Invertebrate:

Any animal lacking a vertebral column, or backbone. Invertebrates constitute the majority of the animal kingdom, including all species except those composed of vertebrate animals, which have vertebrae. The term invertebrate is also used to describe a few members of the vertebrate phylum Chordata, which lack backbones. An intermediate phylum, Hemichordata, shares some characteristics of both invertebrates and vertebrates. The invertebrates range from the simple sponges to advanced animals such as insects and cephalopod molluscs. The earliest fossil invertebrates date from Precambrian times.

Crane Fly:

Also called daddy-longlegs, common name for several families of large, slender-legged, mosquito-like flies, including the crane flies, winter crane flies, primitive crane flies, and phantom crane flies. In the larger species, the body is about 2.5 cm (1 in) long and the legs about 3.8 cm (1.5 in) long. These flies appear, often in swarms, in late summer. The family of crane flies, with nearly 15,000 species, is by far the largest family. The larvae of most species (known as leather jackets) live in the earth, but some live in water, in decomposed wood, or upon leaves of plants. The wings of the crane flies are generally clear, but are sometimes beautifully marked.
