Weird n' Wild Creatures Wiki

The blue-ringed octopus seems tiny and delicate, but this crafty sea creature has enough poison to kill an animal as big as a horse with a single bite. The octopus often hides in and around coral reefs and when threatened, shows off its blue rings to warn off attackers.

Packing Poison: This octopus’ two poison glands are each about as big as the creature’s brain. The poison, one of the deadliest of all known toxins, attacks a victim’s central nervous system, causing paralysis and a complete body shutdown.

Fatal Beauty: The blue rings make the octopus startlingly attractive, but the colors are a warning. The blue rings enlarge and flash to advertise the creature’s toxic threat.

Double Whammy

Each octopus tentacle has about 40 suckers.

Having no bones in its body, the blue-ringed octopus can hide in very tiny spaces. When prey happens by, it has a choice of how to make a kill. It can spring out and deliver a poisonous bite, or it can simply release its toxins into the water, killing fish as they take in the poisonous cloud through their gills. The octopus uses its sharp break to chew up the dead prey.

20/20 and Beyond: The blue-ringed octopus hunts mainly by sight. It can see so clearly through the water that it instantly recognizes whether passing prey is a favorite food.

Mad Grabber: The creature can’t see into rock crevices, however, so it uses its long tentacles to search for food and grip prey tightly. The suckers on these long arms are sensitive to texture and even taste to let the octopus know when it has found something good to eat.

Blue for Danger

  1. Young reef fish, such as this coral trout, are often too inexperienced to know the danger the blue-ringed octopus presents.
  2. Going in on the attack, the fish is soon caught in an eight-legged grasp and a bite from the octopus sends toxins through its body.
  3. The coral trout is instantly paralyzed. It has learned too late not to mess with the deadly octopus.
