A specimen is a sample of something, like a specimen of blood or body tissue that is taken for medical testing. The noun specimen comes from the Latin word specere, meaning âto look.â Biologists collect specimens so they can get a better look at something to study it. The idea is that, with a good specimen, you can learn about an entire group: it's a good representation. That meaning is echoed in the slang use of specimen, a strong, healthy and attractive person.
A species is a category within the classification system. Living things of the same type belong to the same species. For example, humans are one species and dogs are another species. Individuals of the same species can reproduce to make more individuals of the same species. Two individuals belonging to different species cannot normally reproduce together. If they do, their offspring is usually infertile and unable to reproduce.
