Fusion of bones or bones’ fusion? (3)

Last week’s question was:  “Why do we stop growing when we have reached less that a third of our life expectancy?”

Aquatic species such as mollusks, crustaceans, and some fish grow indefinitely.  One giant clam weighed 600 pounds and have been 100 years old; giant squid can grow 50 feet; a giant 2,800 pound turtle has been reported.

The major reason for growth is that the water helps support the weight.  But land-dwelling creatures have to support their bony weight themselves, so their innate intelligence has evolved ways of limiting their size.
