At Lankayan you don't even have to get on the boat to see rare sea life: these pictures were taken right under the jetty!
When we were getting ready for the first dive of that day, our guide Semion suddenly began fishing some seaweed out of the water. He searched through it for a little while and then showed us seven (7!) Saragossa Frogfish in all sizes from 4mm up to 7 cm!

First we took some pictures of this rare and hard-to-find fish, then we went on the boat and went diving at a spot called "Jawfish Lair".
