a crocodile is a reptile that is very fierce and can hunt both in the water and on land. Otters are mammals that also move and hunt in the water. Crocodiles and otters sometimes use fish in the water as their food, so they may have conflicts when hunting. At this point, crocodiles and otters may fight, but a strange phenomenon is that very fierce crocodiles are no match for otters. Although crocodiles may be larger than otters in terms of size, sometimes crocodiles can't beat otters.
It has been introduced above that when the crocodile fights with the otter, it may not be able to beat them, which in many people's eyes is not dead, because the crocodile is, after all, a recognized very fierce reptile, and they will even take the initiative to attack humans. The most important reason why they can't beat otters is that crocodiles are cold-blooded animals, and otters are warm-blooded animals, in terms of blood circulation, crocodiles are not as good as otters, so otters will be slightly better in fighting, can persist for a longer time, and have a higher degree of flexibility.
In addition, from the point of view of body structure, otters have very thick fur, which can play a very effective role in protecting themselves, and is a very effective means of defense. Moreover, from the comparison of vision, otter's vision is also relatively strong, whether in fighting, or in predation, can play an important role.
