Much like many species of the unrelated Snufflers on land, the Squigglets are an integral component to marine ecologies on the seabed - consuming detritus and substrate-dwelling microbes, in turn providing food for much larger organisms.

Descended from a population of Soopierworms that have settled into a more benthic life, Squigglets have adapted accordingly. As these organisms spend much of their time on the substrate, their lateral setae have become longer to better move through sediment - whether on or in via burrowing; although still capable of some weak swimming, Squigglets usually won’t go very far. The mouth has become a rasping radula-like configuration, somewhat downturned to rasp at whatever suitable organic matter it comes across. The ancestral eight eyes form an arc around a Squigglet’s head, giving it decent visual awareness. More keen than its sight however is its chemoreception; an elongate seta rapidly flicks about the water column in search of organic olfactory signatures, and should it get awareness of the source, convene right towards this meal. The ventral setae are absent to minimize friction.

Sometimes a Squigglet would convene towards another Squigglet of that species, in most instances to mate. They will to link up their gonads and exchange genetic material, eventually one of them will end up depositing a clutch of eggs in the substrate. Each clutch contains many hundreds of eggs which hatch into planktonic larvae, typical for an r-strategist.
