Shark!!

oooook, fessing up, this is not Hong Kong, tho they have been recorded in HK waters....this is of course a lovely whale shark.

yep, its a fish and a shark....in fact it eats krill, and is a filter-feeding carpet shark.

And I am trying a new underwater housing for my camera....

It is the biggest fish in the world. The largest confirmed individual had a length of 18.8 m.

they have unique patterns to ID them.

It is by far the largest living nonmammalian vertebrate.
