difference between homocercal and heterocercal
A heterocercal tail(unequal lobes) is long and thin, for example shark fish.A heterocercal fin has a dorsal lobe that is much larger than the ventral lobe, and the vertebral column extends up and into the dorsal lobe of the fin.
A homocercal tail (equal lobes) has an even groove for example any regular fish.A homocercal fin has equally sized and dorsal and ventral lobes but with a reduced, narrowed vertebral column that supports the fins dorsal most edge.
