“及其同类”可以翻译为 "and its kind" 或 "and its like"。
"and its kind" 更侧重于指同一类别或类型的事物，强调共同特征或属性。
"and its like" 则更广泛，可包含相似或相关的事物，不局限于严格分类。
具体使用哪个短语取决于语境和想要表达的含义。例如：
“禁止携带易燃易爆物品及其同类（物品）。” 可译为 "Flammable and explosive materials, and their kind, are prohibited."
“这种行为在动物界中并不罕见，及其类似行为在其他物种中也有发现。” 可译为 "This behavior is not uncommon in the animal kingdom, and its like has been observed in other species."
