For me nudibranchs-hunting is like collecting stamps..You always want to find new ones for your private collection. This is Thuridilla multimarginata (really very small) photographed in the Aquarium dive site of Havelock Island_Andamans-India_2023

A large chunk of coral life is tiny, lesser known, easily hidden creatures. These include both sessile (fixed in one place) and mobile reef invertebrates, as well as the itty bitty reef fish like this in the photo_2023

A squat shrimp often called sexy shrimp because of its provocative dance. Their quirky abdominal movements, often in sync with one another, are amusing to observe and can captivate divers for long underwater time!

A still goby looking at me with curiosity. The gobies usually stay within their territory in the rock but will go out and explore occasionally as in this photo taken at the Aquarium dive site _Havelock island_India_2023

Photograph nudis in these parts of Arabic Sea is a bit more challenging than elsewhere given the poor visibility.
