What is the similarity between fish and a man on the basis of skeleton.
Answers
Answer:
This is little more than semi-educated guesswork.
Well - there's a skull and a vertebra in both. And a jaw with fixed teeth, in some species at least. Except the roundmouths, the lampreys- those are jawless but are very primitive designs.. Both fish and humans have limbs. Pectoral fins approximate to arms, ventral fins to legs, caudal fin to our vestigial tail (coccyx). There's no direct human equivalent to dorsal fins.
The skull has orbits for two eyes in each, and passageways for nostrils. And they're made of calcified tissue in humans and in non-shark/ray species.. Both have ribs.
But human bones are load bearing because we live in air instead of water, and are relatively massive as a result.. Fish bones have minimal structure, are mainly anchorage for muscles as most fish have no need of load bearing bones. Both skeletons are highly adapted to the environments their species live in. Fish skeletons are widely diverse according to the kind of specialist life the fish leads. Most of the "round" fish we're most familiar with are generalists in diet and live in relatively shallow fresh or inshore waters over continental shelves rather than open oceans.
As a non biologist that's all that occurs to me.
