how long does it take for painted turtles to hatch
Painted turtle Incubation lasts 72–80 days in the wild[45] and for a similar period in artificial conditions.[49] In August and September, the young turtle breaks out from its egg, using a special projection of its jaw called the egg tooth.[53] Not all offspring leave the nest immediately, though.[45] Hatchlings north of a line from Nebraska to northern Illinois to New Jersey[54] typically arrange themselves symmetrically[55] in the nest and overwinter to emerge the following spring.[45]
Spawn (biology) After mating, the fertilized eggs of the California spiny lobster are carried on the female's pleopods until they hatch, with between 120,000 and 680,000 carried by a single female.[50] The eggs begin coral red, but darken as they develop to a deep maroon.[51] When she is carrying the eggs, the female is said to be "berried". The eggs are ready to hatch after 10 weeks,[50] and spawning takes place from May to August.[52] The larvae that hatch (called phyllosoma larvae) do not resemble the adults. Instead, they are flat, transparent animals around 14 mm (0.55 in) long, but as thin as a sheet of paper.[53] The larvae feed on plankton,[51] and grow through ten molts into ten further larval stages, the last of which is around 30–32 mm (1.2–1.3 in) long.[53] The full series of larval molts takes around 7 months, and when the last stage molts, it metamorphoses into the puerulus state, which is a juvenile form of the adult, though still transparent.[53] The puerulus larvae settle to the sea floor when the water is near its maximum temperature, which in Baja California is in the fall.[54]
