It says that fish use the TMAO protein to protect themselves from pressure. But other organisms use a combination of multiple proteins and that apparently lets them survive higher pressures.
So it seems the fish would basically need to re-evolve how to handle pressure, but in a different way, to be able to go deeper.
- flangola7 4y agoIf they're born and live at that depth isn't the pressure equalized inside and outside of them?
- undersuit 4y agoTemperature and pressure are very related. Fish that live at 8400 meters are dealing with pressures/temperatures/energies that need additional attention. The biological processes of fish start failing at the pressures of 8500 meters or whatever, doesn't matter if the fish has the same internal and external pressure, the pressure has impeded the effect of some protein.
- refurb 4y agoIt would be, but chemistry changes with pressure. So while there may not he mechanical stress on the fish, their proteins may not function correctly at high pressure.
