Abstract

This research examines the taxonomic classification and environmental implications of recent benthic foraminifera found along the coast of Anthony's Bay, Roatan, Northeast Honduras. Five sediment samples weighing 300 grams were collected from the beach at depths of less than one meter. Standard processing methods were used to isolate foraminifera from these samples. Eleven benthic foraminifera species were identified, including Archaias angulatus, Cibicidoides crebbsi, Lenticulina formosa, Peneroplis pertusus, Peneroplis planatus, Procerolagena gracilis, Pyrgo lucernula, Siphonaperta irregularis, Spiroloculina tenuiseptata, Technitella legumen, and Textularia agglutinans. Additionally, one planktonic foraminifera species, Orbulina universa, was recorded. The most abundant species observed were Peneroplis pertusus and Peneroplis planatus. Across all five samples, a significant presence of coral fragments was noted alongside the benthic foraminifera community. The molluscan composition was primarily gastropods, with notable occurrences of bryozoans and echinoderms. The elevated abundance of coral fragments in these samples highlights a substantial ecological concern, indicating potential adverse impacts from human activities and climate change.
