For most species, reproduction is seasonal. Ovulation coincides with male fertility. This cycle is usually coupled with seasonal movements that can be observed in many species. Most toothed whales have no fixed bonds. In many species, females choose several partners during a season. Baleen whales are largely monogamous within each reproductive ...
Humpback whales may also make stand-alone sounds that do not form part of a song, particularly during courtship rituals. [15] Finally, humpbacks make a third class of sound called the feeding call. [citation needed] This is a long sound (5 to 10 s duration) of near constant frequency. Humpbacks generally feed cooperatively by gathering in ...
Whales are fully aquatic, open-ocean animals: they can feed, mate, give birth, suckle and raise their young at sea. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 tonnes (210 short tons) blue whale, which is the
Scientists think they might have finally learned the secret to how whales sing their complicated songs. We knew whales made a vast array of vocalizations, called songs, that can carry for ...
Beluga whales and narwhals use high frequency vocalizations for echolocation; while beluga whales typically utilize higher frequency vocalizations than do narwhals, their vocalization ranges are overlapping. [10] Both species show evidence of context-dependent vocalizations. [11] [12] This indicates possible social compatibility between the two ...
A San Diego-based ecotour operator has captured stunning aerial footage, perhaps first of its kind, showing Cuvier’s beaked whales swimming along the surface. Rare footage shows elusive ...
Nevertheless, they do in fact make a significant difference because saving a few whales in a population of only 400 has a large positive effect against mortality rates. Between 2004–2008 there were at least four documented cases of entanglements for which the intervention of disentanglement teams averted a likely death of a right whale. [ 35 ]
