Amblyopsidae (Cavefishes)
Etymology: Typhlichthys: Greek, typhlops = blind + Greek, ichthys = fish (Ref. 45335); subterraneus: subterraneus meaning beneath the earth (Ref. 10294).

North America: portions of Alabama, Georgia, Tennessee, Kentucky, Indiana, Missouri and Arkansas, U.S.A.
サイズ / 重さ / 年齢
Maturity: Lm ? range ? - ? cm
Max length : 9.0 cm TL オス/雌雄の選別がない; (Ref. 10294); common length : 5.0 cm TL オス/雌雄の選別がない; (Ref. 12193); 最大記録サイズ: 4 年 (Ref. 10294)
背鰭 (合計) : 7 - 10; 臀鰭: 7 - 10; 脊つい: 28 - 29. Pink-white. No eyes (vestigial eye tissues under skin). Large, broad head. Caudal fin with 0-2 rows of papillae (Ref. 5723) and a vertical basal row (Ref. 10294); 10-15 branched caudal rays (Ref. 5723).
Adults inhabit subterranean water (Ref. 5723). Found in caves which are near the water table and are therefore more uniform than other amblyopsid caves (Ref. 34868). Feed mainly on copepods, amphipods and isopods (Ref. 10294). Eggs are carried in gill chambers of females (Ref. 205).
Life cycle and mating behavior

Incubates eggs in gill chamber of females (Ref. 205). Fecundity is very low, perhaps fewer that 50 ova per female (Ref. 10294).

50 = 1.0088 [Uniqueness, from 0.5 = low to 2.0 = high].
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.

栄養段階 (Ref.
69278): 3.3 ±0.37 se; based on food items.
Generation time: 2.6 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
