Little marine biologist found some more gastropods (again), he was quite happy with the find as he claims some of these like the 'Heliconoides inflatus' should be found in the deeper waters only, or mostly. So he was lucky to stumble on a plankton 'swarm' in the shallow water near our house. I think he said something about 'upwelling'... There isn't much footage of these on the internet, so I feel these are a nice find. Particulary Heliconoides was in an especially good mood for acting.
Me and my wife played the music if that is of any interest (I like my new analogue synth toy, so we played around a bit

)
Gear is: Olympus BH-2 BHS, NFK 2.5 with Sony A7S II and DPlan 4x and 10x.
I'll make this public tomorrow after he checks all the facts in the description, so here is the microbehunter.com forum exclusive premiere
I hope you enjoy...
