Histological sections of the cephalopodal region of Achatina fulica. a Control, melanin deposition (black arrow) and melanin production (white arrow) in the tissue. b 1 dpi, L1 surrounded by cellular infiltrate (dashed arrow) with the presence of melanin (black arrow). c 8 dpi, the presence of melanin (black arrow) and melanin production (white arrow). d 13 dpi, larvae involved in cellular infiltrate (dashed arrow), with a low amount of melanin (black arrow) in the surroundings. e 30 dpi, larvae involved by less dense cellular infiltrate (dashed arrow) and low amount of melanin in the surroundings (black arrow). Scale-bars: 25 μm
