Like so many other sons born to whales in K- and L-Pods, Lazuli doesn't have any living siblings. A new calf seen in early 2026 might change that, as Lazuli's mom L103 Lapis is thought to be the mostly likely mother of L129, too. We will have to wait for L-Pod to return again in 2026 to learn if Lazuli does indeed now have a little brother or sister.
