NOVA Season 18 Episode 20 Swimming With Whales

NOVA is an American science documentary television show that has been airing since 1974. It has covered a diverse range of scientific topics, from the mysteries of the universe to the depths of the ocean. In season 18 episode 20, viewers are taken on an underwater adventure as they explore the world of whales.

Titled "Swimming With Whales," this episode provides a fascinating look at these magnificent creatures and the scientists who study them. Whales are some of the largest animals on the planet and are believed to be one of the smartest. They have complex communication skills, can learn new behaviors, and even have their own culture.

The episode begins by introducing viewers to the Humpback whale, a species known for its acrobatic displays and haunting songs. Scientists are interested in studying Humpback whales because they are thought to be among the most intelligent animals on Earth. They have large brains, complex social structures, and can communicate with each other using a variety of sounds.

One of the most exciting parts of the show is when the scientists go out on the water and get up close with the whales. Viewers get to join them in the water and see these creatures in their natural habitat. They watch as the whales breach, spout water from their blowholes, and glide gracefully through the water.

Another species of whale that is explored in this episode is the Sperm whale. These creatures are known for their large heads, which contain a substance called spermaceti. Scientists believe that this substance plays a role in buoyancy and helps the whales to dive deep into the ocean in search of food.

To study Sperm whales, scientists use specialized equipment that allows them to track the whales as they dive deep into the ocean. They can even listen in on the whales' conversations, which sound like clicking noises. By studying these vocalizations, scientists hope to better understand the behavior of Sperm whales and how they communicate with each other.

The episode also touches on the topic of whale hunting. While whaling is illegal in most countries today, it is still practiced in some parts of the world. Scientists talk about the impact that whaling has had on whale populations and how it has affected their behavior.

Overall, "Swimming With Whales" is a fascinating episode that provides a unique perspective on these incredible creatures. Viewers will come away with a greater appreciation for the intelligence and complexity of whales and the important role they play in our oceans. Whether you are a scientist, nature lover, or just looking for an interesting documentary, this episode is definitely worth a watch.
