Really? (seriously, not sarcastically.) I thought macrophytic algae were considered plants or protista. In order to be a zooid, the organism has to be an animal. Please explain. These classifications have changed so much since I last studied them.


I think phosphorus decree answered your question. Macrophytic algae have motile gametes - to an alien they might even be mistaken as sessile photosynthetic animals.

Unicellular algae like dinoflagelletes are capable of becoming predators hunting and using phagocytosis to eat other unicellular animals and plants.

Hunter-killer dinoflagelates! How bizarre. I kind of associate those things with coral reefs, where they live inside the polyps and supply them with energy.

I pulled out a few.

- The most homicidal mammal on earth was found to be the meerkat, with roughly one in five dying at the hands of others.

- Crocodilians are more closely related to birds than they are to snakes, lizards, or turtles.

- Cougars, cheetahs, and snow leopards all can’t roar.

- Hairy frogs intentionally break their toe bones through their skin to function as claws for self-defense.

- Sea cucumbers expel their internal organs out their anus when attacked, which does not harm them.

- Chameleons do not change to color to match their surroundings, but rather to regulate their body temperature and communicate with others.

You are referring to zooxanthelle algae which supply sugars to coral polyps.

Not so much racist as speciest; they recognize the superiority of cats.

And ligers are awesome.

On that note anyone heard of grizzy-polar bear hybrids
https://www.bbc.com/news/science-environment-36381785
Since Grizzly bears have a adapted to a wider distribution these hybrid bears could travel all the way down to Canada.
Imagine living in the Canadian suburbs and having Polar bear sized predators rummaging through your garbage bins :lol:

that cannot be refuted at all --yet most people love cats. the cat family in general.

imagine something you found adorable and beautiful all your life..maybe even saved as a desktop wallpaper on your computer...
being the reason you die (eg being attacked by a tiger)...
entire villages have been terrorized by 1 or 2 tigers ... my grandmother told me some stories as she grew up in a village in India herself.

Apparently these grolars surprised native americans and Sherpas in the Himalayas who weren't used to seeing ginormous hairy creatures so called them Sasquatch and Yetis. or so the story goes.

why are frogs and toads so strange...
there are the horned toads which i believe shoot out blood from their eyes to scare off predators.

In a similar vein (lol), the hairy frog breaks its own toes in order to stab would-be attackers with the sharp end.

I have found out one useful thing about pholcid spiders. (That's the extra-spindly ones, AKA "daddy longlegs" or "cellar spiders.") If you scoop one up on a feather duster, it will climb slowly around on the wool in confused manner. By carefully turning the duster to keep the spider on top, you can carry it through the building to the outside. Then just turn the duster over and let the spider climb off unharmed.

Which gives me an excellent idea for a variant on the egg-and-spoon race....
