Habitat & Fossil Locality

Waters of the Southern Ocean, from the surface down to several hundred meters (average 150 m)

💡 Everyday Comparisons for Size, Mass & Speed

💡 Its body length of 6.5 cm is similar to 2.5 Korean 500-won coins (diameter 26.5 mm) placed side by side (Comparison).
💡 A maximum swarm density of 30,000 individuals per 1 m³ works out to about 30 individuals in the volume of a 1 L water bottle (calculated at 1 m³ = 1,000 L, Comparison).
💡 Its average weight of 2 g per individual is about two-fifths the weight of a sheet of A4 paper (about 5 g for 80 g/m² paper) (Comparison).

📖 1. Overview

Antarctic krill is a small, shrimp-like crustacean living in swarms in the Southern Ocean and forms the center of the Antarctic marine food web.

🦴 2. Anatomy & Morphology

Its body is pinkish, somewhat transparent, and covered with a hard shell. It has light-producing organs (photophores) that glow blue.

🔍 3. Ecology & Behavior

It forms a feeding basket with its thoracic legs to filter phytoplankton from the water, and in winter it feeds heavily on algae growing beneath sea ice. It can survive up to 200 days without food, and swarm density can reach 30,000 individuals per 1 m³.
