Ecology of Chaceon affinis

Main Ref.	Abellán, L.J.L., E. Balguerías and V. Fernández-Vergaz, 2002
Remarks	Inhabits a variety of bottom substrates from mud to rock (Ref. 2708, 2725 and 2747); at a depth of 700 m and deeper; it prefers soft substrata (Ref. 2753), and it is found on seamount and escarpments (Ref. 2740). Recruitment of individuals occurs in the deepest substrata. Sacculina sp. is parasitic on this species, infecting individuals in deeper substratum around 1000 to 1100 m (Ref. 2677). Males parasitized by Sacculina sp. are feminized behaviorally and morphologically (Ref. 2694), whereas females are castrated (Ref. 2696). Epibionts Poecilasma crassa and Poecilasma aurantia are found on the exoskeleton of the crab (Ref. 2747 and 2752). This is an allopatric species (Ref. 2763).
