The Coconut Octopus (Amphioctopus Marginatus) can have a body sac measuring up to 10 cm and arms that extend to 20 cm in length. Found at depths of up to 200 m, it is easily accessible to divers even at just 10 m. While it is active during the day, its primary hunting activity occurs at dusk. Its diet includes small fish, shrimp, and crabs. This species is also known as the veined octopus due to its distinctive markings, which remain visible regardless of its color.

The Arrowhead Soapfish (Belonoperca Chabanaudi) can often be found in the dark recesses of the steep walls around Bunaken. The solitary creature usually stands upside down in the shade, waiting for dusk. It only hunts for small fish and shrimps under the cover of darkness. Like all soapfish (Serranidae), it can release the poison grammistine through its skin when in danger.

The Broadclub Cuttlefish (Ascarosepion Latimanus) has eyes positioned laterally like a fish, but it can rotate them forward to create overlapping fields of vision. This allows it to accurately gauge distances to its prey as well as to unfamiliar objects, such as divers, while hunting.
