Does fish have a neck?
They don't have necks like ours. Instead, they have bones that include a vertebral column, cranium, jaw, ribs, and other bones. The vertebral column (spine) connects to the cranium (skull), so at the base of the skull where it meets the spine is what you would consider the "neck."
Do dolphins have necks?

Which is the only fish with a neck?
Tiktaalik also lacked a characteristic that most fishes have—bony plates in the gill area that restrict lateral head movement. This makes Tiktaalik the earliest known fish to have a neck, with the pectoral girdle separate from the skull.
Do sharks have a neck?
Just Keep Swimming
Nurse and lemon sharks are the exception as they have powerful neck muscles that can pump water over their gills while stationary. Sharks are also only able to move forwards as their fins are stiff and therefore can't be controlled by muscles.

Do sloths have spines?
The three-toed sloth deviates from this rule: many of these tree-living creatures have eight, nine or even ten cervical vertebrae. ... “The 'extra' vertebrae in sloths' necks have the same developmental characteristics as thoracic vertebrae.
