Leachia dislocataRichard E. Young and Katharina M. Mangold (1922-2003)
A Leachia ...
- with a complex tubercule at anterior end of mantle strip displaced medially.
- with large adult having full;y sessile eyes.
- Length of cartilagenous strip 12-17% of ML.
- Complex tubercule at anterior end of strip displaced medially. image info
- On the adult eyeball, eight photophores comprise the outer series and the inner series (i.e., near the lens) consists of 7 photophores: two small photophores dorsal to the lens and five, three large organs alternate with two small ones, ventral to it. image info
The distinctive displaced tubercule on the cartilagenous strip is shared with Leachia pacifica.
The paralarva or the "pyrgopsis stage" has stalked eyes and few if any ocular photophores. The mature female has sessile eyes with a full compliment of photophores, relatively longer arms and photophores on the tips of arms III.image info
Ocular photophores are gradually added through growth.image info
The type locality is 32°35'N, 118°06'W, off southern California in the eastern North Pacific.
