In the open ocean around the Bahamas, pods of wild Spotted Dolphins frolic in the sunshine. Sometimes, they get bored and approach boats. In this educational video, Jonathan joins dolphin expert Wayne Scott Smith to learn how dolphins interact with each other. Jonathan learns how to play the Bandana Game, a game of -keep away- that the dolphins invented and like to play with Scott. Please see the accompanying study guide for educational objectives and discussion points.

Bycatch can be defined as the act of unintentionally catching certain living creatures using fishing gear. A bycatched species is distinguished from a target species (the animal the gear is intended to catch) because it is not sold or used. Marine mammals (whales, dolphins, porpoises), seabirds, sea turtles and unwanted or undersized fish are some examples of animals caught as by-catch The incidental capture of these animals can significantly reduce their populations. The most well known example of by-catch may be the unintentional mortality of spotted and spinner dolphins in the tuna fishing industry. "Dolphin-Safe" tuna was a result of this interaction (Be prepared to discuss how this came about with students, as it is something close to their daily lives). One important aspect to consider when discussing this issue is that laws protect some of the animals caught as by-catch (Marine Mammal Protection Act and Endangered Species Act). In this lesson, students will first be shown pictures of entangled marine animals and will discuss the definition of by-catch This will lead to discussions on why by-catching exists, how it impacts specific animals as well as humans, whether the students believe it is an important issue, and how by-catch can be reduced.

This educational video features Sperm whales and has an accompanying lesson plan to teach about Sound in the Sea. The Sperm whale holds many records. It is the deepest-diving whale on Earth, the largest toothed whale on Earth and has the largest brain on the planet too. On top of that, it has a reputation for being a vicious beast, thanks in part to Herman Melville's Moby Dick. But the real Sperm whale is a lot different than people think. It has a highly-evolved social life, operates at depths where nobody can see them most of the time, and uses sonar which is so sophisticated that it makes the Navy's electronics look like toys. Sperm whales are very hard to find and even harder to film. In the Caribbean, Jonathan repeatedly attempts to get close to the elusive whales, until finally he succeeds and has an incredible experience eye to eye with a giant who investigates him with powerful sonar clicks. Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.

This online textbook chapter will provide students with an understanding of the mourning behaviors in animals. It explores the different definitions used to compile the data today and provides examples across a variety of species including non-human primates, crows, elephants, dolphins, and whales. Multiple studies are cited which aim to collect first hand observational data as well as data analyzation from a variety of perspectives around the globe.

Echolocation is the ability to orient by transmitting sound and receiving echoes from objects in the environment. As a result of a Marco-Polo type activity and subsequent lesson, students learn basic concepts of echolocation. They use these concepts to understand how dolphins use echolocation to locate prey, escape predators, navigate their environment, such as avoiding gillnets set by commercial fishing vessels. Students will also learn that dolphin sounds are vibrations created by vocal organs, and that sound is a type of wave or signal that carries energy and information especially in the dolphin's case. Students will learn that a dolphin's sense of hearing is highly enhanced and better than that of human hearing. Students will also be introduced to the concept of by-catch Students will learn what happens to animals caught through by-catch and why.

In this video, Jonathan travels to Holbox, Mexico in search of the massive whale shark‰ŰÓthe world‰ŰŞs largest fish. Reaching 50 feet long, these animals grow larger than a school bus, but they are completely harmless since they eat only plankton and small fish. Jonathan gets up close and personal to a mouth the size of a small car in his investigation to discover why so many whale sharks visit Holbox every summer. Please see the accompanying study guide for educational objectives and discussion points.
