Methods of detection by creatures and species

[Forceally]

I know that in the Star Wars universe and RPG, we have creatures and species who have greater vision than humans or have means of detecting others that humans don't have. For example, the Gands can see in the ultraviolet spectrum. And some creatures and species have darkvision - allowing them to see normally in low-light conditions. Do we have any creatures or alien species who have any of the following means of detection:

Echolocation - I think this is akin to the bats' sonar and how they use it to navigate and locate prey.

Thermal vision - being able to see body heat by wearing heat-vision goggles or how the Predator primarily tracks his prey in the first two Predator movies. This is definitely not low-light vision. While I think some creatures have special organs to sense heat, I don't think being able to see in the infrared spectrum naturally has ever been mentioned.

I was going to ask about tremor sense - like how Toph Beifong is able to use earthbending to see in Avatar: The Last Airbender and how the graboids in the Tremor movie series can track their prey - but I just remember those worm creatures on Blenjeel from the Jedi Knight: Jedi Academy computer game try to track Jaden Korr the same way the graboids do.

Google and Wookieepedia are your friends.

Back in the late 90s, i did (after seeing tremors), make up a beast, that did both echo location AND tremor sense, but the game i made them for, never happened.. Unfortunatley the notes for that game got lost on the move from bahrain..

Electrolocation: detecting something by the electrical field its body generates.

And of course the force as well for sensing -

from the Miraluka to other non-jedi force users, and other creatures that I am too lazy to to look up.

(in my game I call them latent force users - who have the sense skill, and with it a limited force based perception).

I was curious because I was thinking about creating Force powers for my work The Force Compendium that would grant a Jedi the ability to detect other individuals or creatures via echolocation or tremor sense. Being able to see in the infrared or ultraviolet - that's using shift sense.

Obviously, this would be redundant for those species who have these methods of detection naturally.

I was watching an anime where a protagonist was using the abilities I mentioned to sense what's ahead of him and his friend, and I thought, "Wouldn't it be cool if a human Jedi could use a Force power that would grant him echolocation or tremor sense?" So that's why I created this thread.

How's about make an upgrade to 'shift senses', that gives them either echo location, tremor sense, Or electro-sense, Pre-req IS shift senses...

Say Sense power
Moderate base diff.
If you get +8 over, you gain 2 of those above senses
+16 over is all 3?

Echo Location as used by whales, Dolphins, and certain other creatures could fall under the existing Shift Sense power as it involves altered hearing (though the noise emission might require control to alter the vocal chords). For other, more obscure methods of detection:
