Document Summary
Live in the deep sea (200 400 m)and live predominantly in salt water. Dots present on them are photophores that glow in the dark. During the summer they migrate from deep seas to shallow intertidal shores to breath (this is where they are studied tidal zones) Males burrow (form cavities) under rocks in order to bread (most of their time is spent under such rocks) Males once they find their mating grounds will began to sing that sound similar to phone vibrations (humming) in order to attract females. Well adapted muscles on the side of their swim bladder help produce these vocalizations (one of the fastest twitching muscles in invertebrates) Females do not vocalize as much and have significantly smaller organs and lack required specific muscles for vocalization. The females lays and glues her eggs to the underside of the rock in which the male has burrowed. Males guard the eggs for about 2 months.
