Spindle cells (neurons without extensive branching) have been discovered in the brains of the humpback whale, fin whale, sperm whale, orca, [15] [16] bottlenose dolphins, Risso's dolphins, and beluga whales. [17] Humans, great apes, and elephants, species all well known for their high intelligence, are the only others known to have spindle cells.
In 1970 the biologist and environmentalist Roger Payne recorded and produced the popular Songs of the Humpback Whale album, after his 1967 discovery (with Scott McVay) of whale song among Humpback whales. [16] With the growing popularity of entertaining cetaceans came information and even warnings about the threats to these adored animals.
Orca show at SeaWorld San Diego. Orcas, or killer whales, are large predatory cetaceans that were first captured live and displayed in exhibitions in the 1960s.

In India, an elephant was helping locals lift logs by following a truck and placing the logs in pre-dug holes upon instruction from the mahout (elephant trainer). At a certain hole, the elephant refused to lower the log.
The taxonomy of the Cyanea species is not fully agreed upon; some zoologists have suggested that all species within the genus should be treated as one. Two distinct taxa, however, occur together in at least the eastern North Atlantic, with the blue jellyfish (Cyanea lamarckii Péron & Lesueur, 1810) differing in color (blue, not red) and smaller size (10–20 cm [3 + 7 ⁄ 8 – 7 + 7 ⁄ 8 ...
A few species such as the New Zealand lesser short-tailed bat and the common vampire bat are agile on the ground. Both species make lateral gaits (the limbs move one after the other) when moving slowly but vampire bats move with a bounding gait (all limbs move in unison) at greater speeds, the folded up wings being used to propel them forward.
Four main Tsimshian clans form the basic phratry. The Laxsgiik (Eagle Clan) and Ganhada (Raven Clan) form one half. Gispwudwada (Killer Whale Clan) and Laxgibuu (Wolf Clan) form the other half. Prior to European contact, marriage in Tsimshian society could not take place within a half-group, for example between a Wolf and a Killer Whale.
