8.0.4 UPDATE

Diplocaulus, ('dip-low-cawl-us', meaning "Double Caul"), is a small piscivorous prehistoric creature known from the Late Carboniferous to Late Permian of Africa and America, which were added in the 8.0.2 update. Diplocaulus are aquatic, territorial, and diurnal, meaning they are active during the day and sleep at night. Both males and females are identical, both growing to about 1 block long. The only difference between adults and babies is size, with babies being 0.4 blocks long and reaching adulthood in six days. They can be given essence of chicken to grow faster, at the cost of hunger.

Like most every other prehistoric creatures in the mod, they do not spawn naturally in the world, and must be created by the player with a culture vat. As amphibians, they hatch instantly from spawn that need to be placed in water.

Diplocaulus, like almost all other mobs, has a mood that can drop or be raised through various means. Having a low mood means it may attack or avoid you, having a high mood will make it neutral. Right-click it with a Dinopedia to see its current mood.

A fossil version of the Diplocaulus can be created by right-clicking a bio-fossil on the ground, which will create a random skeleton of a prehistoric creature with a small chance of it being a Diplocaulus.


Diplocaulus are fast-moving territorial amphibians that live in water. Although they are intended to be fully aquatic, they can survive on land, albeit they cannot move. Diplocaulus usually only attack if provoked. Although a single Diplocaulus will likely die to most other animals when it defends itself, Diplocaulus defend each other, and an intruder will anger all the Diplocaulus nearby. They eat exclusively fish, which may mean the player will have to feed them fish by hand. They are predated by nearly every other aquatic animal, with the exception of the passive fish, and Henodus.

Diplocaulus will interact with the bubble blower, and will chase toy balls, bringing up their mood significantly. They cannot however interact with scratching posts or tethered logs.

Adult Diplocaulus can breed and lay eggs every five minutes if there are a male and female present. The breeding probability is handled by how many individuals are nearby.


Diplocaulus will automatically be tamed when hatched from spawn, as long as you are within 6 blocks of it hatching. If you fail to do this, they can be tamed from feeding (which raises their mood), or with a whip, although this will lower their mood. Tamed Diplocaulus can be ordered with a Nautilus shell.


Diplocaulus is a piscivore, meaning it will only eat fish, and fish are the only thing the player can hand-feed to a Diplocaulus. When eating from a feeder, they will not be able to distinguish meat from fish, and will eat it.
