Deepest living animals in the world

Get the lowdown on the mysterious creatures that live deep down in the murky depths of the ocean.




Deepest diver – The sperm whale

All whales can dive to deep depths but the sperm whale dives deepest of all. They plunge to depths of reputedly 2,500 metres in order to hunt deep-sea squid. To withstand the pressure their lungs and ribcage both collapse and they store the oxygen they need in their blood. They dive roughly the length of a football pitch every minute and can spend around 90 minutes underwater before resurfacing for air. Take a plunge with one and watch the video.


Deepest living fish  – The cusk eel

Cusk eels are actually not eels but a group of very bony fish. They live close to the sea bed in temperate and tropical oceans. An 8-inch long cusk eel was collected from the Puerto Rico Trench.  It was living at the astonishing depth of 29,740 feet - pretty much the height of Mount Everest - only underwater.

Deepest and strangest – The angler fish

Searching for food is difficult when you live in at 3,000 feet below sea level in virtual darkness. Which is why, the anglerfish uses part of its body - a light-producing organ that hangs off its dorsal spine - to lure curious fish to take a closer look.  And when they do, the angler fish will snap them up with its monstrous mouth and swallow them whole!


Deepest eel – The gulper eel

The gulper eel is another bizarre looking creature from the deep. It lives at depths ranging from 500-6000 feet and its most striking feature is its enormous mouth.


Deepest octopus – The dumbo octopus

These charming creatures get their famous Disney name from their paired fins that look like elephant ears. They are the deepest living of all octopus and have been sighted at depths of 7,000 metres.


Deepest diving bird – The emperor penguin

When diving to catch fish, the emperor penguin can reach depths of nearly 900 feet and stay beneath the surface for more than 15 minutes.


Deepest living shark – The goblin shark

These bizarre looking sharks are extremely elusive but can be found throughout the Indian, Pacific and Atlantic oceans. They live close to the sea bottom, at depths of 1200 metres, and feed on crab, squid and fish.


Deep and strange – The chimera fish

These peculiar fish live at depth of 2,500 metres. They are also known as the ratfish, rabbitfish, elephantfish and occasionally the ghost shark.  Which gives you some idea how confusing these fish look like.


Why are whales so big? 

Answer : Firstly, the buoyancy of water helps support their weight. This allows them to grow far larger than any land animal who must support its own weight. Secondly, being big serves a useful purpose when you’re a a warm blooded mammal who lives in very cold water. This is because being big helps decrease heat loss - so a big body means a warm body and whales need to keep warm.
