What do krill do to mate?

When They Breed
  • Krill reach sexual maturity after 3 years, and both male and female krill are required to reproduce. During the dark, cold months krill shrink in size and lose their reproductive capacity--a process called "regression." As warmth, hours of light and food supply increases, they become sexually mature again.

How They Mate
  • The male produces tiny sperm packets and uses his legs to transfer them to the female's reproductive organs. The female stores the sperm packet in a pouch until she is ready to lay her eggs. The eggs are fertilized while leaving her body.
