CALIFORNIA SEA LIONS! [Zalophus californianus] This is some of what was going through my mind: What a wild and triumphant experience swimming with these fun and playful marine mammals. I hope you get a sense of their agility and inquisitiveness and their effortless movements. My team had to practically drag me out of the water when it was time to move on (stay tuned for what we moved on to...) Sea Lions are magnificent animals and one of the most playful mammals. They displayed all of their aquatic acrobatics here in the shallow waters surrounding this island in the Sea of Cortez. Darting, diving, twisting, blowing bubbles, they seemed to be flying more than swimming. Other than marveling at their movements and playfulness, I couldn't stop thinking about their keen hunting and perceiving adaptations, namely their hydrodynamic sensors called vibrissae (whiskers). Evolution has honed these super sensors to be able to detect water flow and movement. They have extraordinary sensitivity, allowing them to detect the water wakes and tiny vortices left behind by fleeing fish. These specialized mechanoreceptors even reduce interference from the sea lion's own swimming, allowing them to detect the subtle hydrodynamic trails left by prey. All pictures were taken at The Vermilion Sea Institute and Rancho San Gregorio during Miami University’s Project Dragonfly Baja Earth Expedition.

Wild Peruvian Amazon Rainforest Creatures of the Night!
This was unbelievable, and possibly the most wonderful and awe inspiring nature events of my life! Filmed just off the coast in Santa Rosa Beach, Florida, this 4K drone nature film captures a superpod of bottlenose dolphins moving through clear blue Gulf water. I spent close to an hour filming these amazing dolphins (used up two batteries). It was endless awe and fascination watching these wild and playful behaviors unfold in crystal clear emerald water. I did my best to follow and track the pod - it was a fun and challenging task! The group includes both adult dolphins and babies, with nearly 100 dolphins swimming, splashing, leaping, and playing together in one of the most beautiful wildlife scenes I’ve ever seen. Bottlenose dolphins are highly social marine mammals. Their groups often shift and change, a pattern scientists describe as a flexible “fission-fusion” social structure. NOAA notes that bottlenose dolphins may travel alone or in groups, and those groups often break apart and come back together over time. Check out the many behaviors in this video: fast swimming, upsidedown swimming, synchronized movement, leaping, splashing, and breaching may serve several purposes. In dolphins, aerial behaviors can be connected to play, communication, coordination, social bonding, and sometimes feeding or travel. This film is a reminder that the Gulf of Mexico is ALIVE! with complex animal behavior, family groups, communication, and wild intelligence. Filmed in 4K60 and edited in slow motion for a meditative and peaceful view of dolphins along Florida’s Emerald Coast.

THANK YOU to all the wonderful AP BIO All-Stars who helped make this video, I am grateful for your help and inspiration! To the students who have made my job so great over the past 28 years - Thank you. And I'm eternally grateful to my teachers and my teacher friends and colleagues. This video is an attempt to showcase the beauty of AP Biology and help promote the class. In this video, you’ll get a real look at what AP Biology is all about: from hands-on labs and student experiences to guest speakers and real-world applications of biology. AP Bio is an engaging, lab-based course focused on understanding the world around us and within us. This class is designed for curious and motivated students who want to challenge themselves, think deeply, and learn how to learn. You’ll hear from current and former students, as well as professionals in science and medicine, about how AP Biology has impacted their thinking, education, and careers. If there is something you think would be a good addition or something we left out or if you have questions - please leave a comment. The real ROI (Return on Investment) of taking AP Bio is this: Spending a year exploring nature with like-minded, curious, hardworking, caring, and bright students. HELPFUL LYNX: EARN COLLEGE CREDIT!

Before you take AP Biology you'll want to have already taken high school biology and chemistry. 2. You'll want to be a strong and curious student, with strong reading, reasoning, and teamwork skills.
