The blue whale (Balaenoptera musculus) is a marine mammal and a baleen whale.Reaching a maximum confirmed length of 29.9 m (98 ft) and weighing up to 199 t (196 long tons; 219 short tons), it is the largest animal known ever to have existed.
Orcas or killer whales have a cosmopolitan distribution and several distinct populations or types have been documented or suggested. Three to five types of orcas may be distinct enough to be considered different races , [ 1 ] subspecies , or possibly even species [ 2 ] (see species problem ).
Orca attacking a strap-toothed beaked whale. Orcas also prey on larger species such as sperm whales, grey whales, humpback whales and minke whales. [84] [40] On three separate occasions in 2019 orcas were recorded to have killed blue whales off the south coast of Western Australia, including an estimated 18–22-meter (59–72 ft) individual ...
“The blue whale is the largest and loudest animal on Earth.” The blue whale is the largest animal on Earth and likely the largest animal ever to have lived. While this ocean mammoth is dubbed ...
The La Plata dolphin has an EQ of approximately 1.67; the Ganges river dolphin of 1.55; the orca of 2.57; the bottlenose dolphin of 4.14; the tucuxi dolphin of 4.56; [10] the pygmy sperm whales of 1.78; the narwhals of 1.76; the sperm whales of 0.58; and the blue whales of 0.19; [11] In comparison to other animals, elephants have an EQ ranging ...
Mature blue whales can reach 30 m (98 ft) in length, and the record-holder blue whale was recorded at 173 tonnes (190 short tons), [23] with estimates of up to 199 tonnes (220 short tons). [ 24 ] Another poorly known sauropod that shares similar size estimates to Bruhathkayosaurus is Maraapunisaurus fragillimus , which is based on a now-missing ...
At the time, mass estimates ranged up to 180 tons, [14] which placed it in the same category as the blue whale and the equally problematic Bruhathkayosaurus. The naming of the chimeric Ultrasauros has a similarly complicated history. Ultrasaurus (with the final "u") was the original choice, and was widely used by the media after the discovery ...
The pygmy right whale shares several characteristics with the right whales, with the exception of having a dorsal fin. Also, pygmy right whales' heads are no more than one quarter the size of their bodies, whereas the right whales' heads are about one-third the size of their bodies. [11] The pygmy right whale is the only extant member of its ...
