Monatsbericht der Akademie Wissenschaften zu Berlin, 1868. Channa striata, the striped snakehead, is a species of snakehead fish. The fishes form a spawning embrace in which the male wraps around the female, fertilising the eggs as they are released, The common snakehead (along with other large snakehead species) is a favoured food fish in much of Southeast Asia, including Singapore, ]. They exhibit this activity by hitting the snout and the vent of the female frequently, while gametes are being released. 2011.
