Natural underwater slinky

We don’t use the phrase “Just when I thought I had seen it all” because stories like this one are being shared around the globe:

Divers just found a giant natural slinky on the Great Barrier Reef

This tube-like structure measures over 2.4 metres (8 feet) in length was identified byJames Cook University’s Dr Blake Spady as the egg tube of the Diamondback Squid. The squid, which itself is around 2 metres in length, can lay over 40,000 eggs in one ‘slinky’. Sadly, she dies afterwards.

Swimming anemone?

We didn’t know that some anemones can swim! Check out this anemone avoiding a predatory leather star:

Octopus Balloon?

This video was captured by the Hercules ROV at a depth of ~2000m while scientists were exploring Southwest Baker Island in the Pacific Remote Islands Marine National Monument. AMAZING!

This octopus is believed to belong to the Cirroteuthidae family of cirrate octopuses (different from the Dumbo octopus), and lives in ocean depths where light does not penetrate the cold waters.

Cockatoo Squid

Last month, a cockatoo squid was spotted by the ROV Global Explorer at a depth of ~527m in the Gulf of Alaska. This squid is from the family Cranchiidae and its chic pompadour is actually the animal’s arms and tentacles folded back over its head. Like octopuses and other cephalopods, the cockatoo squid is equipped with chromatophores (pigment-carrying cells) that allow the animal to change colour and reflect traces of light. Amazing likeness to our local fauna!

Cockatoo Squid: Gulf of Alaska Seamounts 2019

It's a cockatoo squid (Cranchiidae)! Filmed by the Global Explorer remotely operated vehicle at 527 meters (1,729 feet) depth along the Gulf of Alaska continental slope during the Gulf of Alaska Seamounts 2019 expedition. Pretty, huh?For more from this expedition, visit:
