Padella cephaloptera, a so called arrow worm

Post by Franz Neidl »

Padella cephaloptera is an animal from the Chaetognatha. It was circa 5 mm long.
The Arrow Worms are hermaphrodites.
The paired ovaries are in the posterior part of the trunk. See picture Nr.1. Unfortunately the eggs in my picture are rectangulare, because of the weight of the coverslip. (Next time I will take a picture without a coverslip!)

The paired testes you can see near the tail. See picture Nr. 2.
