African Tigerfish swallow birds in mid-air

African Tigerfish swallow birds in mid-air

A number of news sources have picked up a story about the African Tigerfish swallowing swallows in mid-air (pardon the pun). This post shows the original video as uploaded by the researchers.  The original research paper can be found at this link to the Journal of Fish Biology. The video was captured at Schroda Dam, near Limpopo, South Africa.

From the video, you can actually see fish jumping from the water in attempt to grab the birds.  Sometimes they’re not successful, but other times they are right on the mark.   How cool is that! Ecology in action…  Discovering new things all of the time.  Science is cool!

Life Aquatic Kayak – a submarine kayak

Life Aquatic Kayak – a submarine kayak

The Subo kayak can be paddled on a lake, calm oceanic bay, or slow moving river, but when you get tired of watching birds, moose, sea otters or turtles, you can batten down the hatch.  Time to fill the ballasts as a kayak transformed into a personal submarine kayak propelled via a fishtail – like propulsion device straight from Life Aquatic. Now you can check out the fish, kelp, crabs, and shrimp. According to comments by the creator,  Olivier Feuillette, on Youtube, it has air tanks, a CO2 filter (for extended dives up to 2 or 3 hours), and pressure equalization.  I’ve got many more questions than answers, but until I find the time to build an amazing personal watercraft like this for myself, I’ll just have to admire this video.  Check it out and let me know what you think about the Subo submarine kayak.
