Answer:

Its conclusion is flawed because in a scientific investigation it is necessary to carry out the experimentation in a significant sample of hermit crabs. In this case Laurita and Trey only considered 2 crabs whose behavior may be determined by other factors, so it is necessary to increase the study sample .

A subset of the population is called a "sample," and therefore must be representative of it. In general, when a sample is estimated, the population size must be taken into consideration.  Very large populations will require large samples for their representativeness, and small populations will require smaller samples.
