Mass Strandings of Whales and Dolphins

Mass strandings: situations where groups of whales, dolphins, etc. swim onto the beach and die.

Common in areas where the 31 can change quickly.

Several other theories:

Parasites

e.g. some  parasites  can affect  marine animals' 32, which they depend on for navigation.

Toxins

Poisons from  33 or are commonly consumed by whales.

e.g. Cape Cod (1988) -whales were killed by saxitoxin.

Accidental Strandings

Animals may follow prey ashore, e.g. Thurston (1995)

Unlikely because the majority of animals were not 34 when they stranded.
