Long-Branch Sea Pen [Xenogorgia]

Description

Xenogorgia is a genus within the family Umbellulidae, distinguished by its unique morphology and habitat preferences. These sea pens possess a central stalk from which long, slender branches extend, creating a complex structure that supports numerous polyps. Xenogorgia species are primarily found in deep-sea environments, often on sloping sea floors or near underwater features that provide a suitable substrate for anchorage. The intricate branching pattern of these organisms allows for an efficient capture of suspended particles and plankton, facilitating their survival in nutrient-poor deep-sea conditions. Their presence contributes to the structural complexity and biodiversity of deep-sea ecosystems.
