DEEP-SEA FACTS

The most unexplored and giant habitat on Earth , that is "THE DEEP SEA" , which covers almost 95 percent of Earth's living space. Yet , the deep also being one of the most amazing places on the planet. Throughout this blog we'll explain six amazing interesting facts about the deep sea , lets go and read it below:-

Deep Sea Facts

1. Nobody knows where it begins

The deep sea is a contested term lacking a single exact definition , for some it refers to any part of the ocean where scary , odd and downright bizzare creatures live for others it's a descriptive definition of specific ocean depth . some claim it to begin at the edge of the continental shelf where sunlight typically starts to fade a depth of usually around 200 metres others such as the world register of deep-sea species instead regards it as any point at which seasonal variations in physical parameters such as temperature becomes minimal , this means that the deep-sea is usually anywhere below 500 metres however as the average ocean depth is around 4000 metres others would argue that the deepest depths are below 1000 fathoms or 1828 metres , at this depth as temperature come close to freezing and little or no sunlight is present for photosynthesis a very few creatures are able to exist using light , pressure and thermal interfaces , oceanographers have divided the ocean into five distinct layers which can vary depending on the area and clarity of the water as each zone is distinguished by their unique characteristics.

2. Deep-sea creatures are purposefully incredibly diverse 

Species from the deep may look like they have evolved in strange ways just to freak us out but in fact they have evolved that way for specific survival purposes for instance ,  to take advantage of the lack of light most animals are transparent or red in color which few creatures can detect and is camouflaging in the darkness for those in the shallow deep sea enormous eyes take advantage of what sunlight exists and bioluminescence a chemical reaction that allows animals to create light is thought to be a way of counter illuminating faint sunlight from above so that fish are visible to predators below them given the amount of water above them pressure is another element creatures from the deep must deal with it's enough to distort the complex molecules membranes and proteins upon which all life depends that is why the deepest sea creature are often gelatinous with very minimal bone structures again to survive in the cold waters which can go below zero due to the salt in the water , many creatures carry highly unsaturated fats in their cell walls which help them to maintain the membrane fluidity in freezing cold depths of the ocean.

3. Exploring the deep-sea is tremendously testing

It is an obvious fact but one of you probably haven't seriously thought about part of the reason why it's taken us so long to explore is because only recently have we created new generations of incredibly sophisticated underwater vehicles that are able to venture so deep , some of the many submarines  we have created are still often defeated by the waters crippling pressure as even the most advanced research vehicle in operation in 2014 imploded whilst in operation at the time it was crushed under 10,000 metres of water , scientists estimated that there was about 16,000 pounds per pressure on the craft to prevent crafts from imploding submersibles must be internally pressurised to equal the pressure exerted from the outside , so it's fair to say that these machines are pretty amazingly engineered , not only must dep-sea researchers battle with some of the toughest elements , they must cope with the issue of being seriously underfunded space exploration , dollars seriously dwarf ocean spending as seen from US fiscal spending in 2013.

4. How many people have been gone into deep-sea?

Only three people have ever been to the deep sea due to the previously mentioned extremities , the deep sea may be the final frontier of exploration , many more people have been into space than to the deep sea like seriously a load moreover 500 people have been into space whereas only three people have ever ventured over 1000 fathoms into the depths of our ocean , the first two people to venture deep , really outdid themselves and descended to the bottom of the deepest known part of the Earth's seabed. In 1960 they descended into what's known as the challenger's deep which is a relatively small slot shaped depression in the Pacific Ocean that resides , already unusually deep Mariana Trench , the third person to venture into the deep sea went there in 2012 and first showed enthusiasm for the deep by directing and producing movies like The Abyss and Titanic James , Cameron unsatisfied with the lack of deep-sea exploration spent a reported ten million dollars to fund the construction of his deep sea challenger vessel , he descended to over 11 kilometres where he spent three hours collecting scientific data , specimens and visions unthinkable in 1960.

5. Discovery of new species

New species are being discovered daily , since it's largely unexplored each time a vehicle is sent into the deep it's highly likely to unearth a new discovery over a recent year long period , the world register of marine species reported discovering 1451 new marine species of which many were found to be from the deep sea , that means on top of the 240000 marine species already recorded ,  roughly four new species are found daily which is astonishing considering that over a deacade ago , many scientists assumed this to be the upper limit revised estimates based on the current rate of discovery suggest that we only currently know about a quarter of ocean species in existence , although many scientists think we know even less than this conidering that most of those species of the deep , of which the world register of deep sea creatures has only recorded twenty thousand so far , there are many more crazy species we're yet to find.

6. It's a giant playground

The term deep sea gigantism exists in zoology for a reason , it refers to the tendency for deep sea dwelling animals to be larger in size than their shallow water relatives , we're not sure whether it comes about as a result of adaptation for scarce of resources , greater pressure or for other reasons , however in the case of marine crustaceans it's been proposed that trends involve increasing size and age with decreasing environmental , ten here a few examples of this phenomenon The Giant Isopod , The Giant Amphipod , The Japanese Spider Crab and a Giant Squid. Just imagine what other giants lurk in the depth it's a scary thought when you consider , how little we have explored of the deep sea.
