Spending much of their lives hunting in the deep for their prey, sperm whales can dive to depths of up to 3km and hold their breath for an incredible 2 hours.Immense diving prowess aside, the social structures of sperm whales are not totally unlike that of humans. Sperm whales are the only living cetacean that has a single blowhole asymmetrically situated on the left side of the crown of the head.
With their brains being 6 times the size of ours, including the neocortex; which governs higher conscious thought, future planning, and language, they also have spindle cells, which are long and highly developed brain structures that neurologists have associated with love, suffering, compassion and speech. Individuals in the Sanctuary are almost exclusively males, females and calves living further south in the Mediterranean.In our study area they are mostly sighted over the continental slope, i.e. When they dive, they stay silent for longer than whales without whalewatch boats. One way is by examining the components of tiny pieces of sloughed skin.
Their heads are extremely large, accounting for about one-third of total body length. Originally it was used in everything from cosmetics to candles, and later on in car engines and other industrial activities too. Indeed for some of them it is difficult, even with very considerate boat driving, to get close enough to get an ID photo.
The first indication was very low numbers of dolphin sightings during late spring and early summer. Striped dolphins, sperm whales, fin whales and bottlenose dolphins are the most common marine mammals Sperm whale (Physeter catodon) The spermwhale is the largest of the toothed whales.
Sperm whales form their own separate (super)family, Physeteroidea, which includes three extant species: sperm whales, pigmy sperm whales, and dwarf sperm whales (whoever named them in English was very original). Today, Jojoba oil can be used as an alternative.Sperm whales numbers were decimated by whaling. We’ve known some individual whales for over 16 years.Sperm whales make very powerful clicking sounds (in fact the loudest sound made by any animal) to find food. As a result they are seldom found close to land though Kaikoura off New Zealand’s South Island is one exception. Sperm whales find this threatening, and almost always turn away or dive. The sea floor is shown as contours in the upper plots – just as you would plot the height of a mountain on a map. These clicks are far louder than a helicopter hovering right outside your bedroom window, and the largest whale can generate 230 decibels, deeming them the loudest animals on the planet.As the whales emit these clicks and whistles, they then listen to these echo’s and are able to create a three-dimensional picture of their surroundings. A firm favourite amongst sperm whales, giant squid top the menu.
Although they spend the majority of their time in deep-deep waters, we had the amazing opportunity to spend a little quality time with these whales just outside our harbor in Dana Point.In 2014, a pod of over 60 sperm whales visited Dana Point, California.
(Hefty-hefty earbuds, people. These toothed whales included 11 different species, such as dolphins, porpoises, beaked whales, and sperm whales. And they’d most likely give you a hug if their somewhat small flippers were any larger in size.Sperm whales could be seen at any time during the year here in Dana Point, but because of their love for deep sea diving in offshore waters, their visits are very rare and extremely special.Here at Captain Dave’s, we are so fascinated with these highly-developed specimens, that we breach at any opportunity to take a glimpse at their magnificent selves. Apparently they like bowriding in front of the boat and usually they travel in medium to large groups.

Later on, stable isotope analysis can be carried out at the laboratory.Understanding where sperm whales look for food – and what makes these areas good hunting habitat – will help us better understand their habitat requirements. Cruising speed: Normal cruising speed is 3 to 9 mph.
Cetaceans are broadly divided into two groups, depending on whether they have teeth (odontocetes) or baleen (mysticetes). Maybe it’s a gigantic pair of killer goggles?As much as we’d like to find a giant spotlight on the noses of these whales, or pair of super-sized goggles roaming the oceans, they have something much cooler! It has a disproportionately large head and typically wrinkled skin.
