Animals extra senses:...huh

How did animals in Thailand know the tsunami was coming?

I heard that some electric eels actually detect prey (or predators?) by sensing how the electric field they generate is effect by the presence of the other animals body.

This could be BS.

I don't think that animals necessarily have "extra" senses, perhaps they are more in tune with certain sense instinctively than others, but I don't think it's necessarily "extra" senses, rather "more in tuned", "stronger" perhaps?

I've been through many hurricanes in my hometown of NW Florida. There is always a period where you play the "sit and wait" game - it could look like it's coming straight for you, but then turn away at the last minute. Then again, it could look like it was heading east or west of you, then BAM! It turns and hits us directly. One thing I noticed since Hurricane Camille in the late 1960's was the activity of the frogs. They are everywhere and croaking like crazy before a hurricane hits us. My batting average has been dead on since paying attention to the frogs.

Watch the rats, the rats know when disaster is coming.

While I do believe that people and non-human animals can 'sense' ambient atmospheric pressure (aiding in the prediction of storms, etc), I'm not sure that this is an 'extra' sense. I mean, it seems to me like we could do this using the same kinds of sensory nerves we use to tell how heave something is when we pick it up.


Sensing and interpreting 'electric fields' does strike me as an 'extra sense' that some animals have:


E. Electroreception.

1. Some bony fishes in the families Electrophoridae, Gymnotidae, and Mormyridae produce a low-voltage electric current that sets up a field around the fish. Electric organs are made up of cells called electrocytes that have evolved from muscle cells. Electrocytes typically are thin and stacked on top of one another.

Skin organs on the electric eel (Electrophorus electricus) detect disruptions in the electric field.


2. Tiny skin organs on the fish detect disruptions in the electric field that are caused by prey or inanimate objects. Thus, electroreception is an adaptation for detecting prey and for navigating in murky water.

3. Other fishes produce stronger electric currents for stunning prey


I find this amazing!
