The Glass Octopus vs. The Blue. Ringed Octopus By- Chloe France Mrs. Heer, Language Arts Mod- 7/8

Thesis Statement • The Glass Octopus and the Blue- Ringed Octopus may both be octopi, but they are two very different organisms.

What do you think of when you hear: “Octopus”?

The Octopus • When people hear: “Octopus”; they think huge, terrifying sea monster. • In reality, most octopi are miniscule or not even bigger than your hand! • All octopi have the 3 basic body- parts: the mantle, 8 legs with suction cups or “Suction Disks”, and the ink sac.

Commonness of the Octopus • Most octopi aren’t very common, they mostly stay out of the human eye’s path. • Octopi are actually very shy animals, they don’t interact with any other animals much. • The Glass Octopus and The Blue- Ringed Octopus are VERY uncommon to people in the U. S. They’re more common around Australia and near the Caribbean.

The Blue- Ringed Octopus Habitat • Mostly found in “Temperate waters around Southern Australia”. • It can also be found in shallow reefs near: Australia, Japan, Papua New Guinea, Solomon Islands, Philippines, Sri Lanka, and Indonesia. • Found closer to the Eastern North Atlantic Ocean. , Japan, Papua New Guinea, Solomon Islands, Philippines, Sri Lanka, and Indonesia

The Glass Octopus Habitat • Mostly found in the Caribbean. • Found in the “Twilight Zone” of the sea. • Usually ranges around 0 -50 meters in depth.

A little more about the Blue- Ringed Octopus • Has poisonous venom. • Venom can kill in minutes after injected into you. • Victim's muscle movement, including breathing-muscles are gradually slowed and eventually stopped. • When excited, provoked, or angry, it becomes bright yellow in color with bright blue rings.

Example of Excited, Angry, or Provoked Blue- Ringed Octopus.

Glass Octopus Body Parts • Made up of a mantle, tentacles, suction disks (cups), ink sac, funnel, and it’s eyes are rectangular shaped. • Adult mantles are about 45 cm long. • Their suction disks (cups) are small, widely separated, and single series. • It’s eyes are wide and rectangular on opposite sides of their heads.

Example of The Glass Octopus’ rectangular eyes and transparent color.

Blue- Ringed Octopus Body Parts • It is usually brown with dull blue-ish rings scattered all over it (As I said; when angry, excited, or provoked it turns bright yellow). • Made up of a mantle, tentacles, suction disks (cups), ink sac, poison gland, and funnel.

Glass Octopus & Blue- Ringed Octopus Behaviors • Usually very shy, as all octopi are. • Doesn’t try for contact with humans and other organisms. • It’s whole life is basically to find a mate, and reproduce.
