Shark grow quickly. They already swim right after hatching and reach adulthood by 15. The longevity of both sharks and dragons are remarkable, but the creature's savage nature means that they are much more prone to die in combat than to die of old age. No half-dragon shark has died of old age so far, but the oldest one ever recorded was 215.

Since bronze dragons are naturally lawful good and shark are unaligned, half-bronze-dragon sharks tend to be somewhere between true neutral and lawful good, but have no set alignment.

Based on the reef shark, the half-dragon is 6 feet long and 3 feet tall. Reef sharks tend to be pretty light, around 30 to 60 lbs, but the draconic appendages and scales bring up the average of the half-dragon to around 120 to 150 lbs. Your size is Medium.

Your base walking speed is 20 feet, as your half-shark fins half-dragon legs are not perfectly suited to land movement. You also have a base swimming speed of 40 feet.

You have a bronze draconic ancestry. You have resistance to lightning and a lightning breath weapon.

You can breathe air and water.

Thanks to your draconic eyes, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray. You also have the shark's innate ability to smell prey around you, giving you the ability to detect creatures within 30 feet of you without using your eyes while underwater. Outside water, your blindsight is based on your draconic ability and is thus reduced to 10 feet.

As a shark, you can't inherently speak, read, nor write Common. As a half-dragon, you can speak Draconic. Draconic is thought to be one of the oldest languages and is often used in the study of magic. The language sounds harsh to most other creatures and includes numerous hard consonants and sibilants.

Your fanged maw is a natural weapon, which you can use to make unarmed strikes. If you hit with it, you deal piercing damage equal to 1d6 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.
