Aquatic Creatures
by Arenero_
Aquatic Creatures adds sea animals, underwater armor, weapons and a set of deep ocean zones to the 1.21.4 world on NeoForge.
What it does
The mod fills the oceans with new animals. Several are dropped as items such as giant squid parts, photophores and sawfish teeth, and those drops feed the new weapons and tools. Two sea monsters are added as secret encounters, and the list of animals is reported as 30 species already included.
Four new biomes are added, among them sea volcanoes, and the ocean is divided into layers named mesopelagic, bathypelagic, abyssopelagic and hadal. Deeper layers bring more pressure, so the mod includes a titanium armor set that helps with breathing underwater and resists jellyfish and leech effects. Players advance into deeper zones by collecting diamonds for heart containers.
Aquatic Creatures runs on NeoForge for 1.21.4 only. It is client and server, so the server and every player need it. The mod is released under All rights reserved and is not open source. Its latest file is 0.8.5, published on 2025-08-29 on the beta channel.
