Coral reefs are in great threat of going extinct. When this happens, its inhabitants will go instinct as well. Krills are considered one of the most endangered species in the world. One of its inhabitants that are on the verge of going extinct is the krill. Krill has become an endangered species because corals are on the verge of becoming extinct. When the krill is gone, whales will be affected as well because the krill serves as their food.

Krill is Norwegian for whale food. These are eucarid crustaceans that can be categorized into two families. They can be categorized as Bentheuphausiidae and Euphausia superb. The prior is composed solely of Bentheuphausia amlyops while the latter includes the rest of the 88 species of krill. The later is also popularly associated with krill.

The Euphausiidae families are like shrimps and are crustaceans. They are usually found in dense shoals in the Antarctic waters. Swarms of krill are as many as 10,000 per cubic meter of water and can occupy kilometers of water space. This means they can get pretty many in one place. They have lengths from 8 mm to 14 cm. They light up with a strong blue-green light. They glow to communicate, congregate and procreate.

They have hard-calcified exoskeletons like most crustaceans do. It is divided into three segments. These segments are called tagmata. These segments are cephalon, thorax and abdomen. The head is connected to the thorax and is called cephalothorax. This area of the krill is sometimes hard to tell from each other. Its body has complex structures for each segment.

The Bentheuphausia family of the krill is a species called bathypelagic and can be seen in the southern part of the North Atlantic Ocean. The Euphausia, on the other hand, are found in the Atlantic waters. The prior are found 1000 m deep while the later can be seen 100 m deep of the water.

There are 85 species of krill all over the world. This is according to a website created by Ocean Explorers. There are many other marine animals that depend on the krill. This is why the krill is a very important part of the marine food chain. It is very important to the marine ecosystem. If the krill will be gone, much of the marine ecosystem will be greatly affected. This is why it is very important to preserve the krill. Preserving the corals can simply do preserving them.

Krill are called zooplankton. This means they are marine animals that usually stay near the surface of the ocean. The Antarctic krill is one of the largest of its type. It can reach the length of up to 2.5 inches. There are around 6 billion tons of these creatures in the Antarctic. They live in both cold and tropical waters. They can also be found in the Arctic and Antarctic oceans. During the day, they stay low to get away from predators, but at night they are the predators who stay near the surface to eat microscopic phytoplankton.

So, to save the marine ecosystem, saving the krill is a very important thing to do.
