As degrees of freedom (df) increase, the t-distribution becomes increasingly similar in shape to the normal distribution. This means that the tails of the t-distribution get less extreme and the distribution becomes less spread out. However, the t-distribution will never be exactly the same as the normal distribution, even at infinite degrees of freedom.
