Max length : 86.4 cm TL hane/ej könsbestämd; (Ref. 26340); common length : 40.0 cm TL hane/ej könsbestämd; (Ref. 26999); publicerad maxvikt: 1.1 kg (Ref. 40637)
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 22 - 26; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 22 - 24. Dark brownish grey in color (Ref. 4389). During the course of development, fin is transformed into a suction disc (Ref. 35388). Deeper-bodied than Echeneis naucrates (Ref. 37816).
Usually associated with sharks but also attaches itself to other large fishes, sea turtles and even ships (Ref. 2850, 58302); found in gill chambers, fins and body surface (Ref. 5951). Sometimes free-swimming (Ref. 2850). Younger individual is more active as parasite pickers (Ref. 26938). Feeds on parasitic copepods (Ref. 35388).
