Educational Sperm Whale DVD

In order left to right: The size of a sperm whales' tooth is comparative to the size of a Chiwawa dog, and the biggest of all the animals.

This illustration of a circle of adult whales around a calf is to mirror the narration explaining how Sperm Whales' only natural predator is the Killer/ Orca whale. Although possible, adult sperm whales are often too difficult to kill due to their size, so Orca's try to seperate the calf from the group as it is an easy target. The correct terminology for this circle is a 'rosette' which is formed to prevent the Orca's from reaching the calf. This was actually used in the DVD in the end as we were making something more specific to the Mediterranean where there are no Orca's. Their only threats here are anthropogenic.

Echolocation - Diagram showing the process of sending out sonar waves to detect food and location (and threats).

Food - Showing how the sonar works, bouncing off an object and back to the whale, with the whale sometimes being able to tell what the object is from the pattern of the returning sound waves.

Whale pods - Male and female Sperm whales live in separate pods, and even in different geographical locations. The females help each other to give birth and look after the other calves when mothers have to leave the surface to hunt for food. When male calves reach a degree of maturity – after 4 years old – they join the male group. They return to reproduce when they reach their twenties, then doing so every three to six years.
