“…It may have been translocated or migrated naturally. A report from Taiwan found T. hoshinota released brooded larvae monthly over five months (April-August), potentially releasing numerous recruits to an area, but the dispersal of larvae was localised (metres) unless they are swept away by strong waves [41]. Juvenile T. hoshinota had spicules at five days and oscula at seven days after settlement, at which time they began overgrowing live coral [42].…”

The cyanobacteriosponge Terpios hoshinota has been reported throughout the Indo-Pacific including the Great Barrier Reef, Australia. The species encrusts live coral, giant clams, and other benthos and can be a threat to benthic communities on coral reefs. The Kimberley region of Western Australia has some of the least impacted reefs globally. We report for the first time the presence of T. hoshinota in the eastern Indian Ocean on Kimberley inshore coral reefs. Given its invasive potential, reef health surveys should include this species, and monitoring approaches developed to audit the remote Kimberley for this and other invasive species.

“…Hermaphroditism was the prominent mode of gamete development in this bioregion, found for three of these four species. Furthermore, only one instance of asexual reproduction has been recorded in this bioregion: fragmentation in Terpios hoshinota (Nozawa, Huang, & Hirose, 2016). Reproduction for sponges in Tropical Australia has been characterised solely on the GBR, with reproductive information reported for 11 different species (e.g.…”

“…Asexual reproduction has only been recorded for one species to date in this bioregion, where Amphimedon chloros was found to undergo fragmentation (Ilan, Gugel, & Van Soest, 2004). Reproduction in South East Asia has been characterised for four species, with all exhibiting viviparity and seasonal reproduction (Asa et al ., 2000; Chung et al ., 2010; Huang et al ., 2016; Nozawa, Huang, & Hirose, 2016). Hermaphroditism was the prominent mode of gamete development in this bioregion, found for three of these four species.…”

Interocean patterns in shallow water sponge assemblage structure and function

Sponges are a major component of benthic ecosystems across the world and fulfil a number of important functional roles. However, despite their importance, there have been few attempts to compare sponge assemblage structure and ecological functions across large spatial scales. In this review, we examine commonalities and differences between shallow water (<100 m) sponges at bioregional (15 bioregions) and macroregional (tropical, Mediterranean, temperate, and polar) scales, to provide a more comprehensive understanding of sponge ecology. Patterns of sponge abundance (based on density and area occupied) were highly variable, with an average benthic cover between ~1 and 30%. Sponges were generally found to occupy more space (percentage cover) in the Mediterranean and polar macroregions, compared to temperate and tropical macroregions, although sponge densities (sponges m–2) were highest in temperate bioregions. Mean species richness standardised by sampling area was similar across all bioregions, except for a few locations that supported very high small‐scale biodiversity concentrations. Encrusting growth forms were generally the dominant sponge morphology, with the exception of the Tropical West Atlantic, where upright forms dominated. Annelids and Arthropods were the most commonly reported macrofauna associated with sponges across bioregions. With respect to reproduction, there were no patterns in gametic development (hermaphroditism versus gonochorism), although temperate, tropical, and polar macroregions had an increasingly higher percentage of viviparous species, respectively, with viviparity being the sole gamete development mechanism reported for polar sponges to date. Seasonal reproductive timing was the most common in all bioregions, but continuous timing was more common in the Mediterranean and tropical bioregions compared to polar and temperate bioregions. We found little variation across bioregions in larval size, and the dominant larval type across the globe was parenchymella. No pattens among bioregions were found in the limited information available for standardised respiration and pumping rates. Many organisms were found to predate sponges, with the abundance of sponge predators being higher in tropical systems. While there is some evidence to support a higher overall proportion of phototrophic species in the Tropical Austalian bioregion compared to the Western Atlantic, both also have large numbers of heterotrophic species. Sponges are important spatial competitors across all bioregions, most commonly being reported to interact with anthozoans and algae. Even though the available information was limited for many bioregions, our analyses demonstrate some differences in sponge traits and functions among bioregions, and among macroregions. However, we also identified similarities in sponge assemblage structure and function at global scales, likely reflecting a combination of regional‐ and local‐scale biological and physical processes affecting sponge assemblages, along with common ancestry.

“…Several studies have shown that cyanobacteria play important roles in the sponge’s growth and competition with corals. For instance, high numbers of cyanobacteria can be observed in the sponge’s larvae (16, 17), suggesting that they are transmitted vertically during embryogenesis in this particular sponge (18). Second, in situ light shading was shown to discontinue T. hoshinota expansion (19).…”

Terpios hoshinota is a ferocious, space-competing sponge that kills a variety of stony corals by overgrowth. Outbreaks of this species have led to intense coral reef damage and declines in living corals on the square kilometer scale in many geographical locations. Our large-scale 16S rRNA metagenome study across three oceans revealed that the core microbiome of T. hoshinota included OTUs related to Prochloron, Endozoicomonas, Pseudospirillum, SAR116, Magnetospira, and Ruegeria. A Prochloron-like OTU was the most dominant cyanobacterium in T. hoshinota in the western Pacific Ocean, South China Sea, and Indian Ocean. The high-quality draft genome of the Prochloron-like cyanobacterium and our pigment analysis revealed that, unlike the previously described Prochloron species and their genomes, this bacterium had phycobiliproteins and phycobilins and lacked chlorophyll b. Furthermore, the phylogenetic analyses demonstrated that the bacterium was phylogenetically distinct to Prochloron, strongly suggesting that it should be a sister taxon to Prochloron; we therefore proposed this symbiotic cyanobacterium as a novel species under a new genus: Candidatus Prochlorobium terpiosii. In addition, we also characterize the metabolic potentials of the cyanobacterium in carbon and nitrogen cycling and propose a model for the interaction between Ca. Pb. terpiosii LD05 and T. hoshinota. This study builds the foundation for T. hoshinota's microbiome and paves a way for understanding the ecosystem, invasion mechanism, and causes of outbreak of this coral-killing sponge.
