Tampines North Primary School, SIngapore
Anything that is denser than water (heavier for how much space it takes
up) will sink. Sharks sink because they have a lot more muscle and
cartilage than other types of fish - muscle and cartilage are very
dense. Many other types of fish have more fat, which is very light and
helps to make them float higher up. Other types of fish that will sink
include all of the 'bottom dwellers,' like catfish.
