Anytime!!!
Anyway...I didn't know that new research had uncovered the rostral pit in Aspidites! That is very cool to know. It is like you pointed out, if you watch them forage, hunt, discover food, you will see a certain reaction out of them.
I am "thankful" to be involved in a hobby where research, observation and attention to detail never ends! My "hat is off" to the researchers!!
