All species have a life cycle that is divided into stages- these selections cover most of the general life stages of plants, chordates, marine invertebrates and insects. DO NOT ASSUME the specimen you are working with is a fully developed adult. Unless you know for sure, or the label states the biological stage, leave this blank.
Adult: fully developed animal.
egg: oval or round object, usually containing a developing embryo.
embryo: unborn/unhatched animal. For our uses, this applies to animals only.
hatchling: recently emerged from an egg
immature: as a biological stage, not a determination of a mental state. A general term grouping together hatchling, juvenile, sub-adult and so on.
juvenile: of or relating to young birds or other animals. Again, not a determination of mental state.
