I find cuttlefish fascinating. They are social, relatively
intelligent, can communicate, able to grasp and manipulate things.
It seems like they were all set to become the dominant large life
form (instead of humans).
A mystery: they don't live a long time. Usually "intelligence" go
with a rather long life, but cuttlefishes live one or two years.
Yes - I find that surprising also.
Hard for them to dominate, also, as they have few protections, no
shelter, and are edible for many predators, including humans.
One could say the same about early home 2 millions years ago. The
invention of the throwable spear changed all that.
Yes.
They
survive by hiding and fooling. They can hunt with hypnosis (as you
can see in the video).
I feel privileged that these wonderful animals (giant cuttlefish) can
be found less than 200 metres from my house. I have often observed
them when snorkling or scuba diving.
I'm just jealous, really. I've seen them alone, confirming the
solitary status but also in groups, and have wondered whether there
is some group cooperation thing happening outside of mating, as they
seemed often to be moving in one direction, which could be of course
just getting away from huge yours truly.
You are privileged indeed.
I had to laugh at the Texan prof's comment that they are as least as
smart as fish.
That is weird indeed. fish are not known to be particularly clever.
What's funny is that he seemed scared of peer consensus, maybe from
the rival funding dolphin learning research camp or something, to
finally aim quite low, leaving everything else to "what we still
have to learn". But they have nothing to hide in this regard: they
live two years, go through that one mating cycle in which the males
are capable of cross dressing to fool the huge machos, and the
females acknowledge this through some control over sperm selection.
Some humans of both genders do not display that level of
intelligence, lol!
I do have a habit of underestimating fish intelligence,
Me too ...
... and overestimating the human one ;-)
but IMHO their intelligence equals that of some mammals or birds, and
clearly outclasses fish.
I agree.
I think I mentioned the anecdote which
convinced me they exhibit a second order theory of the mind, which may
well be sufficient for consciousness.
Which I call self-consciousness, and I think this is already
Löbianitty.
I do think that all animals have the "first order" consciousness,
they can feel pain, and find it unpleasant, but can't reflect on it,
nor assess "I feel pain". they still can react appropriately. I m
not sure, but it fits better with the whole picture.
Also the survival of the little flamboyant one, that just gave up on
swimming, mostly marching the sea floor, totally exposed to all
predators, not bluffing poison because it actually is poisonous;
when the rest of its kind is a delicacy for anything larger.
Strange that the predators believe the display of colors; "OK, we
believe you little guy" without having gone to the lab... and that
this one survived, not by speed, or camouflage but by disco sign
that reads: "remember, I'm not fooling around, these colors are for
real. I really am not like the rest of my kind, you like to eat. We
get that, and we have an update. That's why I'm not swimming away.
Simple really: you eat me, you're in trouble or you die. You better
swim on and let me do my things here, k? Good." PGC
The champion of faking is no more faking anymore, LOL.
Well, if all apparent food was edible, faking would no more made
sense. May be there has been a competition among species of
cuttlefishes the one being really not edible, and the other developing
tools to look like them. Of course cuttlefishes fakes also rock, or
the predators itself.
Cuttlefish can imitate in a second, what some jumping spider took I
don't know how many millions of year to do, like imitating perfectly a
non edible ant. Note how it uses her front legs to imitate ant's
antenna!
