true
A rock with lots of tiny holes can float because these holes decrease its density, making it less heavy than the same amount of water it displaces. This reduced density allows the rock to overcome gravity and float on the surface of water.
the tiny little holes that appear on a leaf which is usually a fern or mosses are calles spores. spores are very tiny singe cells.
Tiny holes in the testa, called micropyles, act as passages for water to enter the seed for germination. They also allow for the exchange of gases during respiration in the seed.
The row of tiny holes with nerve endings that feel changes in water pressure is called the lateral line. It helps fish and aquatic animals detect movement and vibrations in the water, aiding in navigation, predator avoidance, and prey detection.
pumice
Its porous, full of tiny holes and it floats.

I'd say pumice is the closest to your description.

Craters
Oil bearing rocks have millions of tiny holes where natural gas and oil are found.
a rock that is full of tiny, connected air spaces is PERMEABLE
A rock that can soak up water is called a porous rock. These rocks have tiny holes or spaces that allow water to be absorbed and held within them.
sedimentary rock
tiny holes in the skin are called pores
