Spotted a worm using the same technique as the snail, i.e using a secreted strand as a rope to travel vertically. But the worm was going up! Not sure how the strand came about, as I’ll find it hard to imagine the worm being capable of somehow creating / shooting a 12 feet long vertical strand working against gravity. Can only assume the worm found a strand abandoned by a snail, and decided to see where it went.
Captured a video since the worm is quite faster than snails are, and can be seen inching its way up.
