If two animals share the same environment, then at some point they are likely to meet. In the wild these meetings are often between predator and prey; however, nature isn’t always so cruel. Some such encounters, referred to as “interspecies interactions,” can be playful or social, where neither individual is threatened.

Pacific Whale Foundation Hosts Annual “Be Whale Aware” Lecture

Each winter, an estimated 10,000 humpback whales migrate from Alaska to Hawai’i to mate and give birth.  In Hawai’i, humpback whales are engaged in important social and behavioral activities. Approaching whales  too close or fast may disrupt these behaviors and cause unnecessary stress to the animals.

In order to promote responsible whalewatching, Pacific Whale Foundation developed the “Be Whale Aware” guidelines. These guidelines build on current federal and state regulations, as well as scientific research.

What do Whales and Cats have in common?

Marine mammals have a reflective layer behind the retina of their eye called tapetum lucidum, which is Latin for “bright tapestry”. It is this same reflective layer that causes the eyes of cats to glow at night. This layer enhances the ability of an animal to see under low light conditions by reflecting light back through the retina a second time, making the most of available light.

The retina of baleen whale’s eyes contains mostly rod cells, which are sensitive to low intensity light, while cone cells, which distinguish between different colors and are most sensitive to bright light, are less abundant. This means that whales are most likely to see the world in shades of grey.
