Harpaticoda and some mysterious things

Hello everyone,

Recent I’d been on a trip to Jaigad which is in Konkan region of Maharashta, India. We visited this really famous Shiva temple in the locality known as Karhateshwar it is situated on the edge of the sea on a steep rocky mountain. There were steps to reach down to the sea where the waves were crashing on huge rocks and in these rocks was a stream of fresh water coming from the top of the mountain where a lot of algae had grown. I got some samples of those algae since I’d taken my foldscope along. The featured image shows the location from where I took the samples.

Here’s what  found in the samples

euastrum
Euastrum

This was the first time I saw Euastrum I’d never even heard of it previously.Thanks to google I could identify it. I could film only one video since we were there only for sometime.

I had a tough time trying to identify this one, it’s one of the species of copepod in its adult form belonging to class harpaticoda.

And there were these unusual things.They didn’t move at all but there were many of these. I wonder what they could be..

that’s the fresh water stream I mentioned earlier.

P.S- There was a snake in the crevices of rocks while I collected the samples. Probably a poisonous once since it appeared to be brightly colored. Thanks to him for not appearing and scaring me before I could collect the samples. That was the first time I saw a snake it was amazing 😀 😀

looked back at the pictures to locate the ferns. There they are!

here’s a better picture of the filaments. I’m guessing its Mougeotia. please help me properly id these

🙂  Have fun Foldscoping~

    Hi Mitali,

    Yes, you are right, the desmid is a Euastrum. The harpacticoid is Maraenobiotis or something close to it. I can’t see enough detail in the strands of algal cells to determine their identity.

    Great work!

    Best wishes,
    Janice

    Hi, Mitali! Thanks for sharing your observations in such an interesting post. It is amazing to know about places so far away from where I live! By the way, what beautiful landscape it is!

    Those structures you are asking for identification are sporangia from ferns. You can still see some of the spores inside.

    A pleasure to read you!

    Hi Janice and Christina 🙂
    Thanks for the lovely comments and helping with identifying the fern sporangia. Never knew fern sporangia look so beautiful. 😀 . I’ve updated the post with a pic of the algal strands. Do help me ID them

    Thanks again!

    Hi Mitali,

    The only way to tell for sure if the algal cells are Mougeotia is to use a staining procedure to reveal if its characteristically shaped pyrenoids are present. The procedure is rather involved.
    See http://www.tandfonline.com/doi/abs/10.3109/10520297009067803?journalCode=ibih19

    The cells are not magnified enough or clear enough to see certain structural elements for identification purposes. If you want to see some of the possibilities for algae identifications, see Prescott, G.W. 1970. Algae of the western Great Lakes area, 4th printing, W.C. Brown Co. Publishers, Dubuque, Iowa. The taxonomy and classification is not up to date, not all species are in the book, and the diatom section is useless. However, you will get a sense for the difficulties in identifying taxa from various algal groups.

    Best wishes,
    Janice

    Absolutely loved the post @Mitali.

    The video is incredible. I am surprised to see the leg segments are all in the front, with a region with no leg segments. That’s got to be a hint to identify this creature.

    What a beautiful landscape to see. And the snake, oh my. Please be careful. But maybe you are collecting samples; you even noticed it at the first place. It’s amazing how folds coping makes you hyper aware of your surroundings.

    Keep exploring..

    cheers

    Thanks Janice I’ll try to get an ecopy of the book 🙂
    Thankyou Manu sir.I’m Glad you liked the post 🙂

    @Mitali. Fantastic. Since you visit the coast often, you might consider making a plankton net. It is easily made with readily available material. See a post by @MattRossi
    https://microcosmos.foldscope.com/?p=17431

    This way you will concentrate your sample. The new foldscope kit has a nylon mesh I am told.

    Laks sir, since Ganpati vacations are going on I’m definitely going to try my hands on making a plankton net. Thanks for sharing the link ! Will surely try it out soon!
