Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Minke whales may be as long as 10 m (33 ft). Their large range stretches from Southern California to the Bering Sea, and their social structure and prey preferences are still unknown. Adopt a whale and help us protect these amazing creatures. Resident orcas are fish-specialists, named so because they tend to have small home ranges around areas of large fish populations. Since then, there have only been a handful of sightings of this rare ecotype, but enough for researchers to realize they are a unique ecotype and not just a mutation. Type 2 orcas prey primarily on other whales and dolphins, particularly minke whales. In 2012, a push was made to rename this type of killer whale in memory of Dr. Michael Bigg.

Killer Whales vs. Minke Whale “To kill a whale is very difficult and takes a lot of energy, but they can do this by cooperating, and the whale is large so it provides food for everybody.” Just behind the dorsal fin is a patch of gray called a \"saddle\" — because it looks like a riding saddle. In attempt to out-swim transient killer whales, minkes will maintain speeds between 15-30km/h for up to one hour. These whales have a pointed head and the curved dorsal fin is two-thirds the way along the back. 20 Dec 2010 1 … Orca pods are organized through a maternal lineage. The Minke whale is the second smallest of the baleen category. The sperm whale (Physeter macrocephalus), on the other hand, may not be the biggest whale, but it has the biggest brain to have ever existed on Earth. Normally, the Blue Whale is larger in size than the Orca. In this rare event, a pod of killer whales hunt and kill a large fin whale. About 800,000 Minke whales exist in the world’s oceans. A world where every whale and dolphin is safe and free. The biggest predator of the minke whale is the transient killer whale. Minke whales usually have a dark coloured back with flanks that are lighter. These small orcas live in closely related pods and appear to be generalist eaters. These rarely-seen orcas are large, with distinctive back-sloping eye patches, and like other mammal-eating orcas, they are especially threatened by high contaminant loads. A comparison chart of whale sizes helps put it all in perspective! It was such a great day seeing Biggs and Resident Orca, a Minke Whale and a Humpback Whale.

It has been suggested that Antarctic minke whales make up 85% of the diet of killer whales in the Southern Ocean, although this may relate to the diet of only one of the three forms of killer whales found there … As top predators, these mammal-eating orcas accumulate pollutants that are transferred through the food web and end up stored in the blubber of these whales. Other populations of orcas may be completely new ecotypes – not enough information is available to determine if they are separate from the ten described. The third ecotype found in the North Pacific, little is known about the elusive Offshore orcas, as they live far from land – mainly over the outer continental shelf - and are rarely encountered. The Minke reaches lengths of up to 32 feet and is a baleen filter feeders. Minke whales are the smallest of the rorqual whales.

The orca's (Orcinus orca) size of up to 31 feet (9.4 meters) makes it the largest dolphin. 2011). Research on Type 1 orcas is ongoing, and photo-identification studies are gradually revealing the size and population structure of these orcas; they may be more divided into separate populations than previously thought. Residents are found on both sides of the North Pacific; the Northern and Southern communities almost exclusively eat salmon, while Residents in Alaska appear to be more generalist in their fish preference, eating multiple fish species including salmon, mackerel, halibut and cod. A comparison chart of whale sizes helps put it all in perspective! The orca's (Orcinus orca) size of up to 31 feet (9.4 meters) makes it the largest dolphin. These small populations of orcas, including the Southern Residents and those around New Zealand, do not appear to interact or interbreed with other communities, are at high risk of being lost forever. The total length (TL) measurements for each Transient orcas have been recorded by FEROP in the Western North Pacific, and populations on both sides of the Pacific carry high loads of contaminants.

It has a dorsal fin that looks like that of a common dolphin. With a life of about 20 years, these whales are hunted by Norwegian whalers, by Greenland’s native peoples and by Japanese whalers, who take 150 whales each year in the North Pacific. They are the smallest of the three North Pacific ecotypes, and are more closely related to Residents than to Bigg’s orcas, though all three ecotypes are genetically distinct. Their ranges often overlap, but they are also genetically distinct – they don’t appear to interbreed, and rarely interact with other ecotypes. Research by the Far East Russia Orca Project (FEROP) has shown that fish-eating orcas off the coasts of Russia and Japan prefer salmon and mackerel. Subantarctic orcas (the 5th ecotype in the Southern Hemisphere) were discovered in the 1950s in a mass stranding event in New Zealand. Among them are small, such as the pygmy spermwhale – 3.5 m (11 ft), and those huge, that stimulate our imagination like the blue whale and humpback.. . The resident group around New Zealand has about 117 identified individuals, who prey mainly on rays and sharks, but also fish and other whales and dolphins – not quite fitting in with any described ecotype in the Southern Hemisphere.

Their low numbers and our lack of knowledge have important conservation implications for the survival of these communities. Bigg’s killer whales range all along the west coast of North America, from California to Alaska. 3), and covered distances of 15 km or more. Over the last few decades, as wild orca research has expanded, researchers have described different forms or types of orcas.
