Orange roughy are easy to over fish. So, humans do. But that doesn't seem to be stopping moves to re-define them as 'sustainable' by the Marine Stewardship Council.

True, when we started fishing orange roughy we didn’t know that this slow-growing, long-lived, deep water fish was particularly susceptible. But now we definitely do. Orange roughy can live to a staggering 150 years old, and are at least 30 years old before they are mature enough to breed. To put that into context: there are probably orange roughy alive today that were born when Queen Victoria was on the throne, and they take about 10 times longer to mature than Atlantic cod.

Imagine becoming a parent at the age of 65. It might seem miraculous but that is what has happened to the world’s oldest known wild bird, an Albatross living on an island in the middle of the Pacific Ocean.

The New Year’s storms have brought a lurid, unmissable reminder to UK beaches, with thousands of bright pink detergent bottles being churned up by the sea. As waves of highly-visible plastic trash hit British beaches, it’s a timely reminder of a much bigger problem: we are turning our oceans into plastic soup. It’s been estimated recently that about EIGHT MILLION TONNES of plastic ends up in the ocean each year.

Tuna are fish, and they are wild animals. But to many people, they are simply understood as food. It can be a bit confusing when the short hand of ‘tuna’ is used, as it covers a whole family of species, from the relatively-tiddly and widespread skipjack, right up to the majestic but beleaguered bluefins.

Still no contact as yet between our ship Esperanza and the Japanese whaling fleet as the Espy heads further and further south on her mission to save as many minkes as possible from the whalers' harpoons. She's passing through some of the most glorious and unpolluted seascapes this world has to offer at the moment, though, and our photographers have been out and about in inflatables to capture the magic, so I thought I'd share a few with you.

Wow factor: In this shot it's hard not to be impressed by the sheer size of this ice cliff rising almost verically out of the sea.
