The word "trough" in the common name refers to the fact that all Mactra shells have a large ligamental pit at the hinge line, which in life contains a large internal ligament. Most bivalves in other families have an external ligament instead.

gollark: "You want to get to your neighbour's house? You have to loop around the entire city on dirt paths, pay $1000 in tolls, and spend 5 hours in traffic jams."
gollark: I should play again and design the worst road network possible.
gollark: Ah, cool!
gollark: Or funnel everyone exiting down a massive series of dirt-path loops with toll booths.
gollark: What if... you disconnect all the ways to leave the city, but have really fast input?
