The Snowflake Moray Eel, along with other species of morays, have pharyngeal jaws, which are a second set of jaws located in the throat or pharynx. This species is an unconfirmed hermaphrodite, but there have been records that they are able to change sex during their lifetime. Snowflake morays are also scale-less, secreting a mucus over their skin that allows for easy maneuverability in and around holes in their environment.
Stonefish are the most venomous fish known; stings can be fatal to humans. Most stonefish stings occur as a result of stepping on the creature which forces venom into the foot, while it is less common for the fish to sting when it is picked up. Stonefish stings can occur on the beach, not just in the water, since stonefish can survive out of the water for up to 24 hours. They are not easily seen as they look similar to rocks or coral.
