Phoronopsis harmeri explained

Phoronopsis harmeri is a species of marine horseshoe worm in the phylum Phoronida.^{[1] [2]} It was first described by H.L.M. Pixell in 1912, and was found off of Vancouver Island.^[1]

Ecology

This species has been found around the world in coastal habitats.^[1]

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.^[3]

Development

Larvae have a minor nerve ring. During larval development, serotonin-like immunoreactive parts of the nervous system change.^[4]
