Yes, krill are alive.
Understanding Krill Life
Krill, scientifically known as Euphausia superba, are small, shrimp-like creatures that belong to the plankton family. They are not just drifting passively in the water; they are active swimmers, which can sometimes make them seem more like little fish than typical plankton.
Key Characteristics of Krill
Here's a breakdown of key characteristics that highlight that krill are living organisms:
- Size and Appearance: Krill grow up to 6cm in length and resemble small shrimp.
- Lifespan: They live for up to five years, indicating a definite life cycle.
- Activity: They swim actively, moving independently in the water.
- Part of the Plankton: Krill are some of the largest members of the plankton family.
Why This Matters
Understanding that krill are living creatures is essential because they play a critical role in the marine ecosystem. They are a primary food source for many animals, including whales, seals, penguins, and many other marine species. Their health and population levels can significantly impact the broader marine food web.
