Or, shields up!

The essence being that you don't have to be invisible to be stealthy,
you just have to look like the surroundings. IOW, camo.

The "look like your surroundings" trick is (relatively) easy to do
when you're a cuttlefish, in an environment filled with pebbles and
other debris to mimic. If you're a stealth aircraft or (saints
preserve us!) spacecraft, in an environment filled with...nothing, I
would imagine this approach is a bit more difficult.

SNIP:
You don't really need camo in nature. Just sit with your back against
a tree and don't move. To be really stealthy, wear a net face covering
or dark sunglasses so the critters can't see your eyes. They will
repeat will alert to eyeball motion. Takes a fair amount of self
discipline not to move, but you'd be surprised how close the wildlife
will come to you if you sit very still. Note - the tree wil help you
remain still.
