Hydras! 20x magnification. Darkfield. Speed 800%. 🔈

to all the microscope enthusiasts: always have a couple tubes on you for spontaneous sample collection. Yesterday, I saw a little pond (more of a giant puddle) on the side of the road that looked scummy and green so I whipped out a couple of 50mL centrifuge tubes from my purse and scooped up some water. When I got home, I took a look and noticed *literally* over 100 hydras in one of the tubes. Jackpot! I’ve never seen so many at once! I put a bunch of them on a slide and started recording and turned up the contrast really high to get the black and white effect. Stay tuned to find out what color they are as I will be recording them in darkfield next!
Here’s some background info on hydras (also correct to say hydrae): Hydra is a genus of freshwater cnidarian (class Hydrozoa). Other cnidarians include jellyfish, corals, anemones, siphonophores, and many more. Hydras are radially symmetrical and have two tissue layers in their body. They also have a nerve net (simple version of a nervous system) and their tentacles have cells called cnidocytes that secrete stinging chemicals used to stun their prey. Hydras reproduce asexually by budding which you can see in some of the individuals in this series of posts. Budding is when an identical hydra grows out of the parent and will detach when it is mature enough to live and reproduce on its own. Many scientists are interested in hydras because they don’t really age and will continue living until eaten or exposed to deadly conditions and they can quickly and efficiently regenerate damaged tissue. Learning the mechanisms behind those processes would be really interesting and potentially helpful in the future to understand the process of mammalian aging and in biomedical applications of wound healing and tissue regeneration.
