Diving with Sharks @ L'Aquarium de Barcelona

My second dive in l'Aquarium de Barcelona - an incredible experience again. You gotta love it.
The aquarium features 300(!) different species in a 3,700 m3 tank. Gilt heads, moray eels, morays, very nosy ocean sunfish and rays ....and different types of sharks, including those 3 beauties:
Bull shark: 3,5 m in length and statistically the third most dangerous to people (still, half the chance of a fatal lighting strike)
Shortfin Makos: almost 3m in length with burst speeds:up to 80km/h / 50mp/h
Sandtiger sharks: around 3 m with two?! uteruses (only the strong one survives,wicked)
...and lots a shark teeth on the floor to collect ^^
N-joy!
