Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Worldwide in warm seas. Western Indian Ocean: including Reunion and Mauritius (Ref. 33390). Eastern Pacific: off San Francisco in California, USA to Chile, but rare north of Baja California in Mexico. Western Atlantic: Florida in USA and Gulf of Mexico to Brazil (Ref. 7251). Eastern Central Atlantic: St. Paul's Rocks (Ref. 13121).

Host specific on manta rays, but occasionally attaches to sharks. Often occurs inside gill chamber and mouth of host. Also attaches itself to black marlin, Makaira indica, of the Indo-Pacific Region (Ref. 7251). Rarely free-swimming (Ref. 10791). Used in Chinese medicine (Ref. 12166).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5352 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00273 (-0.19728 - 0.20275), b=3.14830 (3.03814 - 3.25846), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.3 ±0.5 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 10,000).

Vulnerability (Ref. 59153): Low to moderate vulnerability (27 of 100) .

Price category (Ref. 80766): High.
