Triumphs and disasters in the deep sea This is a journey through time and water, to the bottom of the ocean and the future of our planet. We do not see the ocean when we look at the water that blankets more than two thirds of our planet. We only see the entrance to it. Beyond that entrance is a world hostile to humans, yet critical to our survival. The first divers to enter that world held their breath and splashed beneath the surface, often clutching rocks to pull them down. Over centuries, they invented wooden diving bells, clumsy diving suits, and unwieldy contraptions in attempts to go deeper and stay longer. But each advance was fraught with danger, as the intruders had to survive the crushing weight of water, or the deadly physiological effects of breathing compressed air. The vertical odyssey continued when explorers squeezed into heavy steel balls dangling on cables, or slung beneath floats filled with flammable gasoline. Plunging into the narrow trenches between the tectonic plates of the Earth's crust, they eventually reached the bottom of the ocean in the same decade that men first walked on the moon. Today, as nations scramble to exploit the resources of the ocean floor, The Frontier Below recalls a story of human endeavour that took 2,000 years to travel seven miles, then investigates how we will explore the ocean in the future. Meticulously researched and drawing extensively on unpublished sources and personal interviews, The Frontier Below is the untold story of the pioneers who had the right stuff, but were forgotten because they went in the wrong direction.

A Retriever’s Dream!
Color: Magnolia
This is a great floating bite toy that’s perfect for our water loving standard poodle. The handle and firmly padded body of the toy are perfect for rowdy games of tug of war. The toy is nicely made with bite resistant materials and is holding up to heavy use in and out of the water.

Not for dogs that chew/ Update Seller Stands Behind their Product
Color: Con Leche
My 15 pound cavalier spaniel was in love with this toy, but it only took her about an hour to rip the end of it off and expose the contents. We had to take it away from her to prevent her from eating the inside. It might be good for a dog who only wants to play tug-of-war and not chew -wanted to send it back, but it was destroyed so we threw it in the trash. / As a update, I should have read the reviews and this is not for heavy chewers, I will say the seller was awesome and compensated me for this, thank you Olly!

Dog loves it.
Color: Con Leche
I use this tugger for training only. I use it to ween off treats as a reward as a playful tool. He associates it with this and this way it retains high value.

Nice appearance, lacks sturdiness in the long run
Color: Raven
Decent quality on the surface, but likely to eventually break down with aggressive tuggers or strong jawed dogs. Best for medium drive pups at best.
