Shalom all,

We had occasion last night to PM a young male Ziphius (4.2 m long) which
stranded alive and died within minutes of reaching the beach. It was very
emaciated (all vertebral tips showing) and its stomach contained a total of
4.5 Kg of plastic debris with few interspaced cephalopod beaks. It may be
common practice for weak and hungry animals to seek to fill their stomach
with easily accessible floating objects, although I am not sure what they
did it with prior to the plastic age (algea?).
Incidently, does anyone know at what age/length do the teeth erupt in a
male Ziphius? This one had no signs of teeth.

Kind Regards,
