In Java snapshots leading up to the release of 1.21.2, Turtle swimming animations were randomly changed so that their front fins will also rotate along the x axis. Whether this is a bug on Java or not, this causes the animations to no longer match between versions like they did before Java 1.21.2.

Step to Reproduce:
1. Spawn a Turtle in the water on Java Edition
2. Spawn a Turtle in the water on Bedrock Edition
3. Look at the Turtle's front fins while it is swimming in both versions, they will rotate along the x axis on Java, but not on Bedrock

Expected Result:
The swimming animations for Turtles match in both versions

Observed Result:
The swimming animations for Turtles was changed on Java, making them not match anymore
