GIANT TRIGGERFISH (Balistoides viridescens)
Length: to 80 cm
The largest triggerfish and one which can be very aggressive when guarding nests but may attack divers for no obvious reason.
Best to swim around large individuals at distance, rather than crossing its area. Usually seen singly on costal slopes near to deep water.
BLACKSPOTTED PUFFERFISH (Arothron nigropunctatus)
Length: to 30 cm
This species mainly lives on coral reefs, often sleeping in barrel sponges.
Highly variable, gray to brown or bright yellow, black spotted to various degrees. Occurs singly or in pairs.
STARRY PUFFER (Arothron stellatus)
Length: to 1,2 m
Largest of all puffer fishes, encountered to 60 m. Prefers reefs with caves and large sponges, usually seen singly.
Feeds on invertebrates, mainly echinoderms.
COMMON PORCUPINEFISH (Diodon hystrix)
Length: to 70 cm
This species inhabits coral or rocky reefs, usually seen singly, often swimming high above the substrate during the day.
Feeds on invertebrates, mainly shells and molluscs.
PAINTED ANGLERFISH (Antennarius pictus)
Length: to 24 cm
A very common but one of the most variable species, virtually appearing in all colors but blue and green, matching most sponge colors.
Inhabits coastal reefs, lagoons and slopes with corals, sponges or at night just out in the open on sand. We see them often in the Similan Islands and around Phi Phi Island.
