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.
Even though it’s harder for humans to hear when underwater, sound travels much faster and farther in the ocean than in the air. That allows some animals, like humpback whales, to communicate over very large distances and is why you can sometimes hear them singing loudly while underwater during the winter months.
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!
Can you imagining putting a person in a time capsule and then opening it up 80 million years later to discover that they’re still alive? Scientists have found a bacterial colony buried 100 feet deep in the Pacific Ocean floor that hasn’t received light, oxygen, or food for over 80 million years, and they’re still alive! A very slow metabolism and dividing to make identical copies of themselves allow these bacteria to survive for so long.
Ocean phytoplankton produce at least half of the oxygen that we breathe. Though small in size they are able to produce as much oxygen as all of the land plants on earth combined. While trees and plants usually get all the credit for our oxygen, we actually should be thanking our marine plankton!
Photo: SECORE Synchrony of reproduction is an important strategy used by both terrestrial and marine organisms to maximize their reproductive success. Depending on the ecological context, synchronization of reproduction may offer advantages in increasing fertilization success, reducing predation through “swarming”, and ability to locate mates. Timing of reproduction and large reproductive events in a population is dependent on the “clock” set by environmental cues, such as temperature, chemical cues, irradiance, lunar cycles, tides, wind or current patterns, and timing of...
