Eavesdropping on whales using land seismometers

In a newly published study in Seismica, researchers used instruments on land designed to monitor earthquakes (seismometers) to detect the presence of fin and blue whale calls in the Gulf of St Lawrence.   What is a seismometer?  Seismometers are instruments that measure the ground motion and are typically used to study earthquakes. However, they can

Can Whales Eat and Swallow Humans?

Whales are unlikely to swallow humans due to their anatomy and behavior. Baleen whales, with small esophagi, filter-feed on tiny prey, while toothed whales have larger throats but do not treat humans as prey. Encounters are generally non-aggressive and driven by curiosity. Historical anecdotes and myths exaggerate these possibilities.

Whales and Dolphins Uniting for Survival, Bounty, or Companionship?

Cetaceans like whales, dolphins, and porpoises form interspecies associations for predator deterrence, predator avoidance, foraging, and socialization. These behaviors can involve thousands in a pod, with practices like coordinated feeding and shifts for vigilance against predators. Such alliances may also have aspects like alloparenting and possible interspecies communication, showcasing complex social dynamics and cooperative strategies among different species within the marine environment.

Why are baby whales and dolphins born with whiskers?

Vibrissae, or whiskers, are found in most mammals, including cetaceans like dolphins, whales, and porpoises. These were likely inherited from terrestrial ancestors, serving as sensory organs during these species’ evolution from land to water. While in many cetaceans, whiskers disappear as they mature, leaving behind small cavities termed ‘vibrissal crypts’, certain species, such as the Amazon river dolphin, retain them, helping in food detection and possibly electroreception.
