Default Rainbows vs. Steelheads

Been wondering for a while what the difference is between the two, since I've read scientists aren't sure and they appear to be genetically identical.

Came across this tonight, makes for an interesting read:

Apparently, it seems like based on their environment growing up they may end up a Steelhead or a regular Rainbow. Neat stuff.

An interesting read for sure.
I never gave it much thought, I just thought that steelhead migrated upstream and spawned. But if you think about it, salmon die after spawning but steelhead don't...

Genetically they are the same Trout. The only difference is the Steelhead spends much of it's life in saltwater vs. the Rainbow. If the Steelhead can't make it to the ocean, it is considered a Rainbow. Of course there are minor differences in body shape and anatomy due to generations of expending more energy in the ocean and spawning upstream. But, in general they are the same fish...

It's fascinating how they can adapt to their environment to this extent. Are there any more examples of this in nature?

Yes, I moved to a rural area after living my whole life in or near Chicago. I have adapted quite well - lol!

I'm sure there are many examples in nature. Nature finds a way. Dolphins off the cost of Florida hunt in a certain matter where they confuse fish by circling and digging their noses in the mud. This is a learned activity that must get passed down from generation to generation b/c they are the only known dolphins to hunt using this method. Maybw not a direct correlation to the question, but pretty darn cool nonetheless!

Specks, reds, and flounder are salt water fish but are able to be farm raised in fresh water.

Similar story with Orcas. There's 1 pod of orcas which figured out how to hunt Great Whites, and they teach it to the young. They grab a fin of a shark that's small enough to bully (maybe a measly 11 feet, lol), and hold it upside-down until it dies. (Sharks have a thing where they are paralyzed when they are upside-down I guess) Then they rip it apart and eat its huge, fatty liver.

Fish aren't humans. They don't need comfort crawdads to help them get thru stressful situations.

Tonic Immobility I think it's called (Yeah I watch a lot of Planet Earth - lol!) NOT to be confused with the human version "Vodka Tonic Immobility" lol!

Sorry about the multiple post thing - don't know how to quote others from separate posts in my post w/o getting rats nested - lol! Ahhh, at least it looks like more activity on this site - eh?

Paul, nor do fish need emotional support peacocks to travel through airports!
