Summary

catshark, Scyliorhinus stellaris

Seven key developmental stages of catshark Scyliorhinus stellaris inside the egg case

Stage 1 was characterized by no visible embryo. Stage 2 was identified as an early embryo formed on the surface of the egg yolk membrane. Stage 3 embryos had long tails and stage 4 embryos had externalized gill filaments. These filaments had shrunk by stage 5. In stage 6 the key feature was the loss of fin-folds, and in stage 7 the key feature was the fully consumed external yolk.
