Pacific Sea Snake

Identification and appearance

The Kimberley sea-snake guide describes a large-headed form with numerous dark bands across the body and tail. These are broad clues only: sea-snake colours and body forms vary, and the identity of some historical Australian records remains uncertain.

Other names

Annulated Sea Snake, Large-headed Sea Snake

Typical length

AROD reports an average size of about 140 cm; no separate maximum is given.

Key identification features

• Large-headed, banded form in the Kimberley guide
• Marine snake of northern Australian waters
• Historical identifications require caution

Where it is found

Current Australian records in the consulted databases are associated with Queensland and the Northern Territory marine waters; historical synonymy may affect the record.

Reproduction

Live-bearing.

Medical significance

Treat any suspected bite as an emergency, call 000 and do not wait for identification.

What to do if you encounter one

Keep your distance in the water or at shore and do not approach, chase or handle the snake. Do not enter the water to inspect it. If a bite may have occurred, call 000 immediately and follow Australian snakebite first-aid guidance.

Taxonomy notes

AROD notes possible synonymy with Hydrophis cyanocinctus; the current name is retained here without treating that relationship as settled.
