Paedoclione doliiformis |
Paedoclione doliiformis is a species of sea angel, a small floating sea slug, a pelagic marine gastropod mollusk in the family Clionidae.
Paedoclione doliiformis is the only species in the genus Paedoclione. [2]
The generic name is a reference to the paedomorphic habit of this genus, which retains many larval features throughout its life. [3]
Paedoclione doliiformis was originally described by Charles Haskell Danforth in 1907. [1] It was not collected by zoologists for the next 61 years. [4] It was rediscovered in 1968 by Lalli (1972). [4]
The type locality of Paedoclione doliiformis is Casco Bay, Portland, Maine. [1]
The distribution includes St. Margarets Bay, Nova Scotia, the Gulf of Maine [3] [4] and possibly elsewhere.
Paedoclione doliiformis retains juvenile (larval) physical characteristics for the whole of its life. [4] This is called neoteny (a kind of pedomorphosis). [4]
The body length is up to 1.5 mm. [2] Paedoclione doliiformis has no shell. [2]
It is a gelatinous, mostly transparent pteropod, and it only has a shell in its embryonic stage.[ citation needed]
The orange visceral sac is confined to the anterior part.
Mating is carried out ventrally for mutual fertilization. The following spring, this results in a free-floating, gelatinous egg mass.
Eggs hatch after three days, and the shell is retained until the 11th day. [3]
Paedoclione doliiformis feeds exclusively on Limacina helicina and on Limacina retroversa, but solely on juveniles with shells smaller than 1 mm. [5] Its abundance is closely linked to that of its prey. [3]
