It’s been a month since I’ve last blogged. I got a bit caught up in the holidays, and I’m admittedly still very much in a holiday mood, but the real world is drawing me closer. I hope to return to some regularly scheduled posting soon.
This week, an article by the National Geographic titled “How Do Sea Turtles Find the Beach Where they Were Born?” has been trending online. I’ve always been amazed by the fact that despite the extensive migrations made by sea turtles, they manage to return to the exact same place in which they were hatched to mate and nest. As it turns out, scientists have now found that loggerhead sea turtles (Caretta caretta) return to these initial beaches by sensing Earth’s magnetic field. Apparently, each beach has its own “magnetic code”. Accordingly, however, nesting sites will shift in response to changes in this field.
An internal compass is certainly a handy navigational tool, sometimes I wish that I had one.
