Mammals
It seems there are more types of humpback dolphins than previously thought. A team of researchers working for the Wildlife Conservation Society (WSC) has discovered a new species of humpback dolphins swimming in northern Australian waters.
Over a hundred bottlenose dolphins have been dying off the East Coast recently. Reports said the researchers have yet to discover the cause of the intelligent animals' mass death.
Humans aren't the only ones who have names, it turns out that dolphins have names too - the only difference is theirs are composed of whistles.
Mammals such as whales and seals can hold their breaths for incredibly long periods of time, and it's not due to large lungs. Instead, scientists found that an oxygen-binding protein is responsible for the impressive dive times these creatures post.
A team of scientists have completed the first in-depth look at the evolutionary tree for placental mammals, and the results show that genetic diversity took off after the dinosaurs died out 65 million years ago.
