Subject Area
Zum Beutefang lauert der gut getarnte Anglerfisch mit ausgeklappter Angel, einem Hautanhang des beweglichen 1. Rückenflossenstachels. Dieser hat Köderfunktion für andere Fische, die bei Annäherung verschlungen werden; anschließendes "Husten".
To catch prey the well camouflaged anglerfish lurks with its antenna, a skin appendix of the movable 1. dorsal fin spike. It serves as a bait for other fishes which are engulfed when approaching, then "coughing".
