New Dental Challenge? Fish with Human Teeth...
Thinking outside the fish tank, while fish with humanesque gnashers swim, there will always be work for Team TDH.
Consider the Sheepshead fish (main picture), not native to our waters, thankfully:
"A fully-grown adult sheepshead will have well-defined incisors sitting at the front of the jaw, and molars set in three rows in the upper jaw and two rows in the lower jaw. It has strong, heavy grinders set in the rear of the jaw too, which are particularly important for crushing the shells of its prey. As with humans, this unique combination of teeth helps the sheepshead process a wide-ranging, omnivorous diet consisting of a variety of vertebrates, invertebrates and some plant material."
Second thoughts, with pristine teeth like this, they wont be needing our help anytime soon.
