|---|
| SCIENTIFIC NAME: | TYPE | DIET CARNIVORE | GROUP | LIFESPAN | SIZE |
|---|---|---|---|---|---|
| - Octopoda - class Cephalopoda | -Invertebrates -is a mollusk (like a clam) | - Meals can include clams, shrimp, lobsters, fish, sharks and even birds. | -Octopuses are solitary animals that live alone in dens. | -Giant Pacific octopus: 3 – 5 years - antrctic octopus unknown lifespan | It can grows to at least 28 cm in mantle length and 90 cm in total length. |
THE PLACE IT LIVES – DEEP-SEA HYDROTHERMAL VENTS
- lie more than a mile and a half below the sea surface
- total darkness.
- searing hot vents support a ecosystem
- support species of animals from blind shrimp to giant tube worms
ABOUT THE DEEP SEA OCTOPUS’ INK SAC
- Antarctic octopus has adapted to living in complete darkness
- it has been discovered that this octopus has no ink sac because it can escape with out it
- Deep Sea water is so black that it does not need it.
ABOUT THE DEEP SEA OCTOPUS’ COLOUR
deep-sea octopuses have little need for colour or camouflage.
ABOUT THE DEEP SEA BLOOD AND HEARTS
- has three hearts, and blue blood.
- 2 hearts pump blood to the gills to collect oxygen
- there is a heart to circulate blood to the rest of the body
- blood contains the copper-rich protein hemocyanin
- hemocyanin is more efficient than hemoglobin for oxygen transport
- hemocyanin can transport oxygen at very low temperatures
- hemocyanin can gather oxygen even at low oxygen concentrations
