krystalltyllskinn
Scytinostromella heterogenea
Krystalltyllskinn (Scytinostromella heterogenea) is a distinctive marine bryozoan characterized by its translucent, crystalline-like colonial structure that forms delicate branching patterns on rocky substrates. The species displays remarkable morphological variation across its range, with colonies exhibiting different growth forms and zooid arrangements that give it its 'heterogenea' designation.

Species Profile
Krystalltyllskinn (Scytinostromella heterogenea) is a distinctive marine bryozoan characterized by its translucent, crystalline-like colonial structure that forms delicate branching patterns on rocky substrates. The species displays remarkable morphological variation across its range, with colonies exhibiting different growth forms and zooid arrangements that give it its 'heterogenea' designation. As a filter-feeder, it plays a crucial role in marine ecosystems by processing plankton and contributing to benthic community structure.
The species faces severe pressure from ocean acidification, which compromises its ability to maintain its calcium carbonate skeletal structure essential for colony integrity. Coastal development and increased sedimentation from terrestrial runoff are degrading the clear, low-turbidity waters this species requires for optimal feeding and growth.
Key Facts
Habitat & Distribution
Krystalltyllskinn inhabits shallow subtidal rocky reefs and kelp forest understories at depths of 5-25 meters, where it colonizes vertical rock faces and the bases of large algae. The species requires areas with moderate to strong water flow and minimal sedimentation, typically found along exposed coastlines with high water clarity.
Threats
