New research shows that global climate change will affect the distribution of phytoplankton. Under warmer conditions, phytoplankton are expected to migrate away from the tropics and shift towards the cooler polar waters, which means we will have less diversity of phytoplankton around the tropics, which could also reduce fish diversity, impacting millions of people that rely on this food resource.
A female zebra shark living in captivity at a hotel in Dubai has had four recorded births, despite the fact that she has not mated with any males! Some animals, including some amphibians, reptiles, birds, and sharks, are able to have offspring by so called "virgin births" (parthenogenesis) where a female creates a fertile egg without sperm from a male.
A tsunami is a giant wave generated when an earthquake, landslide, or volcanic eruption occurs under water. The wave can carry a large amount of energy. As this massive energy approaches shore, the wave grows higher and higher and can come very far inland. Always heed tsunami warnings and head to higher ground!
Hawaiʻians are well known for their strong ocean voyaging heritage. Archeologists have discovered that Egyptians were also adept seafarers. The Egyptians built massive ships capable of traveling over 1000 miles. Furthermore, these ships were built to be disassembled and reassembled, because the Egyptians had to break them down and carry them 100 miles across the desert to trade goods.
Water is a unique molecule. Most liquids become denser as they cool down, but when water freezes, it becomes less dense, allowing ice to float. If ice did not float, a lot of animals would be in trouble. In fresh water ecosystems, animals rely on the top layer of water freezing over, which actually allows heat to be trapped underneath and keeps them alive through the winter.

In the journal, Proceedings of the Royal Society B, researchers provide evidence that species with lower energy requirements may be less likely to go extinct. In the study, the researchers analyzed the metabolic rates of 299 species of bivalves and gastropods in the Western Atlantic, both extinct and extant. They found that during a 5-million-year period, high... (more)
