Leptocheliidae
Lang, 1973
Genus Guides
1Leptocheliidae is a of small, low-mobility crustaceans in the order Tanaidacea, comprising over 30 and 140 described . Members are abundant in shallow marine waters and show high sensitivity to environmental shifts, particularly dissolved oxygen and temperature changes. Global diversity patterns reveal a bimodal latitudinal distribution with peaks in lower latitudes and decline at the equator, with biodiversity hotspots in the Indo-Australian region, Central Indo-Pacific, Gulf of Mexico, and Caribbean. The family serves as an important indicator group for monitoring environmental change in threatened coastal .

Habitat
Shallow marine waters, including seagrass beds, macro-algal , and coral reefs. have been documented from tropical seaweed beds, Australian seagrass and macro-algal habitats, and Sydney Harbour.
Distribution
Global distribution with distinct biogeographic patterns. Biodiversity hotspots identified in the Indo-Australian region, Central Indo-Pacific, Gulf of Mexico, and Caribbean. High estimated richness in the Mediterranean and southeastern Australia. Subpolar and subantarctic regions support distinct but low-diversity . Bimodal latitudinal richness pattern with diversity peaking in lower latitudes and declining at the equator.
Behavior
Low mobility; sensitive to environmental shifts including changes in dissolved oxygen, temperature, and salinity. abundance in at least one (Chondrochelia dubia) shows negative correlation with monthly rainfall, with higher abundances in drier months.
Ecological Role
Indicators of environmental change in threatened coastal . The has been explicitly proposed as a suitable model for investigating diversity and distribution patterns in low-mobility crustaceans in response to environmental shifts.
Human Relevance
Used as bioindicators for assessing environmental impacts, threats, and conservation planning in coastal marine . One (Chondrochelia dubia) demonstrated recovery within two months after crude oil spill contact, suggesting that may complicate bioindicator utility in some contexts.
