Subject Morphology
Notes The dorsal six arms have dark tips; the insert is an enlargement of one of the arm tips. The ventral arms have lost their tips. The heavily pigmented region is presumably photogenetic and, if so, the pigment would withdraw when light is emitted. Arm tips bare of suckers are characteristic of immature females but not males. We have examined a mature male and it lacks arm-tip photophores. The sex and state of maturity of the specimen illustrated below from Joubin, 1898 are unknown. Presumably the arm-tip photophores are characteristic of mature or nearly mature females.

Tree of Life Media Use Survey

The information you provide in this survey will help us improve the ToL media collection. We are trying to find out what kinds of people are using our images, movies, sounds, etc., what they are using them for, and what we could do to make the collection more useful to them.

How do you use this image? If you are a teacher/professor/librarian: At what level do you teach/learn? How old are you? Where in the world do you live/learn/teach? Do you have any suggestion on how we could improve the Tree of Life media collection?
