The painstaking work has an exciting twist as the scientists realise that they might be looking at a 200 million-year-old murdermystery - what fate befell their sea dragon?

This exhibit features the red lionfish, electric eel, lined seahorse, weedy sea dragon and the archerfish.

Look out for weedy sea dragons, pictured, the curious alligator pipefish and delightful yellow seahorses.

Pipefish such as sea horses and sea dragons are specialized on this feeding mechanism.

Instead, habitat loss and degradation due to human activities and pollution threaten weedy sea dragons most.
