Elasmobranchii (haaien en roggen) (sharks and rays) >
Orectolobiformes (Carpet sharks) >
Parascylliidae (Collared carpet sharks)
Etymology: Parascyllium: para (Gr.), near, i.e., presumed to be related to Scyliorhinus (now in Scyliorhinidae): skylion, Greek for dogfish or small shark. (See ETYFish); sparsimaculatum: sparsus (L.), sparse or few; maculatum (L.), spotted, referring to relatively larger (and hence fewer) spots than congeners. (See ETYFish).

Korte beschrijving
Morfologie | Morfometrie
Wervels: 45 - 46. Body yellowish-brown with relatively few, large, diffuse-edged, rusty-brown spots; collar-like saddle over gill region extremely faint. Head relatively large (length greater than 16% TL). Eyes large (horizontal diameter >11% HL). Pectoral fin large, anterior margin at least 10% TL. Dorsal fins relatively tall, erect with angular apices. Upper jaw with 43-49 teeth rows. Differs from P. ferrugineum and the more heavily spotted "P. multimaculatum" morph by having a larger eye (versus <11% HL); slightly more than tooth rows (versus 38-41); fewer and much paler spots on the body ; and more erect and angular dorsal fins (Ref. 41629).
Species is likely to occur deeper, 245-435. Oviparous (Ref. 50449).

Estimates based on models
Preferred temperature (Ref.

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
