This species is often smaller, but appears practically identical to T. imitata - and is best distinguished based on location (this species only found in South Australia and Western Australia). It differs from T. testacea in lacking the small dorsal fin on the tail. Most commonly seen in shallow sheltered bays near seagrass beds.
