What is the difference in vertebrate and invertebrate?

Answer 1

Invertebrates are animals that neither possess nor develop a vertebral column, derived from the notochord.

Vertebrates are animals that are any species of animals within the subphylum Vertebrata (chordates with backbones).

Answer 2

There are several notable differences between the arthropod's circulatory system and that of vertebrates. The most salient is that the arthropod's is an open system, and most vertebrates are closed; in the open system, the organs and cells are bathed in the circulatory fluid in a body cavity called a hemocoel. Also, arthropods use hemolymph, a fluid which combines the functions of blood and lymph that, by contrast, vertebrates might divert into separate systems. In addition, arthropods have a different chemistry, using the copper-based hemocyanin instead of iron-based hemoglobin to carry oxygen; this floats freely around in the circulatory fluid instead of being bound to proteins on blood cells as in most vertebrates.

In an open circulatory system, the fluid has to drain into open pores in the body cavity called ostia before being drawn into a (usually) elongated dorsal heart. This system does not effciently divert circulatory fluid to any particular region and as such, arthropods partly rely upon body movement to assist circulation.

Note that on many terrestrial/land arthropods such as insects, oxygen can be delivered directly to tissues without significant involvment in a circulatory fluid, using spiracles connected to a trachea/tracheole system.

Answer 3

The difference between a vertebrate and an invertebrate is that a vertebrate is an animal with a backbone and an invertebrates is an animal without a backbone.

Answer 4

vertebrates has backbones but invertebrates don't.
