Transcript of Dumbo octopus
Four modes have been observed in dumbo octopuses: crawling, take-off, fin swimming and pumping and one other mode called umbrella-style drifting.
Grimpoteuthis is known to be buoyant, which allows the animal to drift passively with its fins expanded.
They can be up to 20cm in length, and can be many different colours.
The dumbo octopus developed ear-like fins to make it a better swimmer.
They also have the great ability, they can colour the outer layer of their skin at any time to protect themselves from predators. what the dumbo octopus eats They hover above the sea floor, searching for polychaetes, pelagic copepods, isopods, amphipods, and other types of crustaceans for food. The Dumbo octopuses way in eating food is slightly different as it swallows its prey whole, which is different from any kind of octopus. Thank you for listening to my presentation I hope you have learned something about Dumbo Octopuses or Grimpoteuthis. Have a good day! Thank you for watching! Behaviour The Dumbo octopus swims by flapping its fins, or by shooting water through its funnel. It can use all of these techniques at the same time or only one at a time. Some spend most of their time swimming and others spend more time on the bottom of the ocean floor, flattened out.
