Understand latitude. latitude measures how a point is north or south of the equator. now understand longitude, longitude measures how far a point is easy or west of the prime meridian. understand how they appear on a map. now, i’m not the best at helping or explaining, so if this doesn’t help... then hopefully someone else answers for you.

I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor.

Hope this helps.
