> Acipenseriformes (Sturgeons and paddlefishes) > Polyodontidae (Paddlefishes)
Etymology: Polyodon: Greek, polys = a lot of + Greek, odous = teeth (Ref. 45335);  spathula: Polyodon, many toothed, perhaps due to the numerous gill rakers because adult paddlefish lack teeth, although young fish has many small teeth, and spathula meaning spatula, due to its elongated snout (Ref. 79012).

Short description आकृति विज्ञान | मौरफोमैटरिक्स

Snout long, canoe-paddle-shaped; gill cover with large, fleshy, pointed flap (Ref. 86798).

जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Usually inhabits water deeper than 1.2 m in slow-flowing large rivers, lakes, and impoundments (Ref. 86798). Feeds on plankton. The extended upper jaw (= paddle) may help to channel plankton into the mouth. Threatened due to over harvesting, habitat loss and pollution (Ref. 58490).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.2500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00430 - 0.00969), b=3.09 (2.98 - 3.20), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.45 se; based on food items.
लौटाव (Ref. 120179):  निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (tm=6-9; tmax=30).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
