Each empty Ballphin Palace respawns a Bottlenose Ballphin every 4 days. However, a Ballphin Palace can hold an infinite amount of Ballphins; The Palace Ballphins return to at dusk is determined by the creator of the ballphin herd (the first Ballphin in the herd). Since Ballphins will group together in herds of 12 and start living in the same Palace this usually results in most of the Ballphin Palaces being empty so they start respawning. Ballphins that live in Palaces cannot reproduce normally via mating in mild as the herd is deleted when all its members enter the Palace so there only means of reproduction is through an empty Palace respawning them.
As with most craftable structures, Ballphin Palaces (including naturally occurring ones) can be Hammered to return half of the resources needed to craft it.
Tips
Unlike with Pig Houses, the lights of a Ballphin Palace will not go off when the player gets too close. This allows them to be used as a rather cheap nighttime light source, if the player's boat has enough durability to last a night at sea.
Bottlenose Ballphins do not react to the player destroying their palace, so these can be a decent source of Limestone if the player cannot find any Coral Reefs.
Trivia
Ballphin Palaces were added to the Shipwrecked DLC more than a year after its official completion in the Home Sea Home update, after being tested in a beta branch for several months.
