The genus Synalpheus is also unique as it contains the only known eusocial aquatic species .... in the world.


They live inside a few specific sponges, in colonies of up to 350 individuals with only one breeding queen.
It is believed they evolved eusociality because they are fortress defenders.





How cool is that, these shrimp living in, and defending their fortress form invaders, ruled by their queen.



Apart from insects and the shrimp the only other eusocial animals are Naked mole-rats and Damaraland mole-rats.


They are one of the weirdest most amazing animals ... in the world.


They are the only eusocial mammals. They have a queen, up to three reproductive males and division of labor amongst the workers.



They are unique in that they defy the Gompertz–Makeham law of mortality. At least as far as they have been studied.
The law just states that there is an age related component to mortality rates that increases exponentially as you get older.
From a glass half empty perspective, the older you are, the less likely it is you will get much older.


Adult Naked mole-rats seem to have about a 1 in 10000 chance of dying in any year, irrespective of how old they are! In fact, it even seems to get a little lower the older and presumably more experienced they get.


Not only are they eusocial and don't seem to age, they are also cute,
https://upload.wikimedia.org/wikiped...d_mole_rat.jpg

  • can swivel around their front teeth independently
  • 1/4 of their muscle mass is in their jaw muscles
  • they always show their teeth when smiling, their lips close behind their teeth
  • they can run as easily and fast backwards as forwards
  • are very resistant to cancer
  • can live with very little oxygen, up to 5 hours with 5%, showing no distress and carrying on as usual, or 18 mins with nothing
  • they are resistant to certain types of pain
  • they also do not thermoregulate but are thermoconformers.


They are also really, really, ugly.

Add a cup of water to a cup of alcohol and you get less than 2 cups of mixture.

Resulting in a more dense solution.

I have to admit that you have come up with a novel way to maintain credibility. The solution is more dense than the alcohol was but less dense than the water was.

You are talking about a completely different scientific fact than bobdroege7 is. I'm not sure how bobdroege7 could have explained that to you any better.

I wonder what an ugly one looks like...

(You know how there are some cute dogs and some ugly dogs?)

Oh, wait. Maybe that was an ugly one.

I think that clears up the contradictory statements nicely.

If you look at the posts from the beginning you may appreciate the nature of the misunderstanding. If indeed that is what it is.

It is a scientific fact that any sufficiently long thread on ISF will eventually degenerate into a couple of posters arguing about some trivial point.

My apologies everyone.
I posted that pick since it was in the wiki commons, it's absolutely not the best one to illustrate their cuteness.
That photo is in fact captioned Angry naked mole rat of the female gender, so probably the worst.


What if they looked the way their brains felt?
In their minds they are all teeth.
Behold the mole-ratunculus!


From this paper Somatosensory cortex dominated by the representation of teeth in the naked mole-rat brain.


What if we all looked like that.

Not all that scientific but I like the 3, 4, 5, triangle.

For the un-mathematic applying Pythagoras, where in any right angled triangle the sum of the squares of 2 smaller sides, equals the square of the hypotenuse.

I have used this many times to make a big and accurate square, when laying out foundations. All you need is a piece of string.

So the reason it's dark at night must be because when the sun is below us the light can't go that far uphill.

10 factorial seconds is precisely 6 weeks.

To within a few percent, there are pi seconds in a nanocentury.

Can confirm. Neat coincidence there.

Yeah, neat coincidence. You can even find some direct correspondence in the expansion of the factorial. The 7 (for days in a week) and 6 (for 6 weeks) are directly present. 2 times 3 times 4 is the 24 hours in a day. The other factors (5 8 9 10) multiply out to 3600, the number of seconds in an hour.


ETA: BTW This doesn't add much to the original coincidence, there are only so many ways the prime factors can be arranged.

This is more political/geographic then "scientific" by most definitions, but whatever.

The United States of America is a country on the (brace yourself) American continent that is (spoiler alert) a collection of states.

But the amount of land that is outside of the 50 states that is still part of the USA is striking.

And I'm not just talking DC or the various territories or holdings. 28% percent of the United State's total land area... doesn't belong to any of the individual states, it belongs directly to the Federal Government.

And the weird thing is how uneven this is as you go west. On the east coast there's barely any Federal Land but as you go west more and more of the land isn't owned by the states that the land is in. East of the Rockies and almost no state has more then 5 or at most 10 or so % of their land owned by the Federal government (and many have essentially none) but cross the Rockies and every state has a huge percentage of land that's not theirs. State laws don't apply, state taxes aren't collected, and the states have no say in what happens on them.

Five states have more Federal land than State land within their borders.

In New Hampshire a pitting .4 percent of the land inside the state boundaries of New Hampshire is Federal Land.

On the other end of the spectrum we have poor Nevada where a whopping 84.5 percent of the land in Nevada... isn't Nevada. Nevada is 110,567 square miles, the 7th largest state and roughly the size of Ecuador but only ~17,130 square miles of that is actually "Nevada." The rest is Federal Land full of nuclear bomb craters and recovered crashed alien spacecraft (citation needed.)

I wonder if this is some sort of "lost" political divide in America. The use of Federal Land within state boundaries pretty routinely, especially when we're not talking National Parks but less savory things like toxic waste dumps and the aforementioned "Hey Nevada we're going to nuke your state a total of 1,021 times, is that cool? Just kidding we don't care if it's cool or not. Actually just kidding we've already started and didn't tell you."

Steel beams don't need to melt to lose their integrity.

In fact not even halfway to melting point, the strength of structural steel is reduced by about half, varying with grade, but not significantly.
