What adaptations must creatures living below 700 feet of water have to survive?
I thought that this was a great question, I had fun researching it. The interesting thing about the ocean below 700 feet is that there is virtually no light that can penetrate to such depths. Without light, algae and other plants can’t produce energy. This is a problem to the rest of the organisms because plants are generally at the bottom of the food chain. Food is therefore not as readily available as it is in other ecosystems. So, to answer your question more directly, almost all of the animals at this depth are predatory, and must get food when they can. Much of the food comes from more shallow lighted depths, and simply filters down into the deeper reaches. As you might imagine, the competition for food is huge! Animals do not live in large groups, because there isn’t enough food to support them all. Again, this poses a problem for them, because they don’t see each other often enough to find mates, and if they did, it’s still too dark to see! One way that scientists think that dee
