The text states that a whale's heart beats only nine times per minute.
The claim that a whale's heart only beats nine times a minute is supported by evidence indicating that blue whales have a variable heart rate depending on activity. When diving, their heart rate can indeed be as low as 2-10 times per minute. However, at the surface, it increases significantly. Reliable sources confirm this range, supporting the claim within a specific context, particularly when diving. Therefore, the claim is accurate within these conditions.

The whale's heart only beats nine times a minute.
The evidence indicates that a blue whale's heart rate can vary; it beats 2-10 times per minute when diving, which supports the claim about a heart rate of nine beats within that context. Higher heart rates occur at the surface, which contextually narrows the claim's accuracy to when the whale is diving.
