What's the difference between sushi and sashimi?

Going to a sushi bar for lunch today, would be good to know the difference! :)

Lunch was excellent, I had the ebi, kane, and spicy tuna sushi and a california roll.

Sushi refers to the word "rice", but it is typically refered to as finger-size piece of raw fish or shellfish wrapped in roasted seaweed and vinegared rice. in the U.S., it also is referred to other ingredient(s) wrapped in roasted seaweed and vinegared rice.
examples:
California rolls - ingredients: fake crab meat, avocado, and cucumber
Tekka rolls - ingredient: raw tuna

Sashimi is raw fish slices without the rice. it has evolved to the inclusion of shellfish, fish roes, and other food items.
examples:
Sake - raw salmon slices
Maguro - raw tuna slices (can be yellowfin or blue fin)
Toro - raw fatty blue fin tuna slices
Hamachi - raw yellowtail slices (not to be confused with yellowfin)

Both are delicious. enjoy your adventure
