Summary: In vitro culture method for coral ovaries was developed, optimized with specific culture medium and antibiotics, demonstrating the importance of these factors in maintaining structural integrity of ovaries. Cultured ovaries for 6 days showed presence of oogonia and expression of vitellogenin, indicating the potential for studying coral oogenesis effects.

Summary: In the 20-year history of Zootaxa, 32 papers focused on Scleractinia have been published, accounting for around 0.10% of all papers. The papers are divided into those related to living species and fossil species, with 2013 being the peak year for publication.

Summary: Knowledge of early life histories of scleractinian corals is important for ecological studies and aquaculture techniques. This study focused on Fimbriaphyllia ancora and found that it releases buoyant eggs and develops into swimming planula larvae within 48 hours after fertilization. The eggs are rich in wax esters and glycogen, and the concentrations change during development. Furthermore, settlement assays showed the preference of F. ancora planulae for dead coral debris.

Summary: Recent studies have shown that Coelastrea aspera in Japan can be genetically and morphologically separated into two main groups based on their distribution and reproductive behavior. One group is found only in reef regions and releases egg-sperm bundles, while the other group is widely distributed in both reef and non-reef regions and releases eggs and sperm separately.

Summary: For the first time, the complete mitogenome sequence of the soft coral Eleutherobia rubra was sequenced and analyzed. The study revealed the length, gene composition, and base composition of the mitogenome.

Summary: A new genus and three new species in the family Schizopathidae were described based on morphological data. The new genus resembles Telopathes in appearance but differs in certain features. Molecular analysis supported the significance of these anatomical differences. Interestingly, the three new species did not form a monophyletic clade based on mitochondrial DNA, suggesting the possibility of morphological convergence.

Summary: In this study, we conducted karyotype analysis and molecular cytogenetic studies on Favites pentagona, a coral species predominantly found in the western coast of Japan. G banding analysis revealed the presence of a homogenously staining region (HSR) on chromosome 10 in over 50% of examined metaphase spreads. Further investigation through fluorescence in situ hybridization (FISH) and DNA sequencing confirmed that this HSR consisted of sequences derived from 18S ribosomal RNA (rRNA) genes. Additionally, we developed four chromosomal FISH markers from repetitive genes, which will contribute to improved karyotyping and understanding of genetic structure and chromosome organization in F. pentagona. Furthermore, these improvements in karyotyping will serve as a foundation for constructing a chromosome-level genome assembly for this coral species.

Summary: Sarcophyton subviride Tixier-Durivault, 1958, a soft coral, is reported for the first time in Indian waters. This species has previously been documented in other regions, but this is the first occurrence in Great Nicobar Island in the Andaman Sea. Variations in the structural features of the colony were observed and discussed in comparison with other type specimens.

Summary: This study investigated the ecological features and environmental factors of the Xuwen coral reef in 2020. The results showed a significant decrease in coral coverage compared to 2004, with dominant genera still being Goniopora and Porites. The coral community was characterized by low diversity. The mass coral bleaching event in the NSCS in 2020 did not cause severe coral death in the short term on the Xuwen coral reef. The growth of the coral community was greatly affected by high suspended solids and nutrient levels, related to current, mariculture, and coastal erosion. Anthropogenic activities such as coastal aquaculture and fishing were identified as the major factors leading to the reduction in coral coverage on the Xuwen coral reef in the past 10 years.

Summary: In August to September 2020, a severe anomaly in sea surface temperature in the South China Sea led to a mass coral bleaching event in Hainan Island and the Beibu Gulf. Field surveys found that a majority of surveyed sites experienced bleaching, with western Hainan Island and Weizhou Island being the most affected. The results also showed a strong correlation between sea surface temperature anomalies and bleaching percentage, with lower diversity and coral cover associated with higher anomalies. Different coral taxa exhibited varying levels of resistance to heat stress.

Summary: This study provides the first description of the reproductive cycle of the main builders of the Mediterranean coral reef, Phyllangia americana mouchezii and Polycyathus muellerae. It focuses on both sexual and asexual reproductive activity and investigates the relationship between gametogenesis and seawater temperature.
