This clam is critically endangered. During my visit to Coron, I discovered that it's not something to be eaten, highlighting the importance of protecting such precious marine life.
I never thought clams could be this huge. I thought cartoons like Tom & Jerry and Looney Tunes were overexaggerating with the big clams in the Ocean/Beach themed episodes.
This used to be available in the us very infrequently at sushi restaurants and yes they are normally much smaller from what i understand about the same size as a conch, bear in mind i have only seen this once or twice over 15 years ago
