I have this planet that's 1.8 times the size of Earth on an eccentric orbit around a star that's 0.2 times the size of the sun. Its apses often change due to the influence of a neighboring gas giant. At apoapsis, the entire planet is covered in oceans with only the highest peaks poking out as tiny islands and a small continent. At periapsis the entire ocean is reduced to a flat dry land. All of this cycle within the planet's year of about 10 days. The surface temperature can range from about 72.1°C to 416°C.
Could complex life develop here? I was thinking of some kind of fish that can burrow deep underground and emerge during the wet season.
