Ecology

This species has been found around the world in coastal habitats.[2]

Like other Lophophorata, P. harmeli is a filter feeder. They have been known to various bacteria and other planktonic organisms with a size range of 1.2–12 μm.[4]

Development

Larvae have a minor nerve ring.[5] During larval development, serotonin-like immunoreactive parts of the nervous system change.[5]
