Bugula neritina

Bugula neritina (commonly known as brown bryozoan or common bugula) is a cryptic species complex of sessile marine animal in the genus "Bugula".
It is invasive with a cosmopolitan distribution.
"Bugula neritina" is of interest from a drug discovery perspective because its bacterial symbiont, "Candidatus" Endobugula sertula, produces the bryostatins, a group of around twenty bioactive natural products. The bryostatins are under investigation for their therapeutic potential directed at cancer immunotherapy, treatment of Alzheimer's disease, and HIV/AIDS eradication, due to their low toxicity and antineoplastic activity. 
The draft whole genome of "Bugula neritina" has recently been sequenced. This adds to the growing number of genomes on the total list of sequenced animal genomes.
"Bugula neritina" is also of interest in materials science, where it is used as a model organism in biofouling studies.
