I, for one, welcome our new loner female, tool-using dolphin overlords.
from the article:
from the article:
As best the researchers can tell, a single dolphin may have invented the technique relatively recently and taught it to her kin. The simple innovation dramatically changed their behavior, hunting habits and social life, the researchers found. Those that adopted it became loners who spend much more time on the hunt than others and dive more deeply in search of prey. The sponging dolphins teach the technique to all their young, but only the females seem to grasp the idea.altho another article sez the technique confers no advantages. more broadly, i wonder if self-awareness is a necessary condition for tool use?
I think the sponging dolphins are just doing it for style points.

Assuming we don't just wipe them out though general environmental asshattery, I think it's pretty much inevitable that we're going to end up using the fruits of prosthesis research to give dolphins brain-operated robo-arms, and then all bets are off.

Putting a sponge on your dainty nose to avoid scoffing it is a pretty female thing to do.
The thing that pisses me off is all the species they talk about that manage to use only one tool. Nobody but us humans seems to have generalized tool use from one instance to the general idea of using multiple tools and inventing new ones. STUPID ANIMALS

The sex difference between tool-using and non-tool-using dolphins is very striking. This is fascinating food for thought with respect to the relationship between sex and gender. Thanks for posting it.

Stupid dolphins.
It's interesting, though, that typically only the females continue to use to sponge tactic. Of the one documented male to continue to use it to maturity, I wonder how his hunting skillz stack up with the rest of the pod? Also, I wonder how the female calorie expended/gained ratio in pod hunts stacks up against males, in general?

Only one older male dolphin continued hunting with a sponge. "He would go get a sponge and do it privately," Dr. Mann says. "It was like he was cross-dressing in private -- an old man out there sponging by himself."
okay, that's hilarious. like the boys think it's a girly thing to do? only girls protect their delicate snouts from the rough sand? are snout scrapes a sign of virility? a disdain for injury? is it unfashionable to wear sponges on one's snout? or is it that the males like hunting in packs so much that sponge diving is just too much bother?

I'm not a marine biologist, but I'd guess it's the last one. I also found myself wondering whether the one male who was sponge-diving was homosexual. (Not trying to be funny, really.)

Since male dolphins tend to be very aggressive pack hunters, and that sponge-gathering seems awfully tedious and solitary, I'd imagine it's just not ...fun. An older male dophin may not be up to full on pod-hunting anymore and find sponge-gathering easier.
Also, considering that Dolphins tend to be pan-sexual inter-species rapists, I don't you would could easily classify one as "homosexual".

When I was a kid, some other kids told me that homosexual meant a man who thinks he's a woman and a woman who thinks she's a man. I went in and asked my mom, if this is true, why doesn't a homosexual man just marry a homosexual woman? She told me that's not what homosexual means, and those kids were idiots. I now pass this piece of wisdom on to you.

Regarding the "he would get a sponge and do it privately" quote, it's important to note (as the article does) that this way of hunting is essentially a solitary one, so we should avoid projecting human social structures onto the behavior of this male dolphin. The fact that he obtained and hunted with a sponge "privately" is just part and parcel with that way of hunting. It sounds like the biologist who said this didn't have good grounds for making the analogy between the male dolphin and a human transvestite.

The male bottlenose dolphins of Shark Bay may be forming packs for reasons other than hunting:
So why do males form these alliances? The answer seems to greatly reflect human behavior: to get women. Male alliances typically "herd" females for anywhere from a few minutes to months(4) These herding events are not usually enjoyed by the females. Herding is often forcible with escape events and violence involved.(3) In a herding event males will surround the female or chase her. Aggression toward the female is common and can include: hitting with the tail, head-jerks, charging, biting, or body slamming.(3) Should the female try to escape, which often happens, the males will chase her more often than not. Of course the ultimate goal of a herding event is sex and the males in the alliance will take turns to make sure everyone has an equal share. If the alliance has three members, only 2 will herd the female and the third will stay behind. However, the individual who is left behind changes with every herding event so again all members have an equal chance at mating. (3)
In short, they gang up to rape. As you might expect, considering how difficult it would seem to be for an individual male to corner and rape a female.
Not so for us primates, is it?
I wonder how much of the selection pressure which produced these things we call hands came from the fact that they can facilitate rape by a solitary male.

Lady Cortez-Lee and Lord Galliano-Lee put on their suits and descend to to the Diplomatic Chamber. They're both pretty tired, the Lord had spent the entire afternoon with the Apaic Alliance Of West Africa and the Lady spent literally 3 days listening to the Pacific Kings sing of problems and status, and the new laws concerning krill production and farming.
While the Pacfic , or Bayleen Kings are vital to to the Free Atlantic food industry, they are ....awfully musty, and tradition demands a a full 78-hour discussion. In Whalesong. No Breaks. So she was understandably tired ....which may account for the problems and the chaos of later, but we'll never know, will we? Anyway they arrive at Chambers with Princess Ee and Master Oeeo at around 13 Hour Nova Honolulu Time.
It started off fine, the Delphic Empire is still very segragated, so Lady Cortez-Lee spoke only to Princess Ee and Lord Gallinao-Lee spoke only to Master Oeeo. It is not known what, exactly, was discussed, the records have been lost. But ..after the ritual offering of Salmon and Beef, Princess Ee became very upset and refused to ackowledge the authority of Lady Cortez-Lee. Master Oeeo was, as far as we know, alone with Lord Galliano-Lee at the Chambers.
According to news, Princess Ee was so upset at the Lady's proposal of a Mid-Atlantic farming ridge agreement that she stormed out of the meeting. Other reports say that Lady Cortez mentioned the sponge on the Princesss' nose and made a ..very dirty comment in Delphic about it and this caused the Princess to cut her oxygen tube and almost Kill Lady Cortez-Lee. The Lord was unable to be reached, but gossip says he was caught in mid activity with Master Oeeo. The kind of action strictly frowned upon in the Diplomatic cores. Other reports say they just had an argument, and still shared the Beef Offering.
It doesn't really matter. We all have to live with the results. The Tuna farms are a mess, the a blockade of Shrimp, and our own Chicken Farms are hurting. The Delphic Empire's new found lust for "traditional" food and boycott of "Land Fish" really hurt our own farmers. Actual out and out war would be impossible, of course, the Deep Ones would make sure of that, but the Apaic Alliance are getting upset and trying to get the Corvids to join in, but thankfully, the Corvids aren't big joiners.
