whale : any of various very large, aquatic, marine mammals (order Cetacea) that have a torpedo-shaped body with a thick layer of blubber, paddle-shaped forelimbs but no hind limbs, a horizontally flattened tail, and nostrils that open externally at the top of the head — Webster
Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales are creatures of the open ocean; they feed, mate, give birth, suckle and raise their young at sea. So extreme is their adaptation to life underwater that they are unable to survive on land. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature that has ever lived. The sperm whale is the largest toothed predator on earth. Several species exhibit sexual dimorphism, in that the females are larger than males. Baleen whales have no teeth; instead they have plates of baleen, a fringe-like structure used to expel water while retaining the krill and plankton which they feed on. They use their throat pleats to expand the mouth to take in huge gulps of water. Balaenids have heads that can make up 40% of their body mass to take in water. Toothed whales, on the other hand, have conical teeth designed for catching fish or squid. Baleen whales have a well developed sense of “smell”, whereas toothed whales have well-developed hearing − their hearing, that is adapted for both air and water, is so well developed that some can survive even if they are blind. Some species, such as sperm whales, are well adapted for diving to great depths to catch squid and other favoured prey.– Wikipedia

In this 4:30 minute interview with Ken Balcomb in July 2017, he talks about the lack of Chinook salmon and the stress it is placing on the endangered Southern Resident Orca population.Here are some highlights from that interview:“By 1985 there were no Chinook left in Puget Sound … And now we are pretty much seeing the same thing here.”“The salmon are smaller, much less numerous, and they are virtually all hatchery fish.” “Nobody ever thought about the […]
Home on the Range

Ken Balcomb, Center for Whale Research founder and senior scientist, responding to the misconception that the Southern Resident killer whales (SRKW) are “resident” to the Salish Sea area, where they are seen most frequently by humans. Home on the RangeWhere the Southern Resident killer whales roam and forageIt is naive to think that the Southern Resident killer whales – J, K, and L pods – are only “resident” to the inland Salish Sea and that they depend […]
How long does it take for a dorsal fin to...
by Dave Ellifrit on February 28, 2018 at 11:42 pm
When a killer whale calf is born, it's dorsal fin is bent over. When we first saw J49, in August 2012, it's fin was bent. We wondered how long it would take for it to straighten. We found the answer to that question very quickly. In this three minute video, Dave Ellifrit takes us through the first few months of a killer whale calf's development, from "tiny little wrinkly, pencilly thin sorta thing" to scaly skin and then to a plump and yellowish little whale. Very interesting and lots of fun to […]

on June 3, 2019 at 2:26 pm
Short-finned pilot whales are found over a wide swath of the world's oceans, with habitats in the Indian, and Pacific, and North Atlantic oceans. Despite this wide distribution, the whales have been recognized as a single species -- but a recent study has found that two unique subspecies actually exist. […]
Climate driving new right whale movement
on May 29, 2019 at 12:48 pm
New research connects recent changes in the movement of North Atlantic right whales to decreased food availability and rising temperatures in Gulf of Maine's deep waters. Right whales have been showing up in unexpected places in recent years, putting the endangered species at increased risk. The study provides insights to this key issue complicating conservation efforts. […]

How whales defy the cancer odds: Good genes
on May 10, 2019 at 1:13 pm
Scientists have studied potential cancer suppression mechanisms in cetaceans, the mammalian group that includes whales, dolphins and porpoises. Biologists picked apart the genome of the humpback whale, as well as the genomes of nine other cetaceans, in order to determine how their cancer defenses are so effective. […]

on June 19, 2019 at 6:00 pm
A new study from UC San Francisco suggests that a protein found in the common bullfrog may one day be used to detect and neutralize a poisonous compound produced by red tides and other harmful algal blooms. The discovery comes as these waterborne toxic events are becoming increasingly common, a consequence of climate change making the world's oceans more hospitable to the microbes responsible for these formerly infrequent flare-ups.
