Research shows the Hauraki Gulf Marine Park is an important area for mother and calf Bryde’s whales. 8. Population estimates conducted in Auckland suggest the Bryde’s whales have a population of around 140 animals. For this reason they have Nationally Critical status in New Zealand.
Scientists estimate there are only 135 left. And there’s no wonder why. Below the Gulf’s sparkling blue surface is an ecosystem on the brink of collapse. We’ve taken so many of their fish that Bryde’s whales are now eating mostly zooplankton, which contain lots of dangerous microplastics.
The entire world population of Fin Whales is estimated to be around 100,000.
The most recent estimate of overall abundance of Antarctic minke whales is around 500,000 individuals, down from an estimated 720,000 in earlier assessments (International Whaling Commission, 2013).
Pronounced “Broo-dus,” Gulf of Mexico Bryde’s whales are the only known resident baleen whales in the Gulf of Mexico. Experts estimate less than 100 individuals are left in the population.
Bryde’s whales have been observed in the Pacific (North and South), Atlantic and Indian Oceans and are spotted mostly between latitudes 40°N and 40°S. While most baleen whales migrate long distances between polar and tropical seas, Bryde’s whales keep to a relatively restricted home range.
The name is pronounced ‘Broo-dess’. The whales are named after Johan Bryde, a Norwegian who built the first whaling stations in Durban, South Africa in the early 20th century.
Calves are about 11 to 13 feet long at birth and weigh about 2,200 pounds, or about the same weight as a cargo container. Adult female Bryde’s whales average about 44 feet long and males average 42 feet, about the length of a school bus. Scientists are unsure what the average lifespan is for a Bryde’s whale.
The Gulf of Mexico whale is the only baleen whale living in the Gulf of Mexico full time. While the Gulf of Mexico whale shares the gulf with other cetaceans (whales, dolphins and porpoises), including the bottlenose dolphin and sperm whale, it is the only baleen whale that makes the Gulf of Mexico its year-round home.
Management Overview. The fin whale is listed as endangered throughout its range under the Endangered Species Act and as depleted throughout its range under the Marine Mammal Protection Act. This means that it is in danger of extinction throughout all or much of its range.
For many years, Icelandic whalers hunted endangered fin whales as well as minke whales. Whilst the fin whale meat was exported to Japan, most of the minke whale meat was served to tourists. The good news is that no whales have been killed since the end of the 2018 season.
Share. The fin whale is the second largest animal to ever live, in the entire history of Earth. Reaching lengths of at least 85 feet (26 m) and weights of 80 tons, this species is second only to its close relative, the blue whale.
In the North Atlantic, the type 1 killer whales consume a varied diet that includes seals and small, schooling fishes such as herring and mackerel. Type 2 killer whales specialize in cetacean prey including dolphins, porpoises, and baleen whales such as minke whales.
Norway plans to kill up to 1,278 minke whales this year, according to a recent announcement made by the country’s fisheries ministry. This is the same quota as the previous two years, although whalers only killed 503 common minke whales (Balaenoptera acutorostrata) in 2020, and 429 in 2019.
Perhaps some chemical in fish or krill also makes it into whales’ bloodstreams, giving their exhalations fishy odors. … The term “stinky minke” is a nickname minke whales earned for their odor of rotten fish. Right whales reek, too.
An estimated minimum of 300,000 whales and dolphins are killed each year as a result of fisheries bycatch, while others succumb to a myriad of threats including shipping and habitat loss.
But blue whales, which spend most of their time far from shore, are difficult to study. Whaling in the 19th and 20th centuries also culled hundreds of thousands from their ranks; an estimated 10,000 to 25,000 blue whales are thought to remain.
Currently, there are about 5-10,000 blue whales in the Southern Hemisphere and about 3-4,000 in the Northern Hemisphere [3]. Current threats include collisions with vessels, entanglement in fishing gear, reduced zooplankton production due to habitat degradation, and disturbance from low-frequency noise [1].
On April 15, 2019, NOAA Fisheries issued a final rule to list the Gulf of Mexico Bryde’s whale (Balaenoptera edeni)as an endangered subspecies under the Endangered Species Act (ESA).
This distinctive Gulf population is now critically endangered. ELUSIVE AS THEY ARE RARE, Bryde’s whales living in the Gulf of Mexico may be just one more catastrophe away from extinction. In April 2019, the National Marine Fisheries Service (NMFS) declared the Gulf population endangered.
The Antarctic blue whale (Balaenoptera musculus ssp. Intermedia) is the biggest animal on the planet, weighing up to 400,000 pounds (approximately 33 elephants) and reaching up to 98 feet in length.
In 1878, the Scottish zoologist John Anderson, first curator of the Indian Museum in Calcutta, described Balaenoptera edeni, naming it after the former British High Commissioner in Burma, Sir Ashley Eden, who helped obtain the type specimen.
Though a humpback could easily fit a human inside its huge mouth—which can reach around 10 feet—it’s scientifically impossible for the whale to swallow a human once inside, according to Nicola Hodgins of the Whale and Dolphin Conservation, a U.K. nonprofit. …
Omura’s whale is the most recently identified whale species; they were first recognised from dead specimens in 2003 and first recognised alive in the wild in 2015. They had previously been mistaken for Bryde’s whales as both species look similar, are small, and live in tropical seas.
At least seven of the Texas cetacean species are migratory, including several species of rorquals (the blue, fin, sei, and minke whales), the humpback, and the North Atlantic right whales.
1. Killer Whale (Orcinus orca) We typically think of orcas living in colder climates, but about 500 orcas live in the Gulf of Mexico where they feed on tuna and even dolphins in the Gulf’s deep waters, typically far from land.
Killer whales are the only known natural predator of fin whales, but due to fin whales’ large adult size, only calves are likely to be truly vulnerable to predation.
Blue whales are still an endangered species and there are thought to be no more than 25,000 living in the world today.
In 2020 and 2021, that total rose to 383. The numbers are split between the official whalers, the government and a third category, known as “by-catch”. This year, 37 whales can be butchered and sold by fisherman under this heading.
According to the World Wildlife Fund (WWF), over 30,000 whales have been killed by the three countries since the moratorium was established. Whales have been hunted for millennia for their meat, oil, bones and baleen (keratin plates inside a whale’s mouth used to filter small shrimp from the water).
Japan and Iceland are the only two countries that currently use this provision. Japan has been engaged in scientific whaling since 1987, a year after the IWC moratorium on commercial whaling began.
Sperm whales are the fourth largest whale species, weighing in around 80,000 lbs.
That distinction goes to the blue whale (Balaenoptera musculus), the largest animal on Earth. … 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 . A comparison chart of whale sizes helps put it all in perspective!
The Main Differences Between a Blue Whale and Humpback Whale Size: The blue whale is the largest creature on earth, around 2-3 times larger than the humpback whale.

Though penguins do make up a large part of their diet during some seasons, the Leopard Seal’s diet is more heterogeneous than one might expect. They are known to eat fish, squid, krill, and juveniles of other seal species, in addition to penguins. Killer whales are the only species known to eat leopard seals.
