The southern right whale (Eubalaena australis) is a baleen whale, one of three species classified as right whales belonging to the genus Eubalaena. Southern right whales inhabit oceans south of the Equator, between the latitudes of 20° and 60° south. [5] In 2009 the global population was estimated to be approximately 13,600. [6]
Southern right whale in the breeding grounds at Peninsula Valdés, Patagonia. In 2000, two studies of DNA samples from each of the whale populations concluded the northern and southern populations of right whale should be considered separate species. What some scientists found more surprising was the discovery that the North Pacific and North ...
Though zooplankton abundance began to rise again in 1999, right whales have such a long reproduction and migratory cycle that the population was greatly affected by the minimal food availability from the year before. In 1999, only one right whale calf was born, compared to the 21 that were born in 1996, before the climate shift.
An unusual journey. In her 26 years working with right whale sighting networks, Albert has seen right whales travel into the Gulf fewer than a half-dozen times.
With a population estimated at between 300-350 individuals, [19] the North Atlantic right whale is the most critically endangered great whale. The Northern Pacific right whale is also endangered with only about 500 individuals extant. [16] [17] The Southern right whale (~7500 individuals in 1997) and the Bowhead whale (20,000 to 40,000) have ...
The skim-feeders are right whales, gray whales, pygmy right whales, and sei whales (which also lunge feed). To feed, skim-feeders swim with an open mouth, filling it with water and prey. Prey must occur in sufficient numbers to trigger the whale's interest, be within a certain size range so that the baleen plates can filter it, and be slow ...
A North Atlantic right whale has been spotted entangled in rope off New England, worsening an already devastating year for the vanishing animals, federal authorities said. The right whales number ...
An unknown species of right whale, the so-called "Swedenborg whale", which was proposed by Emanuel Swedenborg in the 18th century, was once thought to be a North Atlantic right whale. Based on later DNA analysis, those fossil bones claimed to be from Swedenborg whales were confirmed to be from bowhead whales.
