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.
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.
This is a miniature version of the humpback whales' strategy, which involves fasting during their months-long migration from arctic feeding areas to tropical breeding/nursing areas and back. Phocids produce thick, fat-rich milk that allows them to provide their pups with large amounts of energy in a short period.
Ky is a very large male and can still do many athletic behaviors such as front flips. He is the largest orca at San Antonio, weighing over 9,000 pounds and over 22 ft long. He is a reliable whale and is most often grouped with Tuar, though he likes spending time with Takara and can be seen with any of his pod mates.
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.
The nine outcome targets include: Conserve and restore terrestrial and freshwater ecosystems; end deforestation and restore degraded forests; end desertification and restore degraded land; ensure conservation of mountain ecosystems, protect biodiversity and natural habitats; protect access to genetic resources and fair sharing of the benefits ...
Plants mount local and systemic defenses against aphid attack. Young leaves in some plants contain chemicals that discourage attack while the older leaves have lost this resistance, while in other plant species, resistance is acquired by older tissues and the young shoots are vulnerable.
