Marbled Salamander (Ambystoma opacum)

The Marbled Salamander is a visually appealing species inhabiting the deciduous forests in the eastern United States. This species demonstrates sexual dimorphism - females typically showcase light grey bands, while males present strikingly white ones.

They live near bodies of water, frequently burrowing under rocks or logs. When threatened, they curl their tails to expose their bright underside, secreting a mild toxin. Other defense mechanisms include the coiling of bodies and the lashing of tails.
