  • In Japan Pseudopythina tsurumaru is an up to 10.8 mm‐long commensal of the burrowing sea cucumber Protankyra bidentata, whereas in Hong Kong the same species is smaller and associated with the crab Hexapus anfractus, itself a commensal of P. bidentata. Japanese P. tsurumaru is a hermaphrodite tending towards protogyny maturing to a female when ≥7 mm, and entering the hermaphroditic condition when ≥9 mm long. In addition to normal euspermatozoa, the species produces 30–32 μm long and 7 × 8 μm… CONTINUE READING
