- ‘There are frogfish that look like crabs; nudibranchs that look like something from Salvador Dali's most colourful dreams; devilfish with chicken's claws that look like nothing on Earth.’
- ‘Schools of pelagics patrol the pinnacle - devilfish, samson, amberjacks, jewfish, trevally, mackerel and bullseyes, as well as black cod, spangled emperor and snapper.’
- ‘Schools of the devilfish swarmed around the screaming multitude as they tried to float on broken planks to the opposite bank; the piranhas turned living flesh to whitened bones.’
- ‘Their names say everything - dragon fish, devilfish, viper fish, gulper eels, blacktail netdevils, ghost sharks.’
- ‘The first thing I saw was an inimicus devilfish.’
- ‘The rubble and bommies offer good hunting for leaf scorpionfish, ornate ghost pipefish and many small surprises, while out on the sand various sand octopus species are common, along with devilfish, robust ghost pipefish and more.’
