I saw a reputable video, many years ago, and it did focus on the amazing intelligence of these invertebrate.......They aren't one of the most intelligent animals on Earth. They are intelligent for an invertebrate.
Interesting and thanks.They are interesting, amazing, and intelligent for what they are. Mainly they are just different.
There are intelligent but much of what they can do is controlled by a distributed network meaning their main brain isn't involved. There are also distinguished from most other highly intelligent animals in that they don't live long.
A large Giant Pacific Octopus lives about 3 years. They are also not at the top of their food chain. They get eaten all the time. They are good problem solvers. There are cases of them escaping their display tanks in aquariums around the world.
There was on in New Zealand I believe where it got out and managed to go back out to sea. However in the Seattle Aquarium (I volunteered there as a naturalist and a diver briefly) one escaped it's public display tank and was found dead on the floor the next morning (smart and not so smart).
What they can do in the wild is indeed wild and I have witnessed a lot in 1,000 or so dives in the Pacific Northwest. The implication though seems to be that they are one of the smartest animals in the world up there with an Orca for example. This is just an overstatement.
An Orca has a bigger brain than we do and lives as long as we live. An octopus is in the "snail" family. The amazing part is just try is it so smart for what it is? Of course the ability to change color, skin texture and to squeeze though any opening as long as it can get it's beak though (which is the only hard structure in its body) is amazing to watch.
I've never heard the term "Grampus" but Orca and Killer Whale are the same thing. They are large dolphins that the Native American Indians called Killers of Whales. They kill whales, they aren't whales.Interesting and thanks.
Some of the amazing stuff Orcas get up to is mind boggling!!
Question: Grampus/Orca/Killer Whale...are they all the same species? dolphins?
While certainly it is not heard much [I came across it many years ago] and am always looked at funny when I raise it, I always associated it with another name for an Orca/Killer Whale.......I've never heard the term "Grampus" but Orca and Killer Whale are the same thing.
If we were the equivalent at problem solving in our lifetime we could have a Prime Minister age 6 monthsThey are good problem solvers.
Are there any non-mammal tool users other than octopuses?I saw a reputable video, many years ago, and it did focus on the amazing intelligence of these invertebrate.......

Not sure exactly where they would rank, but certainly up there!!
Birds.
Sorry, I meant to ask if any other non-mammal aquatic animal uses tools.Birds, certain fish, ants, the list goes on...
Decorator crabs.Sorry, I meant to ask if any other non-mammal aquatic animal uses tools.

It lives in symbiosis with the Anemones.clown fish ?
does it recognize the function of the stinging sea anemone ?
http://tolweb.org/treehouses/?treehouse_id=3390#Where do Clownfish Live?
Clownfish live at the bottom of the sea in sheltered reefs or in shallow lagoons, usually in pairs. Clownfish have a special relationship with the anemone and are very important to them. They are a large help to the anemone as they clean the anemone by eating the algae and other food leftovers on them. They also protect the sea anemones by chasing away polyp-eating fish, such as the butterfly fish.
crabs obliviously
Tool use among aquatic animals is rare but taxonomically diverse, occurring in fish, cephalopods, mammals, crabs, urchins and possibly gastropods.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4027413/#While additional research is required, the scarcity of tool use can likely be attributable to the characteristics of aquatic habitats, which are generally not conducive to tool use. Nonetheless, studying tool use by aquatic animals provides insights into the conditions that promote and inhibit tool-use behaviour across biomes. Like land-based tool users, aquatic animals tend to find tools on the substrate and use tools during foraging. However, unlike on land, tool users in water often use other animals (and their products) and water itself as a tool.
Any sea dweller that uses empty shells for protection or habitat is basically a tool user.the eel and shark hunt together (i forget which, cross species co-operation as a pack ?)
is pack hunting flushing and swapping of roles of eating for flushing a function of tool recognition ?
But AFAIK, most deep ocean dwellers have symbiotic relationships with other species.
Like some squids which use bioluminescent bacteria as a cloaking device. (Hawaiian Bobtail squid).
