Worldwide in tropical and warm waters. Western Atlantic: Texas, USA to Brazil. Eastern Pacific: Vancouver Island in British Columbia, Canada to Chile (Ref. 2850). Mediterranean reports doubtful (Ref. 13729).
Oceanic, mostly in warm seas. Attaches itself only to whales and porpoises (Ref. 7251). One adult couple was recorded attached to the same individual spinner dolphin for a period of about 3 months (Ref. 50801).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5352 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00275 (0.00111 - 0.00682), b=3.15 (2.93 - 3.37), based on LWR estimates for this Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±0.4 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
): Moderate to high vulnerability (45 of 100) .
