here's a question to get some non-spam action going!

I went out for tempura yesterday, and the pair seated next to me had
some kind of spiny tempura. It looked a little like

this spiny crab, but not quite. Actually, it reminded me of a spider
with an exoskeleton. When the chef explained what it was, I thought
he used the word "ebi" in its name, and "ebi" usually means shrimp,
but sometimes can refer to small lobster-like crustaceans (like Ise-
ebi).

Any idea what they were eating? I think they were eating the most
expensive meal (more than $100 for lunch!), so it must have been
expensive, which also makes me think it must not have been something
terribly common. It looked so good and crispy, I might have to order
it a la carte next time!
