“…Similarly, in the Marsouins River, the decline in GSI values occurred in July and September [3]. An increase in GSI value is an indicator of the spawning season [22]. It can be understood that May is thought to be the spawning season for S. lagocephalus and the downstream part of the river as a spawning area for S. lagocephalus in the Cibareno River.…”

The red-tailed goby (Sicyopterus lagocephalus) is an Indonesian endemic fish that can be found in the Cibareno River. The red-tailed goby is an amphibious fish. The dam construction plan in Cibareno River is expected to affect the reproduction pattern and survival of red-tailed goby. This study aims to analyse the reproductive biology of long-tailed gobies (Sicyopterus lagocephalus, Pallas 1770). The study was conducted over four months (May, June, July and September 2022) in Cibareno River, Sukabumi, West Java using purposive sampling method. A total of 163 fish samples were caught during the study, consisting of 106 males and 57 females. The total length range of fish caught was 32 mm to 150 mm. The sex ratio of male and female fish was 1:0.54 (unbalanced). Fish condition factor ranged from 1–1.6. The month of May and the downstream part of the river are thought to be the peak of S. lagocephalus spawning characterized by the highest gonadsomatix index in that month and location. The spawning pattern of S. lagocephalus is total spawner. The construction of the dam had an impact on the spawning migration of S. lagocephalus to the downstream of the river being blocked. In addition, S. lagocephalus in the downstream of the river are also prevented from migrating upstream to forage.

Chiton articulatus is a species of mollusk living in the tropical Pacific intertidal rocky shores of Mexico. This species feeds on solid waste organic sources, including hard crustose algae that grow on rocky substrates, by grazing on them with its radula, a flexible chitinous membrane lined with mineralized major lateral teeth. In this study, the composition, morphology, and resulting mechanics of the mature teeth of this species, which have yet to be examined, are revealed. The results show the presence of multiphasic mature teeth, each consisting of aligned hard magnetite nanoparticles on the leading edge of the tooth underneath which are magnetite lamellae, followed by goethite, lepidocrocite, and eventually hydroxyapatite near the trailing edge. This multiregional structure demonstrates a gradation in hardness as well as different microstructural features integrated with tough interfaces. The combination of these microstructural and phase arrangements results in an abrasion‐resistant tough structure with a self‐sharpening ability. The results of this work will help contribute to developing new bioinspired designs while also helping to understand the evolution and feeding habits of these intriguing invertebrates.
