Thats interesting about Sea lice Faith. I'd never heard of them.
Here's a photo :
Look abit like tadpods.
Here's a fact sheet about them:
http://www.aquacultureassociation.ca/news/Sea_Lice_Fact_Sheet.pdf
They are parasitic copepods that are commonly found on fish in the marine environment.
"Sea lice are naturally occurring parasites that have existed for millions of years and have been reported on wild ocean fish like salmon, stickleback and herring for centuries."
Life stages:
"The salmon louse has 10 life stages, each characterized by a molt, or transformation, that takes it from egg to adult. Once the young louse reaches the free-swimming stage called copepod, it is able to attach onto a host, where it grows to the adult stage and is able to produce eggs that are subsequently released into the water column, thereby completing the life cycle."
They dont affect human health...according to that pdf.
Scroll down in this production and you'll come to a diver's back that been attacked by sealice:
"This is a dermatitis that is thought to be caused by the larva of the thimble jellyfish. The nematocysts of these larvae accumulate in areas of bathing suit contact and cause a severe dermatitis that can be painful and/or pruritic. It usually resolves in about 1 week, but can recur if the dive suit is not rinsed carefully. Steroid creams are said to be helpful.
Burrowing anemone:
..... "also caused in Florida by larvae of a burrowing anemone (same mechanism, nematocyst stings) which is apparently more common following beach "renourishment" projects. The anemone must be an opportunist that colonizes the disturbed habitat."
So burrowing anemone can infect human skin too.
