Does anyone already know the dumbo octopus? Dumbo here does refer to a flying elephant with Walt Disney's long ears.
Like dumbo, octopus living in the deep sea also has a very wide ear-like fins. That's what makes it named dumbo octopus (Grimpoteuthis).
Octopus dumbo itself live at a depth of 3,000 to 4,000 meters under the sea. That means their natural habitat is difficult for human beings to access.
But now for the first time you can see the newly hatched dumbo octopus after the researchers caught the animal in the cephalopod group (the animal with the head surrounded by the arm or tentacle).
The National Oceanic and Atmospheric Administration (NOAA) expedition team first managed to record a newly hatched dumbo octopus on board the NOAA research vessel.
Before being taken to the ship, they find something that looks like a small brown golf ball attached to a coral branch in the Northwest Atlantic.
They then collected some samples with the aid of a remote-operated expedition ship (ROV) to collect eggs from coral reefs as far as 2,000 meters below sea level.
"From what has been collected, it is clear that it is a kind of egg, some (eggs) that are opened first empty, the next there is a kind of white gelatin in it, and the last sample yields the specimen as described in the paper,"

KOMPAS.com - Does anyone already know dumbo octopus? Dumbo here does refer to a flying elephant with Walt Disney's long ears.
Like dumbo, octopus living in the deep sea also has a very wide ear-like fins. That's what makes it named dumbo octopus (Grimpoteuthis).
Octopus dumbo itself live at a depth of 3,000 to 4,000 meters under the sea. That means their natural habitat is difficult for human beings to access.
But now for the first time you can see the newly hatched dumbo octopus after the researchers caught the animal in the cephalopod group (the animal with the head surrounded by the arm or tentacle).
The National Oceanic and Atmospheric Administration (NOAA) expedition team first managed to record a newly hatched dumbo octopus on board the NOAA research vessel.
Before being taken to the ship, they find something that looks like a small brown golf ball attached to a coral branch in the Northwest Atlantic.
They then collected some samples with the aid of a remote-operated expedition ship (ROV) to collect eggs from coral reefs as far as 2,000 meters below sea level.
"From what has been collected, it is clear that it is a kind of egg, some of which are first opened, the next there is a kind of white gelatin in it, and the last sample yields the specimen as described in the paper," said the researcher. dilansir Science Alert, Tuesday (20/2/2018).
After the samples are collected, they put the egg into a bucket of water and store it in the cold room on the ship. They recorded their eggs measuring 14x19 millimeters unbroken.
When the bucket of eggs will be removed from the room, it turns out the eggs begin to hatch. Beginning from the posterior or the back, then the fins, the last tentacle.
"When the fins appear in the bucket, it's very clear that he is a dumbo octopus," said Elizabeth Shea from the Delaware Museum of Natural History.
mentioned dumbo octopus that just hatched initially not much move. The researchers suspect it is because they hatch too early.
Despite hatching faster than his time, the dumbo octopus already has a complete organ and soon he starts to move.
After the researchers observed for two hours, they took care of octopus, egg, and membrane for long-term storage.
They also performed magnetic resonance imaging (MRI) scans and a three-dimensional reconstruction of an octopus baby to study its anatomy.
This confirms the genus of the dumbo octopus into the Grimpoteuthis, although the exact species is not yet known.
They also discovered that the octopus is fully formed from the beginning including everything needed to start living independently in their environment.
"The virtual exploration and 3D reconstruction of the internal anatomy of these deep-sea creatures is very open, I am impressed with the complexity of the central nervous system and the size of the fin as well as the inner skin.For me who is a zoologist, the most interesting aspect of our findings is the close interaction between octopus octopus eggs and Coral reefsdeep sea, "says zoologist Alexander Ziegler of the Rheinische Friedrich-Wilhelms-Universität Bonn, Germany.
She finds cartilage or cartilage on the fins, the skin of internal cartilage, and her muscles are strong enough to start swimming.
In addition, the dumbo octopus also already has a number of well-developed suckers.
The dumbo octopus has a fully developed eye that can see. Plus it has a large yolk sac containing enough nutrients to keep food there for a few days while learning to get its first meal.
Evidence video of mature dumbo octopus reveals that they will be a pretty underwater dancer.
Here is the recording of the behavior of the dumbo octopus after hatching.
