Description
Physical Description
Species Ichthyomyzon fossor
Body: Mouth
and Snout: Sucking disk in adults
, flexible
hood
in juveniles
,
no jaw. Teeth small and blunt
in adults; none in juveniles. No barbels
.
This nonparasitic species has a sucking disk that is about the same
in diameter as its body. Gill openings consist of seven circular
holes
. Body Pattern
: Solid color. Dark grayish brown or gray on dorsal
surface and flanks, grading
to light gray/brown, silvery, or off-white
ventrally. Lateral
pores
unpigmented. No scales
. Body Shape
: Elongate
,
cylindrical, flexible body. Typically 100-135 mm (4-6.5 inches) with
a maximum of 171 mm.
Ammocoetes
may reach slightly longer
lengths
than adults, with shortening (up to 10%) occuring in transformation
to adulthood.
Fins
: Rounded
tail. Dorsal fin with no spines. No anal
, pectoral
,
pelvic
, or adipose fins
. The dorsal fin is continuous (not bilobed
).
Distinguishing characteristics: Eel-like body and sucking disk identify
the lamprey family
. First and second dorsal fin broadly connected.
Lateral pores unpigmented. Adult only: maximum disk diameter lesser
than maximum body diameter; supraorbital
lamina teeth cusps close
together, inner circumoral teeth
unicuspid
. Maximum length
171 mm.
46-56 trunk
myomeres. See also similar species information.
Breeding adults: Lampreys
spend most of their lives as ammocoetes.
They transform
to the adult form in the fall
, cease feeding, breed
in the spring
, and die. The adult form is the breeding form. No photo
because it s the same.
Juveniles: Ammocoete form. Distinguished from adults based on head
and mouth characteristics. Ammocoetes lack eyes, have a hood-like
covering of the mouth withour a papillary
fringe
, and have soft sieve
like tissue
in the mouth. Ammocoetes are brown to gray-brown without
eyes.
Habitat
Inhabits clean, clear gravel riffles and runs of small rivers . Ammocoetes occur in quiet water over sand , silt and debris .
Biome: Marine .
Biology
Diet
Non-parasitic, the adults and possibly the larger ammocoetes in the resting stage do not feed [1].
