About this species

Giant morays can reach 3 m and are the largest moray species in the world. The constant 'breathing' open-mouthed pose isn't aggression — it's how they pump water across their gills. They're nocturnal hunters and spend daylight hours wedged into reef crevices, often with cleaner shrimp and wrasses tending their teeth.

Fun facts

  • Have a second set of jaws (pharyngeal jaws) deep in their throats
  • Hunt cooperatively with groupers in some reefs
  • Can live over 30 years
