Marine amoebae live in a saltwater environment. If the vacuoles take in too much salt, it'll suck all the liquidy stuff out of the amoeba itself. Freshwater amoebae are in a freshwater environment so they don't have to worry about that.

Marine turtles typically live in saltwater environments, while freshwater turtles live in freshwater habitats. Marine turtles have flippers adapted for swimming long distances in the ocean, while freshwater turtles tend to have webbed feet for navigating in ponds, rivers, and lakes. Behaviorally, marine turtles migrate long distances between feeding and nesting grounds, while freshwater turtles are more sedentary in their habits.
Because the surrounding freshwater concentration is higher than the salt concentration inside and so all the water from the vacuoles has left because of osomosis. while the marine amoeba has the surrounding salt concentration equal to the concentration inside the vacuole.
