Declared extinct and then later revised as "possibly extinct" due to insufficient data, the smooth handfish is thought to have been once commonly found off the coast of Tasmania --- so much so that it was one of the first species noted by European colonists. Using pectoral fins to walk across the seabed, the fish were described by Zoe Kean on the Guardian's Age of Extinction channel as resembling "grumpy ageing punks, each spotting a dorsal fin over its head like a mohawk, bulging eyes and a cantankerous expression." Known primarily from a sole type specimen collected during François Péron's 1802 colonial survey of Australia, this species of handfish is thought to be the first modern marine fish to have gone extinct, falling prey to environmental changes and unsustainable scallop harvesting and trawl fishing in the nineteenth and twentieth centuries.
