Bigeye thresher — size comparison — facts and sources

The bigeye thresher has very large eyes and an exceptionally elongated upper tail-fin lobe. It lives in tropical and temperate open-ocean waters. It changes depth daily, potentially spending daytime deeper and approaching the surface at night.

It eats fish and squid. Its long tail serves more than propulsion: strikes help stun prey. Large eyes suit low-light hunting as shoals and individual prey move between water layers.
