Following this protocol, the mesoglea turns to a deep blue color while the cytoplasmic elements and epithelia differentiate to pink-reddish tones, clearly highlighting loaded nematocysts structures (e.g., mesenterial filaments,
acontia, acrorhagi).
In early transmission electron microscopy (TEM) studies of nematocysts from sea anemone acontia and tentacles.
Tentacles and acontia were cut from each individual.
For this
Acontia moth (above), looking gross is great!
"When I was on vacation in Maryland I found the larvae of a looper moth - the curve-lined
acontia - that really was neat.
As another example, larger defensive nematocysts in the
acontia of Metridium farcimen reflect the relatively higher predator densities in its subtidal habitat, by comparison with the smaller acontial nematocysts associated with the shallower habitat of M.
When attacked, the anemones contract and extrude many long, thread-like mesenterial filaments (the
acontia) through the mouth and column wall (Hyman, 1940).
The scaffolding in orbitotemporal region changes with the body-plan, presenting reductions of some cartilages in serpentiform skinks like Lygosoma sp.,
Acontias meleagris and Chalcides sepsoides (Pearson 1921; Bellaris & Kamal 1981).
