Have you ever wondered what it’s like to explore the ocean’s depths? Peter Croc, an international cinematographer, does just that by capturing the wonders of the underwater world. Even when he’s close to home in California, he’s out filming the amazing marine life that lives beneath the waves.
To film underwater, you need to be a skilled diver and have lots of patience. Sea creatures don’t follow instructions, so you have to wait for the perfect moment to capture them on camera. Some of the best diving spots are right off the coast of California, where you can explore underwater forests made of kelp.
The kelp forests off California’s coast are like underwater jungles. Here, you’ll find rocky areas, schools of fish, and a variety of marine mammals like seals, sea lions, dolphins, and even whales. The ocean is full of life, from tiny creatures to the occasional great white shark. You don’t have to go far to see these amazing animals.
One of the most common creatures in these waters is the giant green anemone. Although they look like flowers, they’re actually carnivorous animals. They live in shallow waters where the sunlight is strong, and their green color acts like sunscreen. These anemones can live for up to a hundred years!
Anemones are territorial and stay in one place, defending their area by stinging. When underwater, they look much larger than when exposed to air. During low tide, they can be out of the water for hours, managing this by expelling excess water. Some anemones stay in the same spot for over 50 years.
Another interesting creature is the sand dollar. When you find them on the beach, they’re usually dead and look like white coins. But in the ocean, live sand dollars are covered in tiny spines and use tube feet to move slowly across the sand. If you look closely, you can see trails in the sand showing their movement.
The purple sea urchin is another resident of the California coast. It’s spiky and more aggressive than the sand dollar. Sea urchins have a unique mouth structure called a lantern, which they use to eat kelp. Sometimes, they eat so much kelp that it creates areas with no kelp at all, called urchin barrens. Since they can live up to 70 years, this can cause long-term changes in the ecosystem.
Some sea creatures are harder to film, like the Pacific hagfish, which lives deep in the ocean where humans can’t go. Peter had the chance to film these fascinating creatures, which look like eels but are actually jawless fish. They feed on anything that falls to the ocean floor, like whale carcasses, playing an important role as scavengers.
The marine ecosystem off the California coast is incredibly diverse, with each species having its own special role. From the colorful anemones to the mysterious hagfish, every creature is fascinating in its own way. Thanks to Peter’s work, we can all enjoy the beauty and wonder of this underwater world.
Imagine you’re an underwater cinematographer like Peter Croc. Use a shoebox to create a diorama of the California kelp forest. Include marine life such as fish, sea lions, and anemones. Use materials like clay, paper, and paint to bring your underwater scene to life. Share your diorama with the class and explain the roles of the creatures you’ve included.
Choose one of the marine creatures mentioned in the article, such as the giant green anemone or the purple sea urchin. Research its habitat, diet, and role in the ecosystem. Create a poster or digital presentation to share your findings with the class. Highlight interesting facts and why this creature is important to the underwater ecosystem.
Imagine you’re capturing the beauty of the ocean like Peter Croc. Use a camera or smartphone to take photos of nature around you, focusing on details like color and texture. Create a photo gallery to display your work, and write captions explaining what inspired your shots. Discuss how these skills could be applied to underwater photography.
Participate in a role-play activity where each student is assigned a role as a different marine creature from the kelp forest. Discuss how each creature interacts with others and its role in the ecosystem. Consider the impact of changes, such as the creation of urchin barrens, and how it affects the balance of the ecosystem.
Design a poster to raise awareness about the importance of conserving the California marine ecosystem. Include information on threats to marine life, such as pollution or overfishing, and suggest ways people can help protect these underwater habitats. Display your poster in the classroom or school to educate others about marine conservation.

[Music] Peter Croc is an international cinematographer who captures the natural world in unique ways. Even when he’s closer to home, he’s out filming. [Music]
To be an underwater cinematographer, you need to first be a good diver. You also need to have a good amount of patience. Animals don’t always react well to instructions, so you often have to wait for them to do their thing. Some of the best diving in the world is actually right here off my doorstep in California. If you get a good day in the California kelp forest with good visibility, it’s amazing—like diving in an underwater forest. [Music]
We have rock outcroppings and kelp forests, schools of fish, deep and shallow areas, and a variety of marine mammals, including seals, sea lions, dolphins, and whales. We basically have a little bit of everything. There are predators of all sizes, from microscopic creatures to the occasional great white shark. You don’t have to go very far out to see some of these animals. [Music]
One of the most common creatures along the California coast is the giant green anemone. They may look like flowers, but they are actually carnivorous animals. The anemone often lives in shallow water where the light intensity is stronger than in deeper waters. To protect themselves from the light, they have developed a green pigment that acts like sunscreen. They are resilient creatures and can live up to a hundred years. [Music]
Anemones are quite territorial and don’t move around much. They defend their area using the same technique they use to catch prey: they sting. An anemone underwater appears much larger than one exposed to air. At low tide, they can be exposed to the sun and air for several hours, and they manage this by contracting and expelling excess water. Green anemones can stay in the same spot for over 50 years.
Another animal we have here in California that people sometimes encounter on the beach is the sand dollar. When we see it on the beach, it’s typically dead and has lost its spine, appearing white and somewhat like a silver dollar. Live sand dollars in the ocean are covered in tiny spines and have tube feet that they use to move over the sand. [Music]
When you dive down and see sand dollars, they may look stationary, but if you look more closely, you can see trails behind them indicating movement. They move so slowly that it’s hard to notice, so I’ve used time-lapse photography to speed up the process. Once sped up, you can see that they are quite active. Sand dollars have small, harmless spines, but another resident of the coastal community is the purple sea urchin, which is spiky and more aggressive.
The purple sea urchin has spines, tube feet, and a unique mouth structure called a lantern, which consists of five tooth-like structures used for eating kelp, their main food source. Sea urchins can exert tremendous pressure on kelp forests, and sometimes we experience urchin barrens where all the kelp is gone. Since sea urchins can live up to 70 years, this can lead to long-term ecological issues.
Peter knows where to find sea urchins, but some sea creatures off the California coast are a challenge for even the most experienced underwater cameraman. The Pacific hagfish lives at depths where no human can safely go. He had the extraordinary opportunity to film these complex and rarely seen creatures. [Music]
These hagfish were collected by Scripps for research, allowing me to film an animal that normally lives at depths of four to six hundred feet, which I can’t access. The hagfish resembles an eel but is actually a jawless fish and is an ancient species. They feed on anything that may fall into the deep water, such as whale carcasses. Whether they look appealing or not is subjective, but their role as scavengers is important. Every animal in the ocean has its own niche, and each is uniquely fascinating, especially when viewed through Peter’s expert lens. The California marine ecosystem is incredibly diverse, with countless species, each a master of its own area. As long as I can get up, put on a tag, and get in the water, I’ll be out there filming.
