Abstract Evidence shows that gorgonians are more resistant to ocean acidification and rising temperatures than hard corals vital reef health the reestablishment of disrupted coral communities. Gorgonian coral's resilience its diversity morphology environment make it well‐suited as a model organism for bioinspired design applied particle capture. We focus on flow near polyps, using an updated form immersed boundary method fluid–structure interaction flexible polyps surrounding water. The inlet velocity polyp elasticity simultaneously varied gain insight into (1) how these parameters affect emergent reconfiguration their tentacles (2) impacts passive Two main behaviors observed: recirculation regime, in which particles recirculate region oral disk, unidirectional move unidirectionally through without recirculation. Our results show different regimes support feeding strategies. apply filtration, discussing elastic material could benefit specific engineering applications.

Purpose The purpose of this paper is to review cases artificial reefs built through additive manufacturing (AM) technologies and analyse their ecological goals, fabrication process, materials, structural design features implementation location determine predominant parameters, environmental impacts, advantages, limitations. Design/methodology/approach analysed 16 from both temperate tropical regions. These were categorised based on the AM process used, mortar material used (crucial for biological applications), implementation. parameters are assessed how effectively designs meet stipulated demonstrate potential in comparison conventional methods preference locations these implementations. Findings overview revealed that dominant reef occurs Mediterranean Atlantic Seas, accounting 24%. remaining Australian Sea (20%), South Asia (12%), Persian Gulf Pacific Ocean, with 8%, Indian 4% all studied. It was concluded fused filament fabrication, binder jetting extrusion represent main processes build reefs. Cementitious ceramics, polymers geopolymer formulations incorporating aggregates mineral residues, wastes pozzolan reduce promote circular economy be more beneficial marine ecosystems. evaluation ranking well materials align demonstrating five ranked high effectiveness, ten projects moderate effectiveness one case low effectiveness. Originality/value represents an innovative method restoration management. offers a rapid prototyping technique validation enables creation highly complex shapes habitat diversification while diverse range benefit species’ habitats.

Concrete is the most utilized construction material worldwide. In marine environment, it subject to chemical degradation through reactions with chloride (the important ion), and sulfate magnesium ions in seawater, biodeterioration resulting from biological (initially microbiological) activities, principally acid production. These two types of corrosions are reviewed failure attempts predict degree deterioration each noted.

Coral reefs are vital ecosystems facing rapid degradation. This research explores architectural design solutions for bio-enhancing modular prototypes to support coral attachment and growth. Inspired by polyps, nine biomimetic designs were created using Maya Rhinoceros 3D optimise surfaces settlement. A total of 75 (15 × 15 cm) fabricated, incorporating four materials—PETG, concrete, oyster clay—and seven colour variations—sand, translucent green, brown, red, pink, grey, reddish. The findings indicate that printing with PETG was the most efficient fabrication method but required structural long-term underwater testing, while concrete demonstrated potential self-sustaining structures. study highlights role in marine restoration, promoting biodiversity resource-efficient solutions. By integrating corals into design, these structures can self-grow adapt, reducing material consumption maintenance.
