Common Genet vs Otter: Who Actually Wins?

The otter wins, and the main reason is size. A typical Eurasian otter, the species whose range overlaps the common genet's in Iberia and North Africa, weighs roughly 7 to 12 kg. A common genet is a slender 1.3 to 2.3 kg climber, so the otter carries about four to six times its mass. That weight supports a thick neck, a broad skull and a crushing bite built for crayfish shells and slippery fish. Dense, oily fur and a muscular, tubular body also absorb the kind of slashing bites a genet relies on. The genet is the better athlete in three dimensions. It has retractable claws, an excellent sense of balance and a long counterweight tail, so in trees or rock clefts it can simply leave. But if the two are forced into contact on the ground or near water, the otter's mass, grip and tenacity decide it quickly. The genet's best result is escaping, not beating the otter.
