Killer whales are a kind of whales, they are marine creatures, but also a class of mammals. They can also be divided into male and female. However, it is not easy to distinguish them when they are relatively young, and it is easier to distinguish them when they are adults. Usually, we can distinguish females and males by observing their appearance characteristics, and in the breeding period, we can distinguish males and females by their reproductive organs and whether they have pregnancy response.
1. Dorsal fin: Female killer whales and male killer whales have relatively large differences in dorsal fin. The first is the height of their dorsal fin. In adulthood, the dorsal fin of male orcas is very high, while the dorsal fin of female orcas is much lower. Then there is the shape of their dorsal fin, which is generally upright and basically triangular in shape in male killer whales; The dorsal fin of female orcas is generally curved and shaped like a sickle.
2. Reproductive organs: When orcas are in the breeding season, they can be judged by their reproductive organs. If they have one genital fissure and two mammary fissures, they are female orcas; If there are two genital fissures and no mammary fissures, then it is a male killer whale.
3. Size: You can also judge by their size, but if you judge from this aspect, you need the same age of the female and male. At the same age, male orcas tend to be slightly larger than females.
