The #BostonMarathon is almost here, and while we can't exactly lace up fins for our fish friends, we do have some incredible long-distance swimmers in our tanks!
Here's what makes them marathon material:
Hydrodynamic Body: Their sleek, elongated bodies slice through water with minimal resistance, conserving energy for the long haul.
Powerful Propulsion System: Their muscular tails act like built-in engines, propelling them forward over vast distances.
Fuel-Efficient Fins: They have small, rigid fins. These streamlined fins reduce drag and allow for smooth, energy-saving movement.
