1. Both are large and super gluey. At my miniature balcony, I turn around to water other plants only to be smeared with their digestive juices all over the arms. The watering can also gets coated with slime if it is used to water any other CPs near these fellows.
2. Both look VERY alike at the first glance and when they are younger. Until I got armed with the MAGNUM OPUS recently, I was staring hard at the tentacles and the different sizes in dew drops. Now, it's much easier to tell them apart.
The two plants are growing in the same pot. Guess which is which.
