"Maternal Communication: Female Bottlenose Dolphins' Use of 'Baby Talk' with Calves"

A new study has found that female bottlenose dolphins alter their signature whistle when communicating with their calves, similar to how humans use "baby talk." Researchers at Florida's Sarasota Dolphin Research Program analyzed audio recordings of 19 female dolphins and found that mothers used a wider range of pitches around their calves, possibly to enhance the bond between mother and calf. The purpose of using "motherese" may be different in humans and dolphins, but the study could help scientists understand the evolution of language in vocal species.

Dolphins' Electrifying Superpower Unveiled

Bottlenose dolphins have been found to possess the ability to detect electric fields underwater, a skill known as electroreception. Researchers in Germany trained dolphins to swim away from a small underwater apparatus when they sensed a weak electric field, rewarding them with treats when they were correct. While not as sensitive as sharks, dolphins can use this skill to hunt prey, particularly in murky ocean environments. The dolphins in the study showed a detection threshold similar to other species like the platypus and Guiana dolphin. This ability may also enable dolphins to perceive the Earth's magnetic field through induction-based magnetoreception, aiding in large-scale orientation.

"Bottlenose Dolphins Unveil Remarkable 'Seventh Sense' Ability"

A study has found that bottlenose dolphins are more sensitive to electric fields than platypus, making them one of the few known mammals with this ability. The dolphins were tested and found to detect electric direct current (DC) fields as weak as 2.4 microvolts per centimeter. This suggests that electroreceptivity may play a more important role in dolphins' survival than previously thought. The study also revealed that dolphins are less adept at detecting alternating current (AC) fields. The researchers believe that dolphins use echolocation to detect prey at a distance and electric fields for close-range work.

Dolphins' Electrosensitivity Unveiled: A Shocking Superpower

A study conducted by bio-scientists from the University of Rostock and Nuremberg Zoo has found evidence that bottlenose dolphins can sense electric fields. The researchers tested the ability of two captive bottlenose dolphins to detect a small electric field and found that both dolphins were able to sense DC fields with 90% accuracy. This ability likely helps dolphins detect and capture prey, as well as navigate using the Earth's electric field.
