Morphing Tiger Salamanders

It’s the time of year when we seine ponds in search of California Tiger Salamander larvae. We found quite a few last week so I thought this would be a good time to display a few photos of salamanders in different stages of development.

In this first photo, the larvae is showing signs of leg muscle development and first signs of diminished dorsal fin.

The dorsal fin on this larvae is further reduced, the leg muscles are improving and some yellow spots are appearing near it’s belly. It’s gills appear to be diminished in size.

This larvae is further along than the others. Gills are gone, dorsal fin gone and coloration is more like an adult. Assuming they avoid predators, these larvae will leave the pond in the next couple weeks.
