Bycatch

Killing whales for food has been happening for millennia. But it was commercial whaling – turning whales into barrels of oil for profit – that led to the wholesale destruction of most of the world’s populations of big whales.

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.

Being a porpoise looks rubbish.

Dolphins look like they have fun. They even look like they seek out fun. Okay, the fixed grins make them seem perpetually happy but let’s be honest - when was the last time you saw a porpoise jumping out of the water or heard a friend gushing about an *amazing* experience seeing porpoises?

There’s good reason that porpoises don’t have the wow factor of dolphins: and it’s not just that they have bad PR people.

If you go down in the deep today, you might get a big surprise. At Hallowe’en the usual ghosts, ghouls and monsters are all-too-familiar. But if you want a real fright, you really need to see what’s lurking in the sea. 

So, prepare yourself as we introduce you to seven of the spookiest, kookiest and most sinister denizens of the deadly deep, deep sea.
