博物馆和私人机构的自然历史收藏品可以发挥重要作用，支持生物多样性保护方面的决策。海马的数量在全球范围内下降，而许多地区仍然缺乏数据，包括西非海岸等商业贸易繁忙的地区。在这项工作中，最初审查了Macaronesia（亚速尔群岛，马德拉群岛和加那利群岛）博物馆和公共机构的海马收藏品（1）以确定以前没有确定的标本，（2）纠正Macaronesia和邻近西非海岸的物种确定。对形态学数据（3）进行了测试，以了解Macaronesia和邻近西非海岸之间以及Macaronesia和邻近西非海岸之间海马的表型变异。已确认该地区存在海马（短吻海马）和海马（西非海马），包括在沿着以前的地理分布范围内发现新的情况。形态分析分区海马物种和几个形态型内和Macaronesia和邻近的西非海岸之间。这种表型可塑性与颅骨形态学有关。这种差异是追踪不同物种和起源的海马种群的有用工具。这里提出的新信息，是有价值的，以改善海马的管理和保护，特别是在非法贸易或其他人为活动的威胁地区。
Natural history collections from museums and private institutions can play an important role supporting decisions in biodiversity conservation. Seahorse populations have suffered a worldwide decline, while many areas remain data deficient including areas subjected to heavy commercial trading, such as the coasts of West Africa. In this work, seahorse collections from museums and public institutions in Macaronesia (Azores, Madeira and the Canary Islands) were initially reviewed (1) to identify specimens not previously determined, and (2) to correct species determinations from Macaronesia and adjacent West African coasts. The morphological data (3) were tested for phenotypic variation of seahorses within and between Macaronesia and adjacent West African coasts. The presence of Hippocampus hippocampus (short-snouted seahorse) and Hippocampus algiricus (West African seahorse) was confirmed for the area, including new sightings along previous geographical distribution ranges. Morphological analyses partitioned seahorse species and several morphotypes within and between Macaronesia and adjacent West African coasts. This phenotypic plasticity was associated with cranial morphology. Such differences are a useful tool for tracking seahorse populations of varying species and origins. New information presented here, is valuable for improving the management and conservation of seahorses, particularly in areas threatened by illegal trading or other anthropogenic activities.
