Distribution and habitat preferences

Areas of sand close to reef margins.

Can be seen in most locations where sandy bottoms lie adjacent to reefs.

A solitary species found on sandy bottoms near rocky or coral reefs. Usually found in deeper water but moves onto the reef flat and into shallow lagoons at high tide. Occasionally covers itself with sand, leaving only its eyes and tail visible.

Behaviour

Active both diurnally and nocturnally, although more usually at night and late afternoon. Feeds on invertebrates from the sand and digs actively when hunting.

Danger

  • requires treatment - The tail has a poisonous spine about half way along its length, which can be used to inflict a painful stabbing wound if the ray is stepped upon. Walk with care in shallow water on reef flats, and stand still if a stingray is near - they will always move away if given the chance. For first aid click here.
