Dissection ofa specimen of Latimeria chalumnae in the American Museum of Natural History revealed that it is a gravid female containing five advanced young, averaging 317.8 millimeters long. Each has a large yolk sac with no apparent connection to the surrounding oviducal wall. We conclude that Latimeria is ovoviviparous. Fig. 2. Yolk-sac young of Latimneria chalurnnae, the sccond of five found in a temale 1.6 m long at the American Museum of Natural HistorN. Unretouched photograph shows fins… Expand

The Gills of the Coelacanth, Latimeria chalumnae, a Study in Relation to Body Size
TLDR
It is concluded that this more extended study of gill morphometrics of Latimeria confirms predictions made from earlier comparative studies regarding the life habits of this fish which have also been confirmed by direct observation using submersibles. Expand
New scale analyses reveal centenarian African coelacanths
TLDR
P polarized light microscopy is used to study growth on scales and demonstrates for the first time nearly imperceptible annual calcified structures (circuli) on the scales and suggests that circuli are indeed annual, thus supporting that the coelacanth is among the longest-living fish species, its lifespan being probably around 100 years.

Observation of the first juvenile Indonesian coelacanth , Latimeria menadoensis from Indonesian waters with a comparison to embryos of Latimeria chalumnae
− The juvenile of Indonesian coelacanth, Latimeria menadoensis is here described for the first time in detail with comparison to embryos of Latimeria chalumnae. The juvenile was found in freeExpand
A NEW COELACANTH (ACTINISTIA, SARCOPTERYGII) FROM THE JURASSIC OF FRANCE, AND THE QUESTION OF THE CLOSEST RELATIVE FOSSIL TO LATIMERIA
TLDR
A cladistic analysis suggests that the new species is the fossil sister taxon to Latimeria, but this close relationship is weakly supported and Nevertheless, Wenzia latimerae belongs with confidence to the Latimeriidae. Expand
The ecology and conservation of the coelacanth Latimeria chalumnae
SynopsisStudies on the ecology of the living coelacanth, Latimeria chalumnae, are reviewed and assessed. Early predictions on the life history of the coelacanth have proved to be accurate but recentExpand
Viviparity and the maternal-embryonic relationship in the coelacanth Latimeria chalumnae
SynopsisEmbryos of Latimeria chalumnae develop in well-vascularized compartments in the uterine region of the right oviduct. Compartments conform to the shape of their embryos and yolksacs; theyExpand
Viviparity and the maternal-embryonic relationship in the coelacanth Latimeria chalumnae
TLDR
During the early and middle phases of development, embryos must be lecithotrophic, using their yolk reserves, with oophagy of fragmented supernumerary eggs as the most probable source of additional nutrients. Expand
The ecology and conservation of the coelacanth Latimeria chalumnae
TLDR
The coelacanth is a highly specialised, precocial fish which occupies a unique place in biology and international efforts should continue to be made to understand and conserve this remarkable fish. Expand

Early growth stages in coelacanth fishes.
TLDR
It seems more reasonable to interpret this fossil specimen from the Upper Jurassic of Solnhofen, southern Germany, as a cannibal that had just swallowed two young of its own kind, and this interpretation is favoured by the position of the two specimens. Expand
Latimeria chalumnae: Reproduction and Conservation
TLDR
It is believed that a reconsideration of the reproductive mode in coelacanths is in order following the conclusion that the coelacanth, Latimeria chalumnae, is oviparous. Expand
