Sonja and her husband René started diving in 2003. After diving the coral reefs of Thailand, Malaysia and the Maldives, they moved to the Philippines for professional reasons for 4 years where they discovered the incredible wealth and variety of the macro underwater world. And who says macro in the Philippines says the butterflies of the sea: nudibranchs. In order to be able to identify after the dive the nudis they saw, Sonja started photographing them. This developed into an interesting cooperation between her and her husband where he is the spotter and she makes the pictures after which they both try to identify the critters. After about 500 dives of which well over 300 in nudi capitals like Anilao & Dauin they now have a personal collection of about 150 different species of nudis + lots of other macro critters. The challenge for them being to discover more new species for their collection. Unfortunately work definitely interferes with diving!
