After Prof. Senn attended constantly to the plankton with its field courses during the last years, also the students from Basel with Mr. Dr. Erhardt, which were staying in Tarifa for a week, got the opportunity to have a look at this hidden, miniscule organisms with their microscopes.

You can see on the pictures how one of our biologists lifts the catch with a special plankton net.

Different organisms of plankton: (from the left to the right) a Cyclops, a Dinoflagellata belonging to the herbal plankton, a Pteropoda. -casi-

We supposed during the last days, that the sperm whales will abandon slowly. However today we saw seven individuals of this huge animal on one of our trips

But that is not enough: A school of pilot whales accompanied our boat, showed various jumps and even swam for a while under our boat.

Mr. Dr. Andreas Erhardt who was on a trip with some scholars of the gymnasium Bäumlihof Basel / Switzerland has been one of the happy ones on the boat seeing orcas for the first time this summer. We were searching the sperm whales when suddenly the sword of the big male orca, which we know from last year, emerged from the waves. Shouting and cheering on the boat: The orcas were there!
A family of four: male, mother with a little calf and either another young male or a little female! -KH-
