The common Caribbean starfish Oreaster reticulatus (Linnaeus) feeds on sponges by everting its stomach onto a sponge and digesting the tissue, leaving behind the sponge skeleton. In the San Blas Islands, Republic of Panama, 54.2% of the 1549 starfish examined from February 1987 to June 1990 at eight sites were feeding, and 61.4% of these were feeding on sponges, representing 51 species. Sponges were fed on disproportionately heavily in comparison to their abundance, which was only 9.7% of… 
Anti-predatory effects of organic extracts of 10 common reef sponges from Zanzibar
TLDR
Low predatory fish abundances likely resulted in a high prevalence of chemically undefended sponges dominate the reef at Bawe Island, Zanzibar, subjecting reef-building corals to a higher competitive pressure.
Collaboration among sponge species increases sponge diversity and abundance in a seagrass meadow
TLDR
Community ecology theory relating to diversity patterns in sessile organisms has focused on competition between space-requiring neighbors as the underlying process that inevita- bly decreases diversity unless curtailed, but sponge species, with their propensity for engaging in beneficial interactions with neighbors, demand expansion of the theory to acknowledge how collaboration can increase abundance and species diversity within a community.
A Qualitative Assessment of Sponge-Feeding Organisms from the Mexican
TLDR
To identify the main predators of sponges, and their principal prey, in two localities from the Sea of Cortez, stomach contents from 13 species of fishes, 23 species of opisthobranchs, and 4 species of echinoderms were analyzed.
Variable effects of symbiotic snapping shrimps on their sponge hosts
TLDR
The costs and benefits suggest that Synalpheus has variable effects on sponges: positive effects onsponges in the presence of predators, and/or when spongees are decreasing in mass, but a negative effect on sp sponge growth during periods of active sponge growth.
A Qualitative Assessment of Sponge-Feeding Organisms from the Mexican Pacific Coast
TLDR
To identify the main predators of sponges, and their principal prey, in two localities from the Sea of Cortez, stomach contents from 13 species of fishes, 23 species of opisthobranchs, and 4 species of echinoderms were analyzed.
Stargrazing: Trophic ecology of sea stars in the Galápagos rocky subtidal zone
Sea stars (class Asteroidea) can play powerful and wide-ranging roles as consumers of algae and prey items in benthic ecosystems worldwide. In the Galápagos rocky subtidal zone, sea stars are
Spongivory by juvenile angelfish (Pomacanthidae) in Salvador, Bahia State, Brazil
TLDR
Findings indicate that juveniles of all three species of angelfish are generalists in the consumption of sponges in Brazil, a diet similar to that of the adults.
Ecological interactions of marine sponges 1
Sponges interact with most other organisms in marine systems as competitors, symbionts, hosts of symbionts, consumers, and prey. Considerable creative energy has been required to study and describe
Larval Behaviours and Their Contribution to the Distribution of the Intertidal Coral Reef Sponge Carteriospongia foliascens
TLDR
The abundance of C. foliascens and substrate availability was first quantified to investigate the influence of substrate limitation on adult distribution, and it was found that suitable settlement substrate (coral rubble) was not limiting in subtidal habitats.

TLDR
No strong evidence is provided by data that fish predation is a significant factor in limiting sponge distribution in the West Indian region.

TLDR
Data from the field surveys and the energetics studies suggest that Mycale is prevented from dominating the space resource by the predation of two asteroids.

TLDR
By their remarkable regeneration capacity and effective anti-predatory mechanisms these sponges appear to be well adapted to the dynamic reef environment.

TLDR
Although numerous seaweed characteristics can deter some herbivores, the effects of morphology and chemistry have been studied most thoroughly and these types of seaweeds may be considered herbivore tolerant.

Investigation of the relationship between invertebrate predation and biochemical composition, energy content, spicule armament and toxicity of benthic sponges at McMurdo Sound, Antarctica
TLDR
The high incidence of toxicity in antarctic sponge indicates that the current hypothesis suggesting a simple inverse relationship between toxicity and latitude in marine sponges is invalid, and there was little correspondence between the energetic composition or spicule contents of the spongees and feeding patterns (electivity indices) of sponge-eating predators.
