Vertebrates belong to the subphylum Vertebrata – the largest subphylum of chordates containing several groups of large land animals including mammals, birds, reptiles, amphibians and fishes. Vertebrates have spinal columns and backbones. There are now around 58,000 species of vertebrates.

cleavage stage
Can trauma cause vertebral hemangioma?
Vertebral hemangiomas are really verterbral vascular malformations, either venous, lymphatic or arterio-venous. Hemangiomas only occur in infants but are often confused with their cousin - the vascular malformation. And, yes, it is typical for a venous malformation to arise from direct trauma. Since it is in the spinal area the person with this condition should contact one of our medical experts or someone who really knows how to treat these lesions. Boston Children's Hospital has a huge team and they treat adults and children and will review imaging studies for free. They also accept most insurances. You can call and ask for the Vascular Anomalies Program at Boston Children's.

Are all animals with exoskeletons vertebrates or invertebrates?
An exoskeleton is not an animal, but a part of an animal. A skeleton is simply something in an animal that provides as a structural support and (except for sponges) something to anchor the muscles to. There are two sorts of skeleton:
- Endoskeletons, as the name indicate, are part of the animal's interior. This includes a human's bones, which are inside the body. They allow for much more flexibility and do not need to moult their entire skeleton at once.
- Exoskeletons, on the other hand, are on the animal's exterior, and serve as a sort of armour. The arthropods, which include the insects, crustaceans, millipedes and centipedes, arachnids, trilobites, sea scorpions, and many others, all bear chitinous exoskeletons.
The two types of skeleton are not mutually exclusive; an organism can easily have both. The first example that pops into my mind are the ostracoderms, which lived from the Lower Ordovician to the Upper Devonian. These were jawless fishes that had armour on their outside for defence, but also had vertebrae and an internal skeleton.
So, long story short, an exoskeleton is not an invertebrate, nor is it a vertebrate. It does not meet the criteria by which this is determined.
Is a red fox an invertebrate or vertebrate?

Is an earthworm a vertebrate or invertebratate if yes why?
Invertebrate. Earthworms are part of the rank 'Annelida' which translated (From french and eventually Laton) means "little ring". This term described how they are structured -rings or segments.
Quite simply a worm (earthworm) is an invertebrate (lacking vertebra/back bone).
Simple test, cut worm in half, does it have a spine? no? then its invertebrate!
I got this answer by searching 'invertebrate' on wikipedia then did a page search 'earthworm' :D
