for camouflage.

Myripristis murdjan
Red lionfish
The red lionfish (zebra lionfish) is a venomous reef fish of the family Scorpaenidae. It is easily recognised by its long, fan-like pectoral fins and dorsal spines with venom glands. Coloration is contrasting: white vertical stripes alternate with red, maroon or dark brown. By day it often hides in crevices and under reef overhangs; it hunts mainly at dusk and at night, ambushing small fish and crustaceans. A sting from its spines is very painful and can cause a severe reaction.
Pterois volitans
Zebra shark
The zebra shark is the only species in its family. It is easily recognised by its patterned colour, long tail and longitudinal ridges along the body. Its range covers the warm waters of the southern Pacific. It prefers coastal shelves of continents and islands and is often seen on coral reefs at depths of 70–80 metres or less. This shark is large, reaching over three metres in length, though adults are usually 2 to 2.5 metres.
