SeaHarmony welcomes all ocean scientists, ocean educators, resource managers, artists, and ocean related organizations and community groups.
Despite their misleading name, sea cucumbers are not vegetables of any kind. These slow moving, soft bodied relatives of starfish and sea urchins live on the sea floor eating organic particles and microscopic marine animals. Sea cucumbers are important animals on coral reefs because they help remove dead material from ocean sediments.
Why are people so worried about plastic pollution in the ocean? Plastics break into smaller plastic pieces, but never completely break down. The tiny plastic pieces get eaten by small fish and crustaceans, which then get eaten by bigger fish, albatrosses, whales, and sharks. These plastics can cause serious harm once ingested resulting in starvation, and internal injuries. Remember, plastics are forever.
What’s the longest mountain range on Earth? Nope it’s not the Andes! The Mid-Ocean Ridge is a long connected series of underwater mountains that crisscross the globe like the seams on a baseball. This long mountain range is found in all of the world’s oceans and is made up of oceanic crust or rock that is 200 million years old.
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.
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.

Although the regions are vastly different from each other, Arctic and Antarctic systems are among the most impacted by global climate change. However, the remote nature of these areas makes scientific study of organisms and the environment difficult and expensive. Recently, two studies provide further insight into the biology and ecology of organisms in these extreme... (more)
