  1. When a whale dies and sinks to the ocean floor, it becomes a feast for many sea creatures. This event leads to a chaotic but vital ecosystem around the whale carcass.
  2. After larger scavengers eat their fill, bacteria step in to break down the whale's body, turning it into nutrients for other life forms. This process creates a thriving community in a place that usually has little life.
  3. The cycle of life and death in the ocean shows that nothing goes to waste. Even in death, a whale can support new life for decades, reminding us that everything in nature is interconnected.

  1. A small bird was saved from a drainage pipe, showcasing the joy of saving wildlife. It’s a reminder that nature can surprise us and that we can make a difference.
  2. Opalescent squid lay their eggs in clusters that wash ashore, but most will die out of water. This highlights the fragility of marine life and how conditions affect their survival.
  3. Pelagic gooseneck barnacles live on floats in the ocean but end up on shore after they die. Their life cycle shows the interesting connections between different marine creatures and their environments.

  1. Harbor seals and sea lions can adapt to both saltwater and freshwater environments. They often move between these waters, showing their ability to thrive in different conditions.
  2. These animals have a unique way of navigating locks to switch from saltwater to freshwater. They can either wait for the locks to fill or use special culverts that help them travel.
  3. The history of these seals goes back to the Ice Age when they may have lived in freshwater lakes. This history could explain why they are drawn to freshwater today.

  1. Baitballs are when schools of fish, like herring and sand lance, gather together as a defense against predators. This helps reduce the chance of any single fish being eaten.
  2. When birds like gulls dive into the water, it often signals the presence of baitballs. Their activity gives hints about the underwater life that we usually can't see.
  3. Baitballs are important for the ecosystem because they provide food for many animals, including seals and birds. Observing these events can give insights into the health of marine life.

  1. Herring spawning events are vital to Puget Sound's ecosystem and attract a variety of wildlife. These events help connect the food chain and support many animals, both sea life and birds.
  2. Each female herring can lay a huge number of eggs, which provide food for young fish and other creatures. This means herring play a crucial role in nourishing the local food web.
  3. Herring are not only important for marine life but also for Indigenous communities. They have been a key food source for these communities historically and continue to be significant today.

  1. Teredo clams, often called shipworms, are actually bivalve clams that eat wood. They can cause significant damage to wooden structures, like piers, making them a big problem for dock builders.
  2. These clams have been around for thousands of years, munching through wood in many parts of the world. Their destructive nature has been noted by writers and maritime workers throughout history.
  3. Modern efforts to control shipworm damage include using less wood in construction. Despite past challenges, these clams are still here and likely will be part of our marine ecosystem for a long time.

  1. An algae domestication program won a Seaweed Ideathon, focusing on sustainable agriculture practices and biostimulant production.
  2. Investors are showing interest in aquaculture technology, with significant funding rounds announced for seaweed-derived products and sustainability initiatives.
  3. Job opportunities in the seaweed and microalgae industry are on the rise, with companies like PhycoWorks and GreenWave actively recruiting for various positions.
