aboral organ
A
- rudimentary brain
- controls the comb rows
- gravity sensing
3
Q
collocytes
A
secretes a sticky substance for prey (spin-capture)
4
Q
ctene rows
A
- comb rows (8 rows)
- fused cilia used for locomotion
5
Q
ciliary rosettes
A
canals that help transport nutrients to muscles in the mesoglea (may also help remove wastes from the mesoglea, or buoyancy)
6
Q
photocytes
A
contains calcium activated proteins that cause bioluminescence
