Fish Parasites

Mackerel Lice? - The Fishing Website Forums

This fishing site has a conversation and they say they're common in mackerel.
My only experience with fish lice was when I was raising tilapia in tanks in the Philippines. They suck the blood of the fish and make them weak .
We dipped the fish in a formaldehyde solution every three days for three treatments.
I've never seen them in the ceros we shoot here though.

I've seen these on bottom fish in Cuba.

I have seen those in snapper in their mouth.

I was cleaning sand dabs here in California and they just about all had them.

It occurred to me that this fish tongue parasite is proof that life is meaningless. There's no point spending your life stuck in some creatures mouth, unable to leave. It's just survival for survival's sake.

....and there's probably beings out there that can traverse the universe saying the same thing about us Earthlings....:)

I'll grant that there are probably other life forms in the universe, some of them intelligent. But significant space travel is likely to be physically impossible.

If we can dream it.....
And just because mankind hasn't figured it out.....doesn't mean it can't be done. God help us if we're the smartest creatures in the vastness of the universe.

Woe to the poor chimp or dog they first try it with First dog in space died within hours.

Yeah, the 0 gravity situation will be one of our undoings. Look at the space station guys after a few months. Total atrophy. But we keep learning. I think we're basically still pretty primitive animals.
