Is it possible to throw a spear underwater?

Yes, it is possible to throw a spear underwater, but its effectiveness and distance will be significantly reduced compared to throwing it in air. Water is much denser than air, creating greater resistance and drag, which hampers the spear's speed and trajectory. Additionally, the angle of release and technique used must be adjusted to accommodate the underwater environment. Specialized spear-throwing techniques, like those used in spearfishing, can improve accuracy and effectiveness.
