=Metroid fluids=

In Metroid: Samus Returns, the Metroid species is shown to secrete a number of unidentified fluids, ranging from yellow to green in color.

Description
In the Chozo Memories, the first Larva Metroid created by the Chozo is dripping in a green liquid.

Metroid webs are initially secreted in the form of a green or yellow gelatinous fluid that seemingly hardens with time, shaping into webs before finally becoming durable, non-uniform, bio-organic structures that serve as homes for the species.

The viscous liquid is first seen near the surface of the planet in small puddles, near deceased members of the Galactic Federation Special Squadron who were killed by a Larva Metroid; their corpses and equipment are also coated in Metroid webs.

When Samus witnesses the Surface's Larva Metroid molt into an Alpha Metroid, yellow liquid begins to leak out from underneath the husk the creature discards onto the floor. The bodies shed by later stages in the species' life cycle also leak the fluid from underneath, though some of it is noticeably slightly green in color. Unlike the Larva husk, both the substance and husk eventually disintegrate/evaporate.

During the cutscene in which Samus encounters her first Zeta Metroid in Area 4, the creature is seen drooling yellow saliva. This serves as a possible indication that the species secrete their webs through their oral cavity.

Several rooms within the hive feature a green-colored liquid in the background of the hive, most notably in the Queen Metroid's chamber where several hatched Metroid Eggs are found. A similarly green liquid is excreted from the Queen Metroid seen in Room MW, released whenever a Larva Metroid detaches itself from pits in her armor. The presence of this green fluid in her nest and nursing pits suggests that the Queen Metroid provides nutrients to her offspring. Curiously, each time the Queen Metroid rams against a wall, the impact causes green fluid to squirt out of the two tube-like structures on her rear; Metroid: Other M Premiere Edition refers to the tubes as her "tail" and describes the appendages as "large cannon-like holes" that fire "poisonous projectiles", likely referring to the fluid.

Curiously, when a Metroid Egg hatches in Samus Returns, the liquid released is blue rather than the expected yellow or green.

Based on the above list, it is clear that many actions performed by Metroids, such as feeding, molting, salivating and nest building, have the effect of producing the fluids that are yellow or green. Alongside this substance is also the formation of Metroid webs, with the latter possibly being merely the former in another state.

Possible link to yellow liquid
In Metroid II: Return of Samus, Samus Aran encounters pools of an unidentified highly-viscous liquid in Phase 1 and Phase 9. In the remake, this fluid is depicted as a yellow liquid.

Evidence in the remake points to the yellow liquid being a byproduct of the Metroid species' lifestyle on SR388, as the substance is always in close proximity to them. In addition to appearing in abundance in the lower tunnels and caves of Area 8 beneath home to the Queen Metroid's hive, the yellow liquid is also found in an Omega Metroid's nest in Area 6, pouring from a bio-organic structure commonly seen in other Metroid-infested rooms. The yellow liquid is also similar in color to the previously-mentioned saliva of Zeta Metroids.
