Why are teleosts so diverse?
It was thought that the genome duplication might accelerate the rate at which the group could modify existing traits and evolve new features, giving them access to new environments or lifestyles. In other words, there was something inherently special about teleosts that gave them remarkable abilities to diversify.

How do neuromasts work?
Neuromasts connect the nerves to the lateral line canal, and that connection through the neuromasts allow fish to sense mechanical changes in water. Each neuromast is comprised of hair cells. Like all hair cells, those of the lateral line are contained in hair bundles.
