" When pigs live in the wild-or even wild boars-these animals live in groups. They need to communicate with their conspecifics to be able to live."

“当猪生活在野外，甚至还是野猪时，这些动居。它需要交流才能生存下去。”

Like in almost every other species,   those individuals living in colder climates tend to be larger than  their warmer weather conspecifics.

几乎所有其他种一样，那些生活在寒冷气候中的个体往往比气候温暖的种个体更大。
