Darkness all around. Like an infinite black hole. Only flashes of light from fish. So much pressure, it feels like you are being squeezed into a ball. That’s what it would be like to live in the deep dark depths of the Pelagic zone, so fish make big adaptations to be able to live down there. One quick definition everyone should know is ecosystem. Ecosystem means all of the living things (plants and animals) and nonliving things that live in a specific area and interact with each other.

According to the text, “Warming ocean waters, rising sea levels, and violent storms disrupt the lives of many species and affect fragile marine ecosystems” (Dignan 14). This obviously shows that climate change is an environmental threat to the Black Dragonfish since it’s used to living in the deep, cold water and if the water warms up, it won’t be used to the temperature and it could die. Even so, the final environmental threat the Black Dragonfish faces is ocean acidification. The text clearly states, “Ocean acidification also decreases the ability of many organisms to build shells and skeletons. It disrupts food chains and affects the reproduction and health of many species” (Dignan 15). Clearly, this shows that ocean acidification is an environmental threat to the Black Dragonfish because if any of those things happen to it like it disrupts the food chain or it affects the health of many
