Hi all,
While reading the American Society of Ichtyologists and Herpotologists
76th
Annual Meeting catalog, I came across the following information on
Elassoma
zonatum:
"Authors: Echelle, A.F., and Echelle, A.A. (AFE,AAE) Zoology Dept.,
Oklahoma
State University, Stillwater, OK 74078 USA
Breeding behavior in the banded pygmy sunfish (Elassoma zonatum)
Breeding behavior of banded pygmy sunfish is described and illustrated
with
video. The courtship sequence is complex and accompanied by color pattern
changes in the male. The male, initially in an aggressive state, displays
to
the female with "wiggle-waggle", a conspicuous motion involving all the
fins.
Wiggle-waggle continues during leading behavior as the male repeatedly
swims
up and down while moving to a predetermined spawning site over a patch of
vegetation. If the female follows, the male switches to pointing behavior
consisting of intense trembling in a head-down, vertical position, snout
directed toward the spawning site. With the female over the site, the
male
begins nudging her ventrolaterally near the anal fin and genital papilla.
The
female then starts releasing eggs and the male performs sidewise and
forward
twitches during which milt is presumably emitted. There is no nest
construction nor parental care beyond male territorial defense. (Session
54,
Tuesday June 18, Vieux Carre A, 4:00.) "
