- The deepest ever sighting of an octopus has been made by cameras on the Indian Ocean floor, 7,000m down in the Java Trench. Researchers, who report the discovery in the journal Marine Biology, say it's a species of "Dumbo" octopus (genus Grimpoteuthis).

- Using MRI, researchers have discovered and described previously unknown major neural pathways in a bigfin reef squid (Sepioteuthis lessoniana). "We can see that a lot of neural circuits are dedicated to camouflage and visual communication," said Wen-Sung Chung. Paper in iScience: "Toward an MRI-Based Mesoscale Connectome of the Squid Brain", Chung et al.

- 2019-08-06 Octopus Bites Captor (KIRO)
- A human participant in a fishing derby in the Tacoma Narrows posed for a photo contest with a captured octopus on her face. The octopus bit her in self-defense. The human eventually went to the emergency room. "And I'm still in pain," she said. "I'm on three different antibiotics. This can come and go, the swelling, for months they say." She says the whole painful experience taught her a valuable lesson about handling live octopuses, which have powerful beaks and poisonous venom. No word on the condition of the octopus.

The southern sand octopus (Octopus kaurna) lives in sand flats around southern Australia and Tasmania. Unlike most octopuses, the sand octopus cannot change its color. Instead it uses its siphon to blast sand beneath it, suspending the sand in water, making its own quicksand that it can pull itself down into for shelter.

- The Asperoteuthis mangoldae squid is a recently discovered deep-sea species that was just seen alive for the first time! Researchers think this unusual squid's tail may help it mimic other animals, like a stinging siphonophore. Also from Nautilus: Rare encounter with piglet squid.

- Biologists have discovered that the genes that guide the initial formation of legs in us and other vertebrates also guide the formation of the squid's lens. The find is yet another example of how nature recruits genes used for one purpose to do another job for the body.
