List of Delaware's Reptiles & Amphibians

Delaware's Reptiles & Amphibians
This list contains all of the Reptiles and Amphibian species which may be found in the state of Delaware. Some species are extremely rare, federally and / or state protected, and may be unlikely to be encountered in the wild.

Delaware is home to 20 species of Snakes, though many species are rarely seen due to their reclusive habits or low and fragmented population numbers. 
  • Eastern Garter Snake
  • Northern Water Snake
  • Eastern (Black) Rat Snake    
  • Northern Black Racer

The best way to observe many of Delaware's Turtle species is to look along the edge of ponds and rivers on a warm day, where many species bask in the sun on the banks, on rocks, or branches and fallen trees overhanging the water. There are 10 Turtle species found in Delaware.

  • Loggerhead Sea Turtle endangered
  • Kemp's Ridley Sea Turtle endangered
  • Atlantic Hawksbill Sea Turtle endangered
  • Green Sea Turtle endangered

Many of Delaware's Frogs are seasonally active, meaning you're most likely to see and hear them in the Spring and early Summer when they gather in mass numbers to breed. Delaware is home to 13 species of Frogs.
  • Southern Leopard Frog
  • American Bullfrog
  • Fowler's Toad
  • Northern Green Frog
  • Northern Cricket Frog
  • American Toad
  • Northern Spring Peeper
  • Gray Tree Frog 
  • Green Tree Frog
  • New Jersey Chorus Frog
  • Pickerel Frog
  • Wood Frog
  • Eastern Spadefoot  
  • Cope's Gray Tree Frog
  • Carpenter Frog
  • Barking Tree Frog endangered
Delaware is home to 3 species of Toads. Like Frogs, Toads are seasonally active - but they're also fairly common throughout the non-breeding season (except for the Spadefoot) due to their higher toleration of dry conditions. Typically the American Toad is found in the Piedmont region (New Castle county), and the Fowler's Toad takes over throughout Kent and Sussex counties. The Spadefoot Toad is rarely seen, only after very heavy rains does it come out of the ground to breed. Some years they don't emerge at all, if the rains aren't good enough.
  • Fowler's Toad
  • American Toad
  • Eastern Spadefoot Toad
Most of Delaware's Salamanders are rarely seen due to their subterranean and reclusive lifestyles or are generally uncommon. The best time to observe the majority of our salamanders is during their breeding seasons when they migrate from their woodland homes and hibernation areas to the temporary vernal pools in which they breed. There are 11 species of Salamanders documented to inhabit Delaware.
  • Northern Red-backed Salamander
  • Spotted Salamander
  • Marbled Salamander
  •  Northern Two Lined Salamander
  • Red Spotted Newt
  • Four-toed Salamander
  • Northern Dusky Salamander
  • Northern Red Salamander
  • Long-tailed Salamander
  • Eastern Mud Salamander
  • Eastern Tiger Salamander endangered     
Four species of Lizards are found in Delaware. Best observed while they are basking on trees, rocks, concrete and other surfaces during warm, sunny afternoons.
  • Common Five-lined Skink
  • Eastern Fence Lizard
  • Ground Skink
  • Broad-headed Skink

  1. It would be really nice to have accompanying photos so we could ID the species as we see them.

    1. Good point. That's been a primary goal of mine since starting this site, and I hope to get it completely finished within the next year. The setback is I don't want to run into any ownership issues by using someone else's images or videos; to avoid any issues like that, I'm using my own images for the site - it's just taking a bit of time to get all of those shots. I have 60-70% of what's needed for this page, and I'm going to go ahead and update with what I have soon. I was hoping to get all of the images needed this year, but with cold weather coming in it looks like I'll have to wait to get the last bunch until next spring. When it's complete, this page will have images next to each species name and detailed information when an image or name is clicked on.

      Thanks for the feedback, and I'm sorry if you had trouble finding anything because of the issue. I'm still working on the page, things will run smooth eventually. Check back soon, or send me an email ( if you have any questions.
