[Delphinus]

Clam spawns will happen on occasion. You have to be careful because one can usually set off a number of them and then you have a small problem on your hands.

Dark and chunky expellate (is that a word? You know what I mean) may just be expelling zooxanthellae. This also happens from time to time. Spring cleaning, in a manner of speaking, I suppose.
