Orbleaf split from its ancestor. As a juvenile, it resembles its ancestor in many ways, albeit with shorter baits, a bundle of baits at its center, and less mat-forming habits, but as an adult it undergoes a dramatic transformation. It begins to fill with a dense jelly-like fluid, which in turn causes it to sink and reach the ocean floor. There, it continues to inflate until it has become spherical, its tough upper surface folding inwards while its softer bait-covered underside becomes its dominant exterior. Modified baits, the bundle seen in juveniles, anchor it to the ocean floor, and there it sits, long filter baits sticking out in all directions to catch as much food as possible.

The Orbleaf has developed sexual reproduction. Its upper surface, folded inwards as an adult, is repurposed as a naturally-protected reproductive organ. With help from muscular contractions, haploid waterborne spore cells pour out of its top, eventually meeting other spores to be fertilized at which point they develop into new juveniles.

Though it looks like a juicy snack at a glance, the orbleaf reduces risk of predation by simply not being very good to eat. Its body is mostly jelly with no nutritional value. When predators do nibble at its baits, which are among the most nutritious parts of its body, they simply grow back. Like its ancestor, it catches microscopic food with its filter-baits and digests it inside its cells.
