GBIFID: 4994142540; Occurrence Remarks: Some of you have asked about this picture. THe Salamanders are in the creek that runs about ten feet in front of my home. Having the four sons I do they often go into the creek looking for Salamanders in and under the rocks. They like to see the variance in morphology and other interesting things. When they have a bunch like this they call me and ask for a picture as I took here. They then let them all go back into the rock where they found them until the next time they are bored enough to get into the creek. SO this is not a natural aggregation as found in the picture but more a picture of all the salamanders caught in a ten-foot-long part of the creek in about an hour.;; Coordinate Uncertainty in Meters: 2.00000.

GBIFID: 1562943917; Occurrence Remarks: Metamorphosed adult, 82/125mm; 18g. Water ~10.6C. Apparently I flushed this DITE from his resting spot. I just happened to look behind me and saw something zip from the water, out onto a log, and â€œjumpâ€ from the log to rocks ~1m below, scurry across the flat rocks to the stream edge and attempt to wiggle into crevices there. Thankfully it didnâ€™t get very far and I just lifted a couple stones to capture the salamander. Beautiful. Golden sparkley with dark brown marbling. Small white spots on lower sides and sides of belly. No dark tips on toes. The pools and falls here are created by capture of rocky substrate by large logs in channel. Stream width ~3m. Depth are ~20cm, up to ~35 in this spot. Didnâ€™t see where DITE came from. 20% canopy, pretty sunny. Diverse rock sizes. Mostly gravel-cobble.;; Coordinate Uncertainty in Meters: 10.00000.

GBIFID: 2626339754; Occurrence Remarks: Exceptionally poor iphone photographs aside, I saw this salamander quite well. I had 8x42 binoculars with me that allowed for close study without disturbing it. It was in only about 6inches of water, under some woody debris that has accumulated in a small rifle in the creek, just downstream from the footbridge on the main trail through the ravine and adjacent to a sizeable seep on the north bank. The salamander itself was neotenic, and very large, I estimate ~20-25cm in length. Large, broad head, large eyes, fairly small gills. Body was long, fairly uniformly brown, with costal folds. Toes were short and stubby. Head was not noticeably wider than the rest of the body, giving it a very girthy appearance. I will admit, I am have limited experience with salamanders of the PNW as Ive only lived in the region for around a year. However, from my understanding D. tenebrosus is one of the only large, stream-breeding salamanders in the Seattle area. It lacked the long gills of an Ambystoma sp, was too large for a Red-backed or Ensatina, and the smooth skin, overall size, and uniform brown coloration eliminates rough skinned newt. The habitat (cold, quickly moving stream near a seep in a densely wooded ravine) fits D. tenebrosus quite well too, despite being in the middle of NE Seattle! I will definitely be returning to this location to attempt better documentation.;; Coordinate Uncertainty in Meters: 24.00000.
