Overview

The greater flowerbud coral (Anthothela grandiflora) is a soft coral species characterized by its distinctive flower-like polyps that can expand to impressive sizes when feeding. This colonial cnidarian displays vibrant coloration ranging from deep purples to bright oranges, with its branching structure creating important three-dimensional habitat complexity on reef systems. As a filter feeder, it plays a crucial role in nutrient cycling and provides shelter for numerous small reef fish and invertebrates.

The greater flowerbud coral (Anthothela grandiflora) faces severe threats from ocean warming and acidification, which disrupt its calcium carbonate skeleton formation and cause bleaching events. Coastal development, pollution, and destructive fishing practices further degrade its deep-sea habitat, while its extremely limited distribution makes it particularly vulnerable to localized disturbances.

Threat summary

Habitat

Greater flowerbud coral inhabits deeper reef slopes and walls at depths of 15-40 meters, typically in areas with moderate to strong currents that facilitate feeding. It shows preference for rocky substrates and reef drop-offs where it can attach securely while accessing nutrient-rich waters flowing along the continental shelf.
