STATUS: LEAST CONCERN

The anatomy of a Krill is basically a standard decapod anatomy; the Krill’s body consist of three parts: the cephalothorax,  composed of the head and the thorax that are fused, and have many pairs of thoracic legs named pereiopods or thoracopods, the thoracis legs consist of feeding legs and groomimg legs, the pleon, which has the ten swimming legs, and the tail fan. The Krill’s outer shell is transparent, the external gills are visible. The Krill's eyes are compound, big and round that can adapt to different light conditions, the Krill has 2 antennae, it does not have a rostrum, and dorsal abdomnial spines. Adult Krills length are 1 to 2 centimeters long. Because the Galapagos is a tropical water the life spam of the Krill is 6 to 8 months. Krill feed on microscopic animals like phytoplankton and zooplankton and small algae. Some Krill can be carnivorous exclusively, but by nature they are herbivorous or omnivorous. The Krill filter their food from the water with the front most appendages, the thoracopods. Galapagos penguins prey Krill that has a very important role in the food chain because they convert the very small algae, so the bigger organisms like the penguin consume algae when eat Krill.
