For many people, seasickness is the most unpleasant thing that happens to them at sea. Beneath the surface of the sea, however, is a whole other world, a lot of which could turn all but the strongest stomachs.

But disgust is actually pretty irrational, when you think about it. Someone who is disgusted when they see a dead bird lying by the side of the road can perfectly happily drive home and eat another dead bird for dinner.

Once upon a time, before the days of best before or use by dates, we relied on our own senses to tell us when food was good to eat. Disgust is a primitive defence mechanism designed to make us avoid bad food before we put it in our mouths or to vomit it back up if its already too late.

Feelings of disgust come from the primal part of the brain that warns us of danger, even when the logical side of our brain tells us theres nothing to be worried about. In this way, disgust is nowadays about as rational as any other phobia.

You probably wouldnt want to eat many of the species featured in How to Snog a Hagfish!, but plenty of people around the world do! Reading this book might not make you want to join them, but understanding how and why these amazing creatures have developed the way they have may make them seem just a little less disgusting. Or of course it may not.

If you are a fish the size of a pencil in an ocean full of sharks the size of trucks, you probably shouldnt expect to die of old age. If you are lucky, you were born with the ability to defend yourself, preferably with poison (see ). If you are unlucky, you might have to rely on your appearance, and hope other creatures in the sea think you look distinctly unappetising.

Many people consider the Blobfish to be the ugliest creature in the sea. Indeed, Blobfish is an appropriate name for an animal that consists mainly of a jellylike substance. It has hardly any muscles and cant really swim. Instead, it just floats about wherever the currents take it, buoyed up by its jelly body, which has a similar density to seawater. Of course, not being able to swim very far, it cant hunt for food either. So it just eats whatever drifts past, from small molluscs to smaller fish. Fortunately for the Blobfish, just floating about doesnt use up much energy, so it doesnt need to eat much either.

Living off the coast of Australia at depths of about 2,600ft (800m), the Blobfish is rarely seen by humans. When caught in a fishing net and brought to the surface, the Blobfish quickly dries out in the air and pops. It makes quite a mess. But perhaps the real reason we find it so disgusting is because, looking at it head on, the Blobfish bears more than a passing resemblance to a very ugly (and miserable) human face.

The American Anglerfish isnt nicknamed the All-mouth without good reason it has one of the smallest mouth-to-body ratios of any fish, with its mouth being at least twice as wide as its tail. Living at depths of up to 3,300ft (1,000m), as some Anglerfish do, you need a big mouth to take big bites. Just ask the Umbrella Mouth Gulper Eel (see ). Food can often be scarce, and fish that nibble slowly at their dinner risk losing the meal (and maybe their own lives) to scavenging predators that can swallow things whole.

Some types of Anglerfish have a light-up lure to attract their prey (you can read more about fish that go fishing on ). Some of the larger types that can grow to 5ft (1.5m) visit the surface if they get hungry, and will grab seabirds that are floating there, taking a breather from flying. Many people probably wouldnt eat an Atlantic Anglerfish if it was served up whole, but a lot of people do in fact eat it and love it, because by the time it is filleted, sliced up and shipped to supermarkets it is called Monkfish or Goosefish instead.

The Stomiids also live in the murky depths, with various members of the family living 2505,000ft (76.21,524m) down. With common names like Dragonfish and Viperfish, what makes the Stomiids so off-putting are their spectacular teeth. Their jaws would surely be enough to make even a shark think twice (though not all sharks are renowned for their intellect). The Dragonfish has a mouthful of fangs that are as sharp as a knife, and if that isnt enough, it also has teeth on its tongue. The Viperfish has barbed bottom teeth so long they cant fit in its mouth, and it needs to use its own backbone as a sort of shock absorber to cushion the impact when it snaps its jaws shut on some unsuspecting prey.
