What you need to know about sea lice bites

Fact Checked

The actual sea lice are parasite bugs that affect fish. Sea lice are the larvae of jellyfish. The larvae contain nematocysts or sting cells just like with the adult jellyfish. Some larvae are large enough to be seen by the naked eye, but others can only be seen with a microscope. The larvae are invisible in water this is why it is difficult to tell whether or not the water is infested.
