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!
If you could take all of the bigger organisms of the ocean (whales, sharks, fish, squid) and add up their total weight, and then took all of the microscopic organisms (like plankton) in the ocean and added up their total weight, which one would weigh more? You might be surprised to hear that the microscopic organisms weigh over 40 times more than all other organisms in the ocean combined!
Water is an incredible molecule with a variety of qualities that facilitate life on earth. Water molecules form bonds with each other called hydrogen bonds, which allows water to stick to itself. This creates surface tension, which some insects use to walk on top of the surface of the water. This is also why it hurts when you do a belly flop!
Nudibranchs are a type of sea slug whose name means “naked gill” and they have some crazy ways of living. They come in many shapes and colors and can be found both in reefs and sandy ocean floors. One kind of nudibranch can eat a toxic sponge and store the poison in its own body, giving it a new defense mechanism. Another type farms algae within its body and uses the algae to make food for itself from the sun.
Even though they live in the ocean, dolphins and whales are not fish! They are warm-blooded mammals that breathe air, and feed their calves milk, just like us. In fact, even though they have very smooth skinned bodies, they also have hair. Some shed these hairs when they are born, but others still retain small hairs on their faces.
In the Salish Sea, off the coast of Washington State, three pods of orcas (J, K, and L) make up the Southern Resident Killer Whale population. This population of orcas is designated as endangered and is tracked closely by researchers to monitor their health, survival, and movement. J, K, and L pods each have a distinct dialect of clicks, whistles, and calls that are used to hunt and communicate. The Southern Residents primarily eat Chinook Salmon, another endangered species in the Pacific Northwest. In a recent study, researchers have found that ship noises in the heavily traveled... (more)
