In my country thats called "sopa marinera" but ours got a bigger variety of seafood such as:
Choritos (Mytilus Chilenis)
Almejas (Chilean Littleneck - Venus Antiqua)
Jaiba (Cancer spp)
Congrio dorado (Genypterus blacodes)
Ostion (Argopecten purpuratus)
Gambas (Parapenaeus longirostris)
Thats the base, but some people might add more seafood, pretty good during winter, the soup is killer! Like, you eat this + white wine and you go to sleep like a baby
