Nusa Penida - List of fishes

The large pectoral fins of this fish serve as a fish net to capture prey. Its color (alternating dark and light bands) indicate to predators that it is poisonous: there are poison glands in the skin covering its spines. It can cause serious or fatal accidents.

This moray is narrower than most other species. Over time, the male becomes a female (protandrous hermaphroditism). This sex change is accompanied by a color change. This moray adapts easily to life in the aquarium.

The two-lined monocle bream is widespread in the coral reefs of the Indo-Pacific region. Adults often live in pairs and primarily hunt at night. Juveniles mimic the striped poison-fang blenny and adopt similar behavior to evade predators.

The moon wrasse inhabits the coral reefs of the Indo-Pacific. This species is sometimes referred to as the moon wrasse due to the shape and yellow color of their caudal fin. This wrasse primarily feeds on small invertebrates residing in the rocks and fish eggs.

The twotone tang, like its counterparts, possesses scalpels at the base of the caudal fin. In times of danger, it can extend two small blades for protection against predators. Adults of these fish typically live in groups of around twenty individuals. They gather in large schools to spawn during the breeding season. They are exclusively herbivorous and graze on algae in coral-rich areas.
