Until recently, technology limitations have made it challenging to effectively study the aggregation behavior of beluga whales. As climate change continues and sea surface temperatures rise quickly, the ability to do so becomes ...
A team of oceanologists affiliated from the U.S. and Scotland has found reductions in body size of female North Atlantic right whales is resulting in fewer births, endangering the species. In their study, published in Royal ...
While the sounds of our oceans may be familiar to us through the lens of nature documentaries, from the haunting calls of whales to the barks of some fish, this acoustic environment can provide a wealth of knowledge to scientists ...
In the ocean, both natural and human-driven factors may cause ecosystems to undergo transformations. Such changes, whether sudden or gradual, can affect the food web by causing redistribution of prey upon which seasonal predators, ...
Researchers at Nanjing Normal University, China, have investigated the genetic underpinnings of mammalian longevity in search of new strategies to extend human lifespan.
Loss of habitat and human activities such as fishing and shipping pose a grave threat to wildlife but diseases driven by the smallest organisms in the ocean are a less understood side of marine conservation.

Researchers in Japan led by the RIKEN Center for Biosystems Dynamics Research, Kobe and Osaka Metropolitan University, Osaka, have discovered that whale shark vision has uniquely temperature-dependent adaptations unseen in ...
Dolphins and other toothed whales are large brained top predators that captivate our imagination; they are extremely social, they cooperate, and can hunt prey down to 2 km deep in complete darkness with echolocation.

Whales are marine mammals of order Cetacea which are neither dolphins—members, in other words, of the families Delphinidae or Platanistoidae—nor porpoises. They include the blue whale, the largest living animal. Orcas, colloquially referred to as "killer whales", and pilot whales have whale in their name but for the purpose of biological classification they are actually dolphins. For centuries whales have been hunted for meat and as a source of valuable raw materials. By the middle of the 20th century, large-scale industrial whaling had left many species seriously endangered.
