A field trip carried out in July 2023 reveales some aspects of natural biodiversity in Sfântu Gheorghe, a locality from Tulcea County placed in the Danube Delta Biosphere Reserve. During the observation period, the following fish species were noticed at the shore of the Black Sea: Abramis brama, Callionymus risso, Cyprinus carpio, Esox lucius, Engraulis encrasicolus, Gymnammodytes cicerelus, Ophidion rochei, Pomatoschistus minutus and Trachurus mediterraneus. Of them, only for four species were given data upon the total length (cm) and total weight (grams), taking into account the number of specimens and the quality of preservation. Among the invertebrates gathered from the vegetation, were registered: gastropods (Cepaea hortensis, Helicella sp., Planorbarius corneus), spiders (Agelena sp., Araneus diadematus, Argiope bruennichi, Cheiracanthium sp., Tetragnatha sp.) and insects, mainly from Orthoptera order. In addition, the preliminary study of the coastal flora of the Sfântu Gheorghe indicated a total of 74 plant species, belonging to a number of 37 families. Some of the species are included in the categories of rare species.
