Can Patience tell time?

I always feed my tank critters around the same time; midnight. We got in the habit long ago, when my big polychaete worms would not come out to feed in daylight. I liked to watch them, so the diurnal animals got used to it, too, and I haven't made any changes, even though the worms are gone.

Almost every night, now, starting a few minutes before midnight, I find my grainy-hand hermit, Patience, with her "nose" up to the glass in the front of the tank, waiting. At other times, she's roaming, but she knows supper time.

And, since I handled her so much when she was sick, she takes bits of food directly from my fingers. (All the other hermit crabs either hide or run if my hand gets too close.)

Patience, completely over her illness, eating a dried fish steak.

I find myself wondering, these days, about animal intelligence, about memory. How much of the behaviour of a crab or a shrimp, or of Patience, the hermit, is instinctual, and how much is based on what they have learned about the world? It seems that every few days I find some article about the intelligence of apes, dogs, horses, crows, whales, dolphins, and even little fish. How far down does the chain go?

Did my polychaete worms adjust to me as much as I adjusted to them? Were they waiting for the daily handout, down in their burrows?

Questions, questions.

  1. how neat. every 6 months when we change our clocks for DST, my animals take a few weeks to adjust to the 'new time' for feeding schedules.

  2. I fsh sat a couple of gold fish one time. They were almost dead by the time their owner arrived home - almost belly up buy still only side up. The next morning after she returned-- swimming around as happy as gold fish!

  3. I'd like to think so. There is much more to the world than even what we observe.

I'm having to moderate all comments because Blogger seems to have a problem notifying me. Sorry about that. I will review them several times daily, though, until this issue is fixed.

Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
