Cytocompatibility of 5 coral aquaculture skeleton species derived from two families (Acroporidae and Pocilloporidae) was studied over the course of in vitro culturing in continuous human fibroblast culture by the MMT test. Biocompatibility and capacity of scaffold to "transfer" cell cultures (specifically, multipotent mesenchymal stromal cells) to sites of implantation were studied in vivo by subcutaneous implantation of skeletal fragments to rats. All coral skeleton aquaculture specimens were cytocompatible (nontoxic and with surface matrix characteristics satisfactory for cells), biocompatible, and could be tried as 3D matrices for bone tissue engineering.

Stirring up the muck: the systematics of soft-sediment Fionidae (Nudibranchia: Aeolidina) from the tropical Indo-Pacific.
PeerJ

The tropical Indo-Pacific aeolid nudibranchs of the Fionidae are poorly known and have not been studied in a concerted manner. Many undescribed species are found throughout the Indian and Pacific Oceans and are concentrated in the Coral Triangle. With the recent publication of a revised systematic arrangement of the Fionidae, documentation and description of new taxa of Fionidae is especially warranted.

Article Synopsis
- Assessing ocean biodiversity is challenging, with limited global indicators highlighting overfishing as a major threat, impacting shark and ray populations.
- Analysis of 1199 species shows their populations have declined by 50% since 1970, with a 19% increase in extinction risk, particularly in regions with high coastal human populations.
- Sustainable fishing practices and restrictions on threatened species can help prevent further biodiversity loss and maintain ecological balance in marine environments.
Parasitism in coral reefs: Trophic ecology of crustacean ascothoracidan parasites and their coral hosts from Malaysia.

Coral reefs house a great variety of symbiotic associations, including parasitism. One of the crucial issues in the host-symbiont interactions is the parasites' feeding mode. Does the parasite/symbiont use the host's tissues for nutrition, steal food from the host's digestive system, or take food directly from the environment? However, most of the parasitism in corals is endosymbiotic (endoparasitic).

Cultivating microalgae for the remediation of aquaculture wastewater provides a promising solution for pollution control. However, the economic viability of this approach faces challenges due to the high costs associated with microalgal biomass harvesting. This study aims to address this issue by immobilizing microalgae onto coral velvet carriers, enhancing the efficiency of biomass recovery.

Article Synopsis
- Atlantic reef-building corals are declining due to climate change, disease, pollution, and human activities, prompting a reassessment of their extinction risk under the IUCN Red List.
- The latest evaluation shows an increase in the percentage of species at high extinction risk, with nearly 46% to 54% of shallow water corals now classified as threatened, compared to 15% to 40% in 2008.
- Although there's been a slight improvement in coral coverage over historical data, projections indicate that severe bleaching events could significantly threaten the future survival of 26 species, which are now labeled as Critically Endangered.
