ALL WHALES are able to dive to great depths, but the sperm whale can dive the deepest of all.
huge marine mammals plunge 2500m into the ocean to hunt deep-sea squid.
To cope with the enormous pressure they are under at these depths, their lungs and ribcage collapse and they store oxygen in their blood.
They can spend about 90 minutes underwater before resurfacing to breathe. -
