Efts (larval salamanders) have long feathery gills and are brown or olive green in color, with yellow, green, or black mottling along their dorsal-finned tail (Stebbins and McGinnis 2012, California Herps 2019). Terrestrial adults require moist crevices in logs or rodent burrows in the ground for shelter from weather and predators. Long-toed Salamanders mostly live underground in rodent burrows and … It's motion is slowed down at the end to showoff its graceful movement. This salamander is not included on the Special Animals List, meaning there are no significant conservation concerns for it in California according to the California Department of Fish and Game. The aquatic form is diurnal whereas the salamanders inhabiting the land are … The juveniles are 16– 105 mm long from their snout to vent. Eggs & Larvae. Habitat: AGONISTIC BEHAVIOUR IN LARVAE OF THE NORTHWESTERN SALAMANDER (AMBYSTOMA GRACILE): THE EFFECTS OF KINSHIP, FAMILIARITY AND POPULATION SOURCE by SUSAN C. WALLS1,2,3), CHARLES S. CONRAD4), MICHELLE L. MURILLO5) and ANDREW R. BLAUSTEIN6,7) (1Department of Biology, The City College of The City University of New York, Convent Avenue at 138th Street, New … The egg masses are laid in water about 0.5– 2 meters below the surface. Metamorphosed females lay 30 - 270 eggs in masses that are roughly the size of a small grapefruit , and attach them to underwater shrub branches, grass, or aquatic plants. The 12 fish lakes with observed larvae were significantly lower in median elevation, larger in median surface area, and deeper in median maximum depth than the fishless lakes. The Northwestern Salamander is distinguishable from other salamanders by its uniform graybrown coloration, parotoid glands, and glandular ridge along the top of the tail. i currently have four northwestern salamander larvae! 3) Eggs are often laid on submerged woody material. Larvae are pond-adapted, brown or olive green in color, with dark pigment along the base of the dorsal fin, and long feathery gills. Species Description. Enlarge Image . In California, found in moist habitats along the Pacific coast, including grasslands, woodlands, and forests. Larvae: 7.5-15cm (3-6in) long, body is brown, olive green or light yellow on top, sides are blotched (sooty) with yellow spots, glandular strip on tail fin. Leaf litter and cover objects, such as logs and rocks, are important microhabitats where the salamanders forage and seek shelter. Larvae have been reported to be restricted to shallows in lakes with fishes, but adult and larval northwestern salamanders are distasteful to fishes and bullfrogs, sometimes allowing coexistence (Leonard et al. In some cases, Ambystoma gracile do not undergo metamorphosis from the aquatic larval stage to a terrestrial adult form. Four-toed salamander larvae require slow-moving or still water without fish, while juvenile and adult salamanders require shaded, moist terrestrial microhabitat typical of closed-canopy forests with leaf litter, moss, and decaying logs [3,17,32,59,88]. i currently have four northwestern salamander larvae! Aquatic larva, King County, Washington. An adult Northwestern Salamander paedomorph (still has gills and lives in water permanently - never transformed to live on land) swims around in a shallow pan of water. Egg mass. This salamander appears to be transforming from an aquatic to a terrestrial existence. A look at a breeding pond during the February breeding season, including several egg masses, and a paedomorph in the water at night. This species remains common in much of their range, though they have lost suitable habitat through urbanization and agricultrual development, and have undergone temporary declines in areas of clearcut logging. Gray/brown color, smooth skin, costal grooves evident, large paratoid glands behind eyes, back may have flecks of green or yellow. This is a little video dedicated to northwestern salamanders! A large, heavy, stout bodied lunged salamander with a short broad rounded head, blunt snout, small protuberant eyes, moist smooth skin with conspicuous oval parotoid glands behind the eyes and on the tail ridge. 1983). 2) A second jelly coat gives the egg mass a wavy appearance. larvae Larvae are 7.5-15cm (3-6 in) long, body is Larvae mature in 12-14 months. Northwestern Salamander. A member of the Mole Salamander family (Ambystomatidae) whose members are medium to large in size with heavy, stocky bodies.
