Lace Bryozoan

Reteporellina denticulata

Reteporellina denticulata, commonly known as the Lace Bryozoan, is a sessile organism found primarily in tropical waters. This species typically inhabits the Eastern Central Pacific, with recorded occurrences in Costa Rica. It is often found at depths shallower than 40 meters, with the majority of sightings occurring under 20 meters. The Lace Bryozoan forms colonies that can be identified by their lace-like appearance, which sets them apart from other bryozoans that may have more solid or less intricate structures. Their unique morphology allows divers to recognize them easily among various marine life. As a filter feeder, the Lace Bryozoan consumes plankton and other small particles suspended in the water. It plays a role in the ecosystem by contributing to the food web, providing a habitat for small invertebrates. The Lace Bryozoan is hermaphroditic, meaning that individuals possess both male and female reproductive organs. Fertilization and egg brooding can occur either internally or externally, allowing for flexibility in its reproductive strategies. Encounters with the Lace Bryozoan during dives can be intriguing, as divers may observe these delicate structures clinging to rocks or other substrates. They are harmless to humans and do not pose any threats. Although the conservation status of this species has not been evaluated by the IUCN, it is important for divers to appreciate and protect the delicate ecosystems where they thrive, ensuring that these unique organisms continue to be part of the underwater landscape.
