Discoveries in Scottish Seas: Fish Without a Face - Amphioxus
by Christine Dell’Amore
A brainless “fish” without a face, the elusive Amphioxus was seen in the waters off Tankerness. The rarely seen species is not a true fish—it’s “an evolutionary step” between invertebrates and vertebrates, said Mike Robertson, senior marine ecologist for the Scottish government.
For instance, Amphioxus has a nerve cord—a precursor to a proper backbone—Robertson said. The white structure that resembles a spine is actually the species’ gonads, which are located in its belly.
