Spiny Softshell
(Apalone spinifera)
Spiny Softshell
In Montana, spiny softshell
are present east of the
Continental Divide in
the Missouri River and
Yellowstone River drainages,
and some of the principle tributaries.
Spiny softshells occupy larger rivers and
tributaries, but can also occur in lakes,
ponds, rivers, pools along intermittent
streams, irrigation canals, and oxbows.
Conservation concerns include: habitat loss
and degradation, including barriers that
hamper movement of spiny
softshells; nest disturbance;
and incidental take from
anglers. Conservation strategies
include: conserving
major rivers in Montana; considering a
management plan for the spiny softshell
or including it in another comprehensive
taxonomic plan; protecting nest sites
from human disturbance; and thoroughly
documenting observations and incidental
take.
