1. The septa in these corals are often arranged about a six-fold symmetry so that they are fundamentally different from the Rugosa.
2. In rugose corals the septa usually have a basic four-rayed symmetry in each corallite.
3. As the brood grows, workers chew through septa in the shoots and kill or seal off other queens, after which the whole tree is taken over.
4. A massive coral with irregular knobs, composed of corallites with a diameter less than cm, with polygonal outlines, and with about twelve prominent septa like the spokes of a wheel.
5. These have much smaller corallites usually only a millimetre or two across, and the septa typical of rugose corals are absent or inconspicuous.
6. The most obvious of these building elements are plates arranged radially, looking like the spokes of a bicycle wheel in section ( septa ).
7. The chambered shell ( phragmocone ) is less conspicuous - it is tucked into the broad end of the fossil guard, where the series of closely-spaced septa reveal the cephalopod nature of these otherwise somewhat featureless fossils.
8. Long meandering corallites with thin septa form a dense meshwork to give this coral an appearance like the labyrinth implied in the specific name.
9. Ammonoids differ from nautiloids in the suture lines being wavy or crimped; this of course reflects an elaboration of the outer part of the walls (septa) separating the chambers in the earlier part of the shell.
10. I he septa that line the edges of the corallites are here very short.
