A daily intake of approximately 4 tons of krill equates to about 3 million calories for the blue whale, the earth's largest creature.

This is a stark contrast to the mere 2,500 calories an average human requires. This comparison alone offers a glimpse into the blue whale's impressive lifestyle and biology that we will explore.

We'll also delve into the best conservation methods for this species and discuss why its size defies typical mammalian norms.

All creatures are bound by time, yet their lifespan is dictated by their genetic and epigenetic makeup. The leatherback turtle is a prime example, armed with sophisticated survival strategies that defy time and mortality.

Discover where they hatch, their diet, their behavior, and how their exceptional ability to regenerate could provide invaluable insights for us.

The topic today is the oarfish, this strange odd-looking fish that seems to come straight out of a Jules Verne novel.

Discover why exactly this fish is extremely sought after by professional divers and scientist around the globe.

In addition to explaining its stunning biology, bioluminescence and size, this fish has a very special relationship with earthquakes and you will se how.
