While the term “hybrid shark” might sound like something out of a second-rate horror movie, there’s nothing to fear in this case. The sharks are mixes of two species of blacktip sharks, the common blacktip shark (Carcharhinus limbatus) and the Australian blacktip (Carcharhinus tilstoni).

Some of the sharks were first generation hybrids, meaning one parent was a common blacktip and the other was an Australian blacktip. Others were backcrossed, the result of a hybrid mating with either a common blacktip or Australian blacktip.
Is it possible to breed sharks?
While breeding sharks is a well-intended thought, unfortunately is not possible. Here’s why: Not only do most shark species take nearly a decade to reach sexual maturity, but they also only reproduce every 1-2 years with a handful of pups, completely unlike bony fish.

What’s the difference between a tiger shark and a great white?
Tiger Sharks are all tail. They have a long top tail fin that stretches out behind them and a sleek body that tapers back from the head. Great Whites have a much rounder body with a powerful, symmetrical tail and long pectoral (side) fins.
How do great white sharks procreate?
Great white sharks reproduce through the male inserting one of his two claspers (penises in the shape of a modified pelvic fin) into the female shark’s cloaca. The “process” for shark mating is somewhat similar to what most people are familiar with, although there are a few differences that are worth noting.
What is a dragon shark?
