Practice question

Primary mode of propagation and colony expansion in ectoprocts involves asexual budding where daughter zooids bud from parental body wall producing interconnected zoarium of polymorphic zooids specialized for feeding, defense, reproduction and support. Budding generates modular growth optimized for sessile filter feeding maximizing space capture. Sexual reproduction also present producing cyphonautes triangular shelled or coronate non-feeding larvae settling to form ancestrula founding new colony. Freshwater phylactolaemates additionally produce statoblasts as dormant chitinous propagules highly resistant to desiccation, emphasizing prevalence of asexual colony formation and resilience enabling survival in variable environments and dispersal across habitats.
