Detailed Description

Non-native or introduced populations of Asian Swamp Eels (family: Synbranchidae) exist in the wild in parts of Florida, Georgia, and Hawaii. This video shows predatory behavior of captive individuals. Swamp eels shown feeding in this video include two different species, the first (tentatively identified as Monopterus albus) is a wild-caught specimen taken from Florida waters and the second is Monopterus cuchia obtained from a commercial source. The small prey fish are juvenile Largemouth Bass (Micropterus salmoides). Swamp eels generally take prey that are smaller than their mouth gape size, but -- as shown in the video -- they will attack and consume larger prey
