It is a significant find that will aid in the understanding of commerce and trade routes in the ancient world, around 218-210 B.C.

Jarrod Jablonski, president of GUE, said the find was a “remarkable piece of history”, exhibiting intricate wave patterns and Greek letters inscribed into its surface. Sixteen other unique artifacts were recovered by GUE technical divers working closely with submersibles from Brownie’s Global Logistics. The Sicilian government will study and preserve these artifacts.

Chris Avila, of Canadian Marine Aquaculture, described how he was trying to collect a 3mm DNA sample from each of the fins of a new shipment of sharks, a species of bamboo shark (Hemiscyllium halmahera).

They showed no signs of distress when handled and had not reacted to having their fins pinched lightly, which is a stress test done prior to the clipping. Nevertheless, Avila had lightly sedated them for the procedure.

During the battle between the French and the Dutch, who controlled Tobago at the time, the French flagship Glorieux, with her superior guns, sank the Dutch vessel on 3 March 1677.

Kroum Batchvarov, assistant professor of maritime archaeology and leader of the research team, said: “To find the Huis de Kreuningen—almost by accident, as she was outside the boundaries where we expected to find her—undiscovered and untouched for over 300 years was an exciting moment.”

The present study examined shark distribution patterns, species-habitat associations, and marine reserve use with baited remote underwater video stations (BRUVS) along the entire Great Barrier Reef Marine Park (GBRMP) over a ten-year period.

Overall, researchers recorded 21 different shark species. The relative abundance of sharks was significantly higher in non-fished sites in the GBR Marine Park no-fishing zones relative to fished sites.
