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.

The Gills of the Coelacanth, Latimeria chalumnae, a Study in Relation to Body Size

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.

Observation of the first juvenile Indonesian coelacanth , Latimeria menadoensis from Indonesian waters with a comparison to embryos of Latimeria chalumnae

Clear differences in the first ontogenetic stages of the two species, although adults have almost the same morphological features are indicated, are indicated.

A NEW COELACANTH (ACTINISTIA, SARCOPTERYGII) FROM THE JURASSIC OF FRANCE, AND THE QUESTION OF THE CLOSEST RELATIVE FOSSIL TO LATIMERIA

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.

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 recent

Viviparity and the maternal-embryonic relationship in the coelacanth Latimeria chalumnae

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.

The gross morphology of Latimeria gills is characterized by well developed interbranchial septa that extend almost to the tips of the filaments of each hemibranch and among living fish resembles most

The Coelacanth Latimeria chalumnae

The most important distinguishing feature of these fishes is the division of the neurocranium into two parts, an anterior, ethmo-sphenoid portion and a posterior, otico-occipital portion with an intracranial joint between them.

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.

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.

The subcephalic muscle of Latimeria probably was derived from one or more anterior body myomeres such as occur in Recent polypterids. In early gnathostomes this musculature primitively may have
