The New York Times has an interesting article about a giant 1.5 inch diameter amoeba (Gromia sphaerica) that can roll itself along the ocean floor. That's pretty big for a single celled organism! I wonder what the biggest 'single cell' is? I guess for length you'd have to go for a blue whale neuron ... For size? An Ostrich egg perhaps (if you can include gametes). Interesting that whale ova are smaller than ostrich ova- this is probably the whole point of a placenta.
Why are we happy to eat the ova of chickens but not rooster semen? I wonder what Gromia tastes like?
Other Food Things I Wish I Could Forget:
1. eggs are chicken ova
2. gelatine is made from boiled animal bones and skin.
3. musk comes from a gland near the anus of deer.
4. the bacteria responsible for stinky cheese is also found between the toes.
