Behaviour

edit

Lepidopus caudatus is known to strand itself in winter months, likely due to being caught in currents when the fish migrate closer to shore for spawning.[2]

In a human context

edit

Lepidopus caudatus is a traditional food for the Māori people of New Zealand, known by the name pāra. The fish was not typically caught, but eaten as a supplementary food when schools washed ashore, especially common around Moeraki in Otago.[2] Māori traditionally believed that strandings were caused by the fish chasing the Moon, while early European settlers believed that frostfish purposefully chose to end their lives by stranding themselves.[2]
