New animal obsession: Octopus
New animal obsession: Octopus
The octopus is one of the more intelligent creatures on Earth. I mean not like people, but they’re pretty damn smart for being boneless underwater lumps of flesh. Sy Montgomery of Orion Magazine got a chance to meet an octopus close up, and he was amazed at the creature’s apparent intellect and emotional response.

Cuttlefish (Sepiida) are not only incredible masters of colour change, they also use visual cues to determine how best to posture themselves for camouflage that is positively seamless. Check out these images from the lab as well as the natural environment. Awesome.

First Tattoo, figured I’d get some input!
PROMACHOTEUHID SQUID has creepy “teeth”

Promachoteuthis sulcus is known from a single specimen collected in the south Atlantic at a depth of 1759-2000 meters. The holotype* is an immature female with a mantle length of 25mm. Its diagnostic characteristics include tentacles that are thicker at their base than the arms, and arm suckers that are bigger than the suckers on the tentacle clubs. However, the thing that got this obscure little squid noticed was this photo of its mouth, showing what seem to be disturbingly human-like teeth.
P. sulcus is known from a single specimen caught by the German research vessel R/V Walther Herwig in an open net off Tristan Da Cunha, southern Atlantic Ocean, at a depth of 1750–2000 m.

The firefly squid (Watasenia scintillans) (also known as sparkling enope squid) is a small member of the squid family, growing to a length of only 3”. It is found at depths of 600-1200’ in the Western Pacific ocean. What makes this squid so beautiful and amazing is that it is bio-luminescent; equipped with special light-producing organs called photophores. These photophores are found on many parts of the squid’s body and emit a deep blue light. The lights can be flashed in unison or alternated in an endless number of patterns. These light shows are thought to serve several functions. They can be used to communicate with potential mates or rivals. They may also be used to disguise the squid’s shape and confuse predators, allowing it to escape.
Reasons why octopuses in general are really weird:
- some have three hearts
- and venomous saliva
- and a hidden parrot-like beak
- they can change the color and texture of their skin with incredible ease and speed (they are much better at it than chameleons)
- they have “intelligent arms” that don’t seem to need instructions from the brain to perform certain actions
(this is a giant pacific octopus.)
I love octopuses
