oops hope i'm invited, but i agree with sicklid-holic, the dovi, like the white shark, is a point blank predator, it strikes, and kills in a burst of speed, with it's aerodynamic shape, menacing look, and an arsonal of large pointy teeth, and a nasty bite, it truly is the supreem predator. the umbee on the other hand is like a a killer whale, large, and intimidating, but not exactly capable of leaving one in a state of fearful awe, i've owned both my dovi was 18 inches when i was forced to part with him, and my umbee was about the same, both were devils, but the dovi, struck most fear in the people, who saw him, and the large food items he bit to pieces...the umbee just killed things for killing things, the dovi ate things outright, BIG things... he was and still is a large mouth bass from HELL...
