Sharks — as meteorologists? Say it isn’t so! Sharks can in fact do a rudimentary form of forecasting, using a biological system that allows them to sense changes in pressure that often come before significant weather events like hurricanes. A Georgia Aquarium aquarist explains how this is possible.

Evidence indicates that sharks, particularly larger species like great whites, are capable of detecting incoming weather events. Tagged sharks have been observed moving to deeper waters ahead of storms, suggesting they can sense changes in atmospheric conditions. 

This ability is attributed to the sharks' lateral line system, a sensory organ that detects pressure and vibration changes in the water. While meteorologists rely on technology such as satellites, sharks use their natural adaptations to forecast weather changes, sometimes with impressive accuracy.

New aquatic competitor enters the 'best forecast' ring

Apparently we're not just competing against other meteorologists for the best forecast. We're also competing against sharks. So there has been some evidence that sharks can sense incoming weather events. Some of the larger tagged sharks like great whites, they have seen them kind of move to deeper waters when there is a storm coming. So basically sharks are just like us, predicting future atmospheric conditions based on current atmospheric conditions, except maybe they do it just a little bit better depending on, you know, whether or not they have satellites. They can actually pick up pressure changes, mostly using a system called the lateral line system that lines the sides of their body. They have all these pores connected to a canal that will actually pick up pressure and vibration. But I don't need to worry about these sharks because they're in a controlled environment, controlled weather, controlled climate. Plus they're my friends, so they wouldn't come for my job.
