Our Blue Planet is Talking About our Oceans!

Contributed by Gina Carter

BBC Earth and OceanX Media have brought us amazing stories from below the surface of our oceans that have shocked, amazed, and interested us. For World Oceans Day, we are talking about #OurBluePlanet and a couple of interesting stories, in hopes to entice more girls to consider careers in the marine sciences.

Footage gathered by placing cameras on animals has allowed scientists the ability to study these mysterious creatures closer than ever before.

Sperm whales are a multicultural community with neighboring families and lives not unlike those of humans. These cameras were specially designed to withstand the pressure of the depths of the ocean and allow scientists to see life in the deep. These scientists have been able to learn about the calls between whales within a pod and to better understand how they recognize and respond to one another.

Sperm whales are at risk and one in three babies will not survive past the age of one. Because of this, scientists are trying to better understand whale culture and how they interact with one another, to try to protect their population.

A Deep Sea Octopus Tended to her Eggs for 53 Months

The deep sea octopus, Graneledone boreopacifica, has been known to have some of the largest offspring, but no one knew exactly how long the mother octopus brooded over her eggs. In warmer waters, octopi are hatched in about 1 to 3 months, but deep sea octopi had not been studied.

When a group of researchers happened upon a brooding octopus, they took note and continued to revisit the site to determine the length of time of brooding.

As they continued visiting month after month, they saw the mother’s condition deteriorate. Mother octopi do not leave their eggs to feed and thus they eventually die of starvation. Finally, after 53 long months, or 4.5 years, they returned to find all the eggs hatched and the mother gone.

This sacrifice by the mother leads to high survival rates for the young octopi as they are larger and have an advantage over predators.
