Its really hard to match plankton with manuals. Because photo of manual are saturated and full of high contrast.
If you have identified sample from laboratory, then please help me out by sending your identified samples to
Really appreciate your suggestion Malcolm Baptie
. I uploaded 5 photographs with numbering on top left corner. Number 1 and 2 photos are the same species view from different angel. Please check this out...
Thank you Malcolm Baptie
for your kind support. Its really helpful and informative. It does matter my research a lot.Here, I attached more 13 photographs (No. 6-18) which didn't identified yet.
If possible, please check those photos...
I will ignore those detritus.
Such a response spreads altruism worldwide. Thanks @Malcolm Baptie ....
22 might be an immature zooplankton. In real ocular view, It looks like a zooplankton. But, in photograph its not like that though.
By the way, thanks again.
No problem at all...
Another question to know...
Should I categorize plankton species by species or groups of plankton? What is the standard scientific method?
As your long time experience, its easier to identify plankton. But as a novice, its really time consuming. I would go for your valuable suggestions ...
That is the real scenario you mentioned at the end. I captured a lot ( about 1300 photographs) where species, species organ, detritus, undefinable materials are present.
Hi Mohammed Anas Chowdhury , Based on by observation most of the sample are detritus materials, you should try centrifugation as a method to isolate plankton samples take 10 ml of your sample then centrifuge it, decant the supernatant and at least leave 1 ml of sample.
For the identification, #10 is somehow a calanoid sa mention by Malcolm Baptie
but you should dissect it to know what the genus and species. For #20, i do not not believe its a diatom its probably a shadow of the lens as you can see there is a detritus material in the middle. Probably im mistaken but a coscinodiscus has costae, spines, rimoportulae, fultoportulae which is not visible in LM.I would suggest that you should try identifying the plankton samples upto species level its a good training and if your going to publish it. Read books on plankton taxonomy and you also try to draw for phytoplankton and zooplankton. There are taxonomy books that are free online. I know it will be hard at first but practice makes perfect. I know im no expert im just here to help but with proper practice you can identify plankton samples.
Thanks @Lawrence Vitug for your valuable suggestions. I will check all the procedure you mentioned.
For #20, I checked that sample very carefully. That was not a shadow for sure. May be its not a plankton, may be part of any plant or seaweed or detritus.
Moreover, I will consider your suggestions about taxonomic study....
Hello, Malcolm Baptie
and Lawrence VitugHow to know a plankton is new to science and how to claim it as new species?
Manuals are important but not sufficient. You need to study a lot under the microscope and you need to read a lot of papers!
