You can often see huge bunches of crinoids sitting on rocks or coral or some other kind of perch.
They sit and taking advantage of water currents as they flow by... Often there are many. Sort of like if you have good cell phone reception.....
But did you know that crinoids actually have what's called "site fidelity"? That means that they will remain on a single perch for a long time!
So how long?
- Some are known to stay in the same place for up to TWO years!!!
- One account actually reported a crinoid that stayed in the same "residence" for FIVE years!!
- Some observations series have continued for over SIX MONTHS with no apparent change!
But apparently, there IS competition among individuals for a specific perch with a "winner" forcing the "loser" from the most ideal perch.
So, what have we learned? Crinoids apparently stay in a SINGLE place and they will work to stay there.
Wow. Who'd a thot something so innocuous what have so much depth?
