A recent study (Grady et al., Science, January 2019) examined
the effect of ambient temperature on the swimming speeds of ocean
dwelling vertebrates. In the figure below, each symbol is a data
point from one species: Solid circles are species of fish; open
circles are dolphins; solid squares are penguins, and open
triangles labeled “Pinn.” are pinnipeds (e.g., seals and sea
lions). Burst speed refers to how quickly an individual can swim in
a straight line over a relatively short distance (like a sudden
sprint when running). Answer the following questions based on this
figure from the paper. Mark A if the statement is True or B if the
statement is False.
Dolphins are more likely to capture fish when water temperatures
are 30oC than when water is 10oC. ( True or False)
