JENKINSON'S AQUARIUM Call for feeding schedules of the penguins, alligators and Atlantic sharks.

The milk shark likely once had a contiguous distribution by way of the Tethys Sea, until during the Miocene epoch, when eastern Atlantic sharks were isolated from Indo-Pacific sharks by the collision of Asia and Africa.

This suggests that Indo-Pacific blacktip sharks are descended from those in the eastern Atlantic, while the western Atlantic sharks became isolated by the widening Atlantic Ocean on one side and the formation of the Isthmus of Panama on the other.

Apart from some agreements between the EU and Norway there are no international catch limits on north east Atlantic sharks.

Since 1999, retention of this species has been prohibited by the U.S. National Marine Fisheries Service (NMFS) Fishery Management Plan (FMP) for Atlantic sharks.

Eastern Atlantic and Indian Ocean sharks seem to match or exceed the size of northwestern Atlantic sharks, but the figures are based on relatively few individuals and more data is needed.
