Pacific Pond Turtle

Description
Adults of the Pacific Pond Turtle grow to a maximum of 19 cm. They have a low carapace which is usually patterned with faint spots or lines on a dark olive to blackish background. The plastron is yellowish, usually with dark blotches.

Confusing Species
They are similar to the Painted Turtle but it has yellow lines on the head and limbs.

Distribution
They were introduced into Burnaby Lake in British Columbia. They extend as far south as Baja California in the United States.

Habitat
They are found in ponds, marshes or streams with a rocky or muddy bottom.

Reproduction
Mating and oviposition occur between April and August depending on locality. Clutch size varies from three to eleven eggs.

Natural history
They are highly aquatic and will bask on logs, cattail mats and mudbanks. They are primarily carnivorous, eating insects, worms and fish but will eat carrion and some plants.

Conservation Concerns
The Pacific Pond Turtle was never endemic to Canada. It was introduced into Burnaby Lake and has subsequently been extirpated from Canada.
