shrimp IDs

[strung_0ut]

Anyone know what kind've shrimps these are? The first two were said to be tiger shrimps. The name I can see makes perfect sense, but there is already a shrimp labled tiger. And the 3rd one was said to be bumble bee, it looks like a crystal red but I'm almost 100% sure its not, its more orange then red of anything. My guess is that these are hybrids.

The pictures are too small for me to see

Hi Dennis,
your pictures are a bit too small, can you please post new ones? On these tiny pictures they look like bee (in S'pore diamond) shrimps. The last picture is too small to see some details. But it also looks like a bee or bee x? hybrid.

regards

Robert

I have edited the images link so that it will display the full picture.

Dennis, in future if you want to show the full picture, remove the .thumb from the url of the picture, otherwise it will just show the thumbnail version. Alternatively, use this format - [img]Thumbnail pic url[/img] - for a clickable version of the thumbnail.

Hi all,

Dennis, I think your shrimps are bee shrimps. Just have a look there and compare:

I would hasten to advise that shrimps are in general very difficult to identify to a specific species without dissection. The pics posted show members of Caridina or allied species. Coloration and body patterns are not definitive traits, rather the details of the legs/claws and rostrum are, and these requires dissection and very strong magnification.

I recently visited the shrimp group in NUS (their lab is just directly above Prof Benito's) and spoken to Cai Yi-Xiong (Caridina expert) and Daisy Wowor (Macrobrachium expert). Listening to them, and reading Vol 36 of Fauna Sinica (courtesy MrTree), I have come to the same conclusion as MrTree, no more scientific names on my shrimp pics

choy,
did you hear anything about Caridinia japonica being misnamed..... the Amano shrimp should be C. multidentata or something instead....

yes, paper has been submitted but not yet published. Caridina japonica is a junior synonym of C. multidentata.

YX Cai says this has been discussed with the japanese researchers and they accept the facts.

teck song, there are a good number of shrimp species looking similar in coloration and pattern to the so-called bee shrimp. don't bet on their ID base on patterns and colours. there are 130 species of Caridina and allies in China alone.

I quote from Fauna Sinica - Invertebrata Vol 36 - Crustacea - Decapoda - Atyidae, pg 77 *apologies for my poor translation*:

Neocaridina denticulata (de Haan), N. heteropoda Liang, and N. palmata (Shen), all used to be classified as Caridina denticulata de Haan, and are very common species in the East Asian region.

All three have strong resemblance in morphology, while populations from various localities have significant and complex variations in form due to environmental factors. Traits such as length of rostrum, variation in rostral indentations, etc all cannot be reliable indicator for identification.

haha, choy. i know u will be back fast.

I know what u mean, but to simplifies common name to local folk.
