Sea Monkeys

ok, not really but this video sure reminds me of them.

“Most mayflies lay their eggs immediately after mating; the eggs then take anywhere from 10 days to many months to hatch. Cloeon cognatum is an exception. This species is ovoviviparous, which means that a mated female holds her eggs internally until embryonic development is complete (about 18 days), after which she lays them in water and they hatch immediately. This female was dropped onto the water surface moments before the video started.”

  1. Wow… and all this from one Mayfly.! The wonders of nature … Thanks for sharing.

  2. Great Video Mark what is the distrubution of this species I seached the web but did not find an exact answer, I belive they are not found in the UK do you know which is the nearest country for this species, it must be a real turn on for the fish when these hatch below the surface, it would be interesting to know if surface feeding fish or feeding below the surface, which becomes the greater draw to the fish.

  3. ok Pete. it’s just that cognatum is referenced in the synonym section of the link i shared.
    “Cloeon cognatum Stephens, 1835”
