I received fresh seed from a friend and sowed them within four days of collection. To my delight they were up in only 14 days and upon closer inspection today (27 days later) I noticed that in addition to the tiny first leaf was a bladder the size of the leaf itself. Looks like this guy is wasting no time looking to catch his first meal!
Photo below is of the seedlings with the blue bar representing three quarters of an inch. Arrow is pointing to bladder.

Congratulations! You're a father!
Very cool. I'll be getting my first Utric next week and you've officially made me excited!
