they are neutrally buoyant. they have ballast tanks to achieve this
The problem statement would typically involve how to make a paperclip float or suspend in a liquid, such as water, without sinking or fully submerging. The challenge may be to find a way to alter the paperclip's buoyancy or surface tension of the liquid to achieve this desired effect.
Basalisk
you cant see them under the water and so they can attack without being seen.
Submerging.
there are micro hairs that are almost water proof
Insects are able to walk across bodies of water without sinking because of their weight. Insects weigh literally nothing.
Add oxygen to the water
submerging itself in water.
By reducing their bouyancy, through letting seawater into the ballast tanks then sinking to the desired level . When they want to stabilize or rise they use compressed air to blow this ballast water out.
fast enough to run on water without sinking.
with aggression or submerging in water, its natural environment
Water displacement is a method used to measure the volume of an irregularly shaped object by submerging it in a container of water and measuring the amount of water that is displaced. This helps in determining the volume of the object without the need for complex measurements.
