Do all mammals have seven neck vertebrae?

How many neck bones do sloths have?
But almost every placental mammal on earth (some 5,000 species in total) has seven 'ribless' vertebrae in the neck – even creatures with long necks such as giraffes. The three-toed sloth deviates from this rule: many of these tree-living creatures have eight, nine or even ten cervical vertebrae.

The superior articular facets look like moose antlers, while the purportedly “hatchet-shaped” spinous process is inarguably a large, clunky moose nose.
Does camels have 7 cervical vertebrae?

How many bones does a giraffe's neck have?
Despite its elongated form, the neck of a giraffe is made up of just seven large bones known as cervical vertebrae. By comparison, the body of the common house mouse (Mus musculus) is only around 10 centimetres long, its tail contributing more to the overall length.
Do dolphins have necks?
Dolphins have non-flexible necks, limbs modified into flippers, non-existent external ear flaps, a tail fin, and bulbous heads.
Which animal has the most neck bones?

Is a sloth a mammal?
Sloths are mammals, but they aren't primates or marsupials – though the groups do share some similarities. Koalas, for example, are marsupials that live in trees, eat leaves and have slow metabolisms. But sloths and koalas developed these traits independently of each other.
How many neck bones does a camel have?
Complete answer: The number of cervical vertebrae is the same in all mammals and the number of remaining vertebrae differ which depend on their body structure. In camel cervical vertebrae is 7, thoracic is 12, lumbar 7, sacral 5, and caudal is 15-20 in number.
What animal has no neck?
Fish have fins and gills, but they don't have necks. That's partly because it would be difficult to swim quickly with a neck that wagged back and forth in the water. What's more, anything called a fish, by definition, can't have a neck.
What animal has the shortest neck?
Only the Giraffe (and its rain forest relative, the Okapi) have necks that are so short relative to their legs and chest that they must splay or bend their legs. So why has the Giraffe not become famous for it's short neck?
Are sloths vertebrates or invertebrates?
What kind of animal is a sloth? Sloths are mammals. They are part of the order Pilosa, which is also home to anteaters.
