Fifteen species of sea anemones (Cnidaria, Actiniaria) have been recorded so far in the Colombian Caribbean, comprising approximately 28% of the total number of known species in the Caribbean Sea. Most species recorded are associated with coral reef communities. However, in the region, no records of sea anemones are known from areas with high sedimentation conditions as is characteristic along the coastline of the Atlántico Department, in Colombia. In this area, organisms are exposed to a high degree of turbidity and sedimentation (~143.9x106 t year-1) as a result of their proximity to the Magdalena River mouth and the 26 micro-basins that flow along its coastline. Several observations and collections were made on soft bottoms, rocky, and artificial substrates in the sectors of Puerto Velero and Caño Dulce to determine the fauna that exist under these conditions. Four species of sea anemones were found belonging to the families Actiniidae and Aiptasiidae, and images from living specimens and cnidae are provided. Bunodosoma cavernatum and Exaiptasia diaphana are here recorded for the first time from the Colombian Caribbean. An updated list of sea anemones in the Colombian Caribbean, now comprising 34 taxa (i.e., 21 species and 13 identified at supra-specific levels), is provided.
到目前为止,在哥伦比亚加勒比地区已经记录了 15 种海葵(刺胞动物门,海葵目),约占加勒比海已知物种总数的 28%。记录的大多数物种都与珊瑚礁群落有关。然而,在该地区,没有记录到在高泥沙条件下的海葵,而这种情况在哥伦比亚大西洋省的海岸线很常见。在这个地区,由于靠近马格达莱纳河口和沿着其海岸线流动的 26 个小流域,生物体会暴露在高度浑浊和泥沙沉积的环境中(每年约 143.9x106 吨)。在 Puerto Velero 和 Caño Dulce 等地区的软底、岩石和人工基质上进行了几次观察和采集,以确定在这些条件下存在的动物群。发现了 4 种海葵,分别属于海葵科和 Aiptasiidae 科,并提供了活体标本和刺细胞的图像。Bunodosoma cavernatum 和 Exaiptasia diaphana 是首次从哥伦比亚加勒比地区记录到的。提供了一份更新的哥伦比亚加勒比海海葵清单,现在包括 34 个分类群(即 21 个物种和 13 个在超种水平上确定的分类群)。
