Crab

Post by Erland R.N. »

Crap, had no flash when I had to photograph a crab in low light.
Image
Fresh water crab, Wakkerstroom, South Africa.
5D, Sigma 150 + 1,4x, slightly cropped
f/9, 1/50 sec, iso 3200, at 3 pm in the afternoon.

First time I saw this crab species, was when an individual was sitting nearly one meter up a tree stem.
:D
They were certainly fun to watch. Mostly they would slowly move toward the water, if they were disturbed, but if I got too close, they changed tactics, turned towards me and tried to look big and scary.

f/5.6, 1/80 sec, iso 1600, at 6 am in the morning.

Have never seen anything like those crabs.

Reminds me a lot of the mangrove crabs I saw in Florida.

http://en.wikipedia.org/wiki/Mangrove_crab -- no pics, but a zillion links.

Tree-climbing crabs surprised me too, but I guess there are even species that climb tall palm trees! :shock:

Nice closeup of the eye -- shows off the joint at the base really well.

Very interesting creature Erland...super shot of the eye. I like the little bead things to the right, over the mandibles.

Hi Erland,

There is some really interesting detail edging the carapace and attractive texture to the surfaces too. Do you have any more close-up photos of this plucky little character?

Thank you for comments.

Yes, seeing the pictures as I got home, I noticed these interesting details too. But I really had no oppertunity to photograph close up in good light, and the crab in the top picture, was kind of hiding.

I think I read somewhere that they found a new species of something living in the mouthparts of lobsters. FOUND IT:

I wonder if anything is like that in on land crabs or crabs in general :-k

Not just a new species, my friends, but a new phylum. This is fascinating stuff -- I strongly recommend to go read the references.

Doug, thanks for posting this!

That Reinhardt Kristensen likes to rack up the phylums...he did this one also in 1983

I would like to see someone from the micro forum come up with a picture of this animal.

Your welcome Rik. :wink:
