Larval development of the Patagonian brotula Cataetyx messieri (Pisces, Bythitidae) from fjords of southern Chile
Larvae of Cataetyx messieri (Bythitidae) are described from 14 individuals (12·3–27·9 mm body length) collected in deep fjords and channels of the inland sea of southern Chile (41–55° S), between 137 and 604 m depth. The larvae are elongate, with a large, flattened mouth and a coiled gut. They are lightly pigmented and show three distinctive features: a band of melanophores from the snout to the opercle, melanophores spread over the dorsolateral surface of the stomach and the intestine and a band of melanophores on both dorsal and ventral margins of the tip of the tail and adjacent finfold.
