1. During the last decade, the common dolphin (Delphinus delphis) has become the second most sighted species in Israeli coastal waters, after the common bottlenose dolphin. Documentation mostly relies on opportunistic, photo and/or video‐backed second‐party reports, delimited within a 10 km near‐shore strip.
2. Sightings occur year round, are confined to the southern part of the Israeli coast and typically comprise relatively large groups (mean ± SD: 21.5 ± 13.3), often with young calves.
3. Strandings are relatively scarce, typically one per year, and have so far yielded five upper digestive tract contents for diet analysis.
4. Cephalopods comprised 1.2% of the estimated number of prey items in the combined content. Surprisingly, by far the most abundant and prevalent prey item found (57% of pooled prey items; present and dominant in four out of five tracts) was the Balearic eel (Ariosoma balearicum), a sand burrower which is also a major dietary component of the common bottlenose dolphins.
5. Bottlenose dolphins in Israel are known to forage in association with bottom trawlers, leading to the notion that common dolphins also make use of this foraging mode. Indeed, in addition to their association with purse seiners, they have been documented accompanying bottom trawlers, by both day and night. The slender Balearic eels are frequently found protruding from the net's eyes, presumably making easy prey for both dolphin species.
6. Information gaps on common dolphins include range extension to the south/south-west, abundance estimation and genetic flow/isolation. Even so, its unusual diet and the fact that the closest known populations to the north/north-west are from the Aegean Sea, were major considerations in the recent designation of the ‘Coastal Shelf Waters of the South-east Levantine Sea’ as a Mediterranean Important Marine Mammal Area.

常见于以色列南部沿海地区的普通海豚表现出不常见的饮食习惯

1. 在过去的十年中，普通海豚（Delphinus delphis）已成为仅次于宽吻海豚的第二大以色列海域物种。文档主要依靠机会主义，照片和/或视频支持的第二方报告，范围在10公里的近岸带内。
2. 目击全年发生，被限制在以色列海岸的南部，通常包括相对较大的群（平均±标准差：21.5±13.3），通常有幼小犊牛。
3. 绞股相对稀少，通常每年一次，到目前为止，已经为饮食分析产生了五种上消化道内容物。
4. 头足类动物占猎物估计数量的1.2％。令人惊讶的是，迄今为止发现的最丰富和普遍的猎物（占混合猎物的57％；在五分之四的区域中占主导地位）是巴利阿里鳗鱼（Ariosoma balearicum），它是沙地穴鼠，也是沙棘的主要饮食成分。普通的宽吻海豚。
5. 众所周知，以色列的宽吻海豚会与底拖网渔船一起觅食，这导致了一种观念，即普通海豚也利用这种觅食模式。的确，除了它们与围网渔船的联系外，白天和黑夜它们都被记录在海底拖网渔船的陪伴下。人们经常发现细长的巴利阿里鳗鱼从网眼突出，大概是这两种海豚物种的容易捕食对象。
6. 常见海豚的信息缺口包括向南/西南延伸的范围，丰度估计和遗传流/隔离。即便如此，它的不寻常饮食以及与北/西北最接近的已知种群都来自爱琴海这一事实，是最近将“东南黎凡特海沿海陆架水域”指定为“爱琴海”的主要考虑因素。地中海重要海洋哺乳动物区。
