Wait, what? What organisms depend on a magnetic field to find the surface?
- mensetmanusman 6y agoNot only the surface; here is one among many describing the magnetotactic sense. https://www.sciencedaily.com/releases/2020/09/200914112224.htm https://www.sciencedaily.com/releases/2020/09/200914112224.h...
- pklausler 6y agoI understand the usefulness of sensing the magnetic field to navigate north/south/east/west; what I find hard to believe is a need to use the magnetic field to navigate up/down.
- mensetmanusman 6y agoMagneto-aerotaxis can be used to help some organisms find correct oxygen concentrations apparently(field gradients): https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4104051/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4104051/
