A genus of freshwater red algae that forms jelly-like, frog-egg-like clumps in streams and rivers.
From Greek 'batrachos' (frog) + 'sperma' (seed/sperm). Named for its resemblance to frog eggs in appearance and gelatinous texture.
If you've ever seen weird jelly-like blobs in a stream, you might've spotted batrachospermum—it looks exactly like frog spawn, which is why scientists named it that way!
