When the sperm whale rises to the surface, markings can often be found on and around the sperm whale’s head, which appears to be caused by battles with the giant squid they are trying to consume.Ĭompared to the colossal squid, these marine mammals eat adult sperm whales that can grow to lengths over 50 ft. In these situations, it appears that the giant squid latches onto the sperm whale’s head with its tentacles to avoid being eaten. While researchers haven’t been able to witness any battles between a sperm whale and colossal squid (which can measure in at over 45 ft and weigh more than 1 000 pounds), the markings found on the sperm whales head indicate struggles they’ve had while trying to consume this species of squid. It allows the sperm whale to maintain an abundant food source without interruption from other animals, even those that live in deep waters.Īs stated earlier, most of what is known about the sperm whale’s squid diet has been studied from the contents of the sperm whale’s stomach. In addition to having prey that lives well beyond the threats of humans and other marine mammals, giant squid rarely has any predators in the deep waters that they live in. They do not have to worry about their food being captured by fishermen or other marine mammals. However, their primary diet consists mainly of squid, and since they eat food that lives in reasonably deep water. Sperm whales eat giant and colossal squid, octopus, cephalopods, cuddle fish, and various other fish. However, stomach content and rare observations have given us some idea of what the sperm whales’ typical diet looks like. While some information has been uncovered regarding these excellent hunters’ diets, their hunting methods have not been well researched due to the deep dives these whales make when hunting for food.īecause of their ability to travel so far underwater, studying or recording their behaviors has been difficult. However, most of the time, their dives are usually no more than 2,600 ft. This marine mammal can dive over 6,000 ft. She grew up bilingual in German and conversational in French.The Sperm whale is the deepest diving marine mammal in the world. Away from her pen, Erika runs, skis and enjoys all things ocean and outdoors. She's won many first-place awards from the Los Angeles and Orange County press clubs. Ford Foundation has awarded her coverage of National Defense. She's a three-time award winner from the Marine Corps Heritage Foundation for telling stories of Marines in local communities. While adept at reporting hard news, she's known for telling human stories of conflict, struggle and joy. Erika has a comprehensive understanding of issues affecting South Orange County communities, including coastal access and the environment, the plight of marine mammal entanglements, water quality, development, local harbors and quality of life in Newport Beach, Laguna Beach, Dana Point, and San Clemente. She's reported from Navy ships, Osprey aircraft and training ranges throughout Southern California, explaining national and international warfare tactics and military equipment. She covers military and national defense from West Coast bases to the Pentagon.

Schulman-Janiger said the whale, a male, has been documented in the area since 2019. The last single sperm whale recorded in the area was off Malibu on Sept. Sperm whales can be identified from a distance by notches in their flukes. She also keeps an eye out for returning whales. Since then, she said she’s not seen another one leaping from the water. That day was also the first time she ever saw a sperm whale. She was looking for early gray whales when the whale “rocketed up” into her view field. Schulman-Janiger said she witnessed her first breach of a sperm whale off Point Fermin in 1983. Occasionally single or paired males have been seen. “We do not see bachelor pods of male sperm whales here,” she added about the special event it was to see so many together. ![]() “To catch a breaching sperm whale is stunning,” she said after seeing photos taken by Trowbridge. Seeing a pod of several sperm whales is very unusual in Southern California and seeing one breach is even a greater rarity, said Alisa Schulman-Janiger, a marine biologist who founded the American Cetacean Society Los Angeles Chapter’s Gray Whale Census and Behavior Project run at the Point Vicente Interpretive Center. ![]() With whaling less of a threat now, their population has improved.
