Status: Iowa – Declining

Size at hatching, 7 -14 mm; at metamorphosis, 48 - 61 mm total length

field mapThe Small-mouthed Salamander is found in the southern third of Iowa. The adult of this species resembles its common name in having a relatively smaller head and mouth compared with other mole salamanders. The eggs are laid singly or in small loose clusters on vegetation or debris in ponds (rarely in streams). Larger masses may be sausage-shaped. The larvae are similar to other mole salamanders but have pigmentation on their chin. They are a uniform brown after metamorphosis.
