Diet
Marine
organisms, worms and other molluscs.
Venom
The venom
consists of numerous neurotoxic peptides and can result in the
death of humans. The venom acts pre- and post-synaptically
to give rise to neurological symptoms such as
weakness, lack of co-ordination and disturbed vision,
hearing and speech . Severe envenomation may result in death
secondary to respiratory muscle paralysis. Less common systemic
symptoms include nausea and generalized pruritis. Local symptoms
of pain, swelling and numbness are common.
Pressure immobilisation first aid should be applied and left in place
until resuscitation facilities are available. This is a medical
emergency. Assisted ventilation may be needed.
- Tetanus prophylaxis should
be updated if required.
- There is at present no
antivenom for cone shell stings.
