生态学
海洋; 半咸淡水 居于水底的; 深度上下限 1 - 35 m (Ref. 9294). 熱帶; 25°N - 3°S
Eastern Pacific: Mexico to Ecuador. The Seychelles record in Smith & Smith 1963 (Ref. 1623) was based on the type specimen of Symphurus seychellensis which was previously recorded as coming from Seychelles; the correct type locality for the species is northern Peru (Ref. 26282).
東太平洋: 墨西哥到厄瓜多。 在史密斯 & 史密斯 1963 世 (參考文獻 1623) 的塞錫爾群島記錄是以先前記錄為被屬於塞錫爾群島的 Symphurus seychellensis 的模式標本為依據; 給此魚種的正確模式標本產地是祕魯北部。 (參考文獻 26282)
