Abstract

The Gulf of Aden (GA) experiences seasonal upwelling phenomena, fostering favorable conditions for diverse marine life. Despite this richness, the known sea urchin species in the Gulf of Aden has been limited to the common long-spined (Diadema paucispinum). Our study aimed to explore and document sea urchin diversity in this region. Through scuba diving and low tide collections from coral reefs and sandbanks, we obtained samples along the Hadhramout coast, spanning from the Qusayr area to the Aden Province coast, including Azizi Island opposite Ras Imran and the sub-district of the city of Aden. This survey revealed five sea urchin species, expanding the known taxa. For the first time in the Gulf of Aden, we qualitatively registered two regular and three irregular sea urchin species: Heterocentrotus mammillatus (Linnaeus, 1758), Stomopneustes variolaris (Lamarck, 1816), Echinodiscus bisperforatus (Leske, 1778), Clypeaster humilis (Leask, 1778), and Lovenia elongata (Gray, 1845). These findings contribute to our understanding of the Gulf biodiversity and emphasize the need for continued exploration in this region.

亚丁湾五种海胆（棘总纲，五目）的首次记录

亚丁湾（GA）经历了季节性上升流现象，为各种海洋生物提供了有利的条件。尽管如此丰富，亚丁湾已知的海胆种类仅限于常见的长刺（Diadema paucispinum）。我们的研究旨在探索和记录该地区海胆的多样性。通过水肺潜水和从珊瑚礁和沙洲采集低潮标本，我们沿哈德拉穆特海岸获得了样本，从古塞尔地区到亚丁省海岸，包括拉斯伊姆兰对面的阿齐兹岛和亚丁市的街道。这次调查发现了五种海胆，扩大了已知的分类群。我们首次在亚丁湾定性地记录了2种规则海胆和3种不规则海胆：heterocentrrotus mamillatus （Linnaeus, 1758）、Stomopneustes variolaris （Lamarck, 1816）、Echinodiscus bisperforatus （Leske, 1778）、Clypeaster humilis （Leask, 1778）和Lovenia elongata （Gray, 1845）。这些发现有助于我们对海湾生物多样性的了解，并强调了在该地区继续探索的必要性。

期刊介绍： Marine Ecology publishes original contributions on the structure and dynamics of marine benthic and pelagic ecosystems, communities and populations, and on the critical links between ecology and the evolution of marine organisms. The journal prioritizes contributions elucidating fundamental aspects of species interaction and adaptation to the environment through integration of information from various organizational levels (molecules to ecosystems) and different disciplines (molecular biology, genetics, biochemistry, physiology, marine biology, natural history, geography, oceanography, palaeontology and modelling) as viewed from an ecological perspective. The journal also focuses on population genetic processes, evolution of life histories, morphological traits and behaviour, historical ecology and biogeography, macro-ecology and seascape ecology, palaeo-ecological reconstruction, and ecological changes due to introduction of new biota, human pressure or environmental change. Most applied marine science, including fisheries biology, aquaculture, natural-products chemistry, toxicology, and local pollution studies lie outside the scope of the journal. Papers should address ecological questions that would be of interest to a worldwide readership of ecologists; papers of mostly local interest, including descriptions of flora and fauna, taxonomic descriptions, and range extensions will not be considered.
