Hibiscus and crabs

Post by Dread »

In honour of my hibiscus blooming last week, here's a shot from when I had more time to admire the process. I wish the flowers would last a little longer, or at least bloom on a Saturday!

And to get back underwater, some crab faces:

In this last shot you can see how much particulate matter can be floating around between lens and subject but still get a reasonable result.

(And this guy is asking us how to do underwater macro? Sheesh!!)

Beautiful images, Ryan. :D Any clue what is that white-dot thing stuck on the crab's antenna, pic #2?

Thanks :) You know I'm always open to learn, and you folks are a talented bunch!

And true to your superb taxanomic skills Rik, the white-dot thing is probably just that... looks to be a complex of shell (possibly Mytilus sp. fragment) and organic debris. I took a look at the original, not anymore telling.

Glad you like 'em!

Thanks again... I'll be 'focussing' a bit more on crustaceans once I have a new underwater system. Most often they stand their ground and are 'easy' to work with. Then there was the 10lb lobster who had no fear... that was a close one!

Ten pound lobster? :shock: It will fear my bowl of melted butter and fresh garlic, plus a garden salad on the side with oil and vinegar of course. :wink: In all actuallity though, the thing would probably be tough as leather. Now for the crabs, where is my shell cracker? Excellent shots of those by the way. I like crabs. :D

Excellent photos Dread. I have an observation on the third picture. I am looking at the fan like (straining) looking appendage in the center of the crabs mouth coming from the right hand side of the mouth. I wonder if that could be some kind of hitchhiking worm living in the mouth or shell of the crab that extends its` food filtering appendage into the mouth area. I know I have seen something like that on the TV or in a magazine. I do not see a pair so I do not think it is part of the crabs mouthparts. What do you think?

You're right that you're not seeing a pair in that picture, I never thought that it might be a parasite (though that certainly wouldn't be uncommon).

However, due to its shape and location, I believe that to be part of the maxilliped, with both the proximal and lateral(out of focus) setae showing.

Here's an anatomical sketch of those parts from a Blue Crab:

Thanks for pointing that out though, I just added some words to my vocabulary!

Well, anatomy is certainly the right place to do that! I was poking around that url you gave, and found this description of a critter that I thought I was pretty familiar with. Ha! Ha-ha! Hahahahahahaha!!! (...trailing off maniacally...) :lol:

Don't feel bad Rik, I'm sure you're not the only one who can't tell the pronotum from the surenal plate!
