Deep Sea Fish Eat Greens?


While we've been studying oceanography, we also looked at some of the animals that live in the ocean. We found out that the animals at the surface eat the algae, which creates that food chain, and that the animals at the bottom of the ocean eat dead animals that float down and whichever live animals they can catch. Scientists have now found that some common deep-sea fish are eating pieces of plants that fall down to the bottom. This isn't an entirely new discovery, though. Scientists have found plant remains in the stomachs of deep-sea fish before and there is a species of crab which eats wood that falls to the ocean floor, but this is the first time that deep-sea fish eating plants has been caught on tape. The scientists sent a rig, which contained spinach, with a video camera on it into the North Atlantic sea and at around 3000m down, it released the spinach and soon after the bait was dropped, at least three species of deep-sea fish began it eat it (grenadiers and cusk eels). Scientists will now be looking at how this new discovery affects the food web.
