Final answer:
Fish Species 2 would most likely be found in a shallow freshwater environment due to its preference for low salinity.
Step-by-step explanation:
Fish Species 2 would most likely be found in a shallow freshwater environment due to its preference for low salinity. Unlike saltwater fish, which have specialized mechanisms to excrete excess salt and survive in a hypertonic marine environment, freshwater fish have adaptations to cope with a hypotonic environment. They tend to take up water from their environment and pass a lot of dilute urine to maintain electrolyte balance.
