It turns out that the coral reef fish genus known as the wrasse is even more interesting than I realized when I wrote this post about their amazing ability to change sexes when the male leader of a harem dies. I read in this article, that a paper was published this week in the journal Coral Reefs by Giacomo Bernardi, UCSC professor of ecology and evolutionary biology, which included this video of tool use by a wrasse to crush clam shells.
Well, either that or he's just enjoying a solitary game of clam racquetball.
The animal kingdom never ceases to amaze and delight.
