Trivia

 * The Tree Leech was originally called the Barnacle Sucker.
 * Official artworks released by the developers have listed Tree Leeches as potential hazards in the future updates.
 * Earlier versions of Subnautica featured an unimplemented giant crab-like fauna called the Sandworm, that launched surprise attacks on the player from a burrow that greatly resembled a large Tree Leech. It's possible at one point this was the additional stage of lifecycle hinted at in the PDA, and their reason for being listed as a hazard. However,the Sandworm has since been removed.
