The Eastern Jumping Blenny has a slightly compressed body and a scaleless head with a steep snout profile. It has three separate dorsal fins, a long-based anal fin and large pectoral fins.
The species is usually grey to greenish-yellow above and pale below. It often has dark saddles across the back and small pale spots.
It grows to 12 cm in length.
Two species of Lepidoblennius occur in Australian waters. The second is the Western Jumping Blenny, L. marmoratus. The two species have separate distributions - the Western Jumping Blenny is found in South Australia and Western Australia. They can be separated by the broad connection of the fin membrane between the third and fourth dorsal spines in the Eastern Jumping Blenny, versus membrane connected only near the base of the fourth spine in the Western Jumping Blenny.
The Eastern Jumping Blenny is endemic to Australia. It occurs in temperate marine waters from the central coast of Queensland to southern Victoria.
