The blue whale is the largest animal known ever to have existed. [42] [43] [44] Some studies have estimated that certain shastasaurid ichthyosaurs and the ancient whale Perucetus could have rivalled the blue whale in size, with Perucetus also being heavier than the blue whale with a mean weight of 180 t (180 long tons; 200 short tons).
Rorquals are the largest group of baleen whales, with eleven species in three genera. They include the largest animal that has ever lived, the blue whale . They take their name from a Norwegian word meaning "furrow whale"; all members of the family have a series of longitudinal folds of skin running from below the mouth back to the navel ...
Rorquals (/ ˈ r ɔːr k w əl z /) are the largest group of baleen whales, comprising the family Balaenopteridae, which contains nine extant species in two genera.They include the largest known animal that has ever lived, the blue whale, which can reach 180 tonnes (200 short tons), and the fin whale, which reaches 120 tonnes (130 short tons); even the smallest of the group, the northern minke ...
The blue whale (Balaenoptera musculus) is the largest cetacean on the planet. While some have claimed that there were dinosaurs that topped its size, there is no scientific data to support that ...
The largest known species of fluke is Fasciolopsis buski, which most often attacks humans and livestock. One of these flukes can be up to 7.5 cm (3.0 in) long and 2 cm (0.79 in) thick. [236] Tapeworms The largest known species of tapeworm is the whale tapeworm, Polygonoporus giganticus, which can grow to over 30 m (98 ft). [237] [238]
Researchers described the species — named Perucetus ... The biggest blue whales found have been within that range — at around 200 tons (180 metric tons). ... Blue whales can be longer — with ...
The fluke of this species measures 2–6 m (6 ft 7 in – 19 ft 8 in) long and the 230 to 360 baleen plates are thought to grow to 4 m (13 ft) long, which is longer than that of any other whale by more than a meter. This species is sexually dimorphic as females usually reach lengths of 16–18 m (52–59 ft), while males average 14–16 m (46 ...
The whale is currently in cold storage as experts decide the next best steps. In the meantime, genetic samples have been sent to the New Zealand Cetacean Tissue Archive at the University of Auckland.
