The pufferfish carries a toxin 1200 times more poisonous than Cyanide; it is enough to kill 30 people!
Certain species of fish like sharks and rays need to always keep swimming as they do not possess an air bladder that could keep them afloat
The loudest sound ever recorded was made by an iceberg. In 1997, the sound was recorded and named, "The Bloop." It was said to be heard from more than 3,000 miles away.
Translated from Arabic as the "fish that makes dreams", the Salema Porgy has the ability to invoke vivid, LSD-like hallucinations. Ancient Romans knew this, and actually used the fish as a recreational drug.
Some surfaces in the ocean feature sights that don't seem to make any logical sense—rivers and lakes, some of them miles long, can stretch across the ground even though they're submerged. Water from under the sea floor seeps up and dissolves salt layers, forming depressions. Because the water in the depression is denser than the water all around it, it settles into the depression and forms a distinct pool
When Magellan crossed the Atlantic beginning in 1519, he eventually found his way to another body of water—what he dubbed the Pacific, or peaceful, ocean due to the calm surface. He didn't know it at the time, but the Pacific would eventually be recognized as the largest ocean on the planet at 59 million square miles.
You can find the Yeti Crab near thermal vents in some of the coldest parts of the ocean. There, they live in a precarious position: move too close to the vents and they will instantly fry; move too far and they can die of hypothermia. Their "fur" is actually blonde setae, bristles that enable them to harvest their main source of food: bacteria. They dance around, waving their claws through the water to get a constant flow of oxygen and grow the bacteria they subsist on.
The global ocean conveyor belt, responsible for the constant movement of water around our oceans, moves much slower than wind or tidal driven currents. It is estimated to take a parcel of water up to 1000 years to complete a full cycle around it! It is also constantly moving over 100x more water than the Amazon River.
The eviota sigillata, or more commonly known as seven-figure pygmy goby and adorned dwarfgoby lives its entire life on average 59 days. Three weeks as larvae, two weeks to mature, and a little over three weeks to reproduce. Meaning that current generation has died today or are going to die soon and the next generation will begin.
Point Nemo' in the Pacific is the furthest point in the ocean from land, located over 1,000 miles from any landmass. Quite often the closest humans to this point are the astronauts on the International Space Station as they pass overhead.
