An invertebrate is any animal that does not have a vertebral column ( in humans this is the backbone or spine ), this actually constitutes 98% of all animal species ( basically all animals except for fish, reptiles, amphibians, birds and mammals).

The term invertebrate is used usually for the kind of animal who has no backbone. There are numerous examples of this kind of animals in this world and the prime among them are worms. You can see how flexibly they move and an animal with backbone can seldom move like them.

Though the word is a technical one, it is so often used in day-to-day conversation that it is no more remain technical. But sometimes there arise a confusion of this word with that of its antonymous term vertebrate. People know that one is with bone and another one is without but still the confusion prevail that which one is what.

To make the meaning clear you just have to keep this in mind: 'in' conveys the idea of no. If you remember this, the other meaning will be obvious to you.

An invertebrate is an animal without a vertebral column(spine or backbone). The group includes 95% of all animal species — all animals except those in the Chordate subphylum Vertebrata (fish, reptiles, amphibians, birds, and mammals).
