In Other Nests | Macken Murphy

A natural history of infidelity and a history of science on the topic. Listen and learn about the oldest known laws in history, fish that get pessismistic without their boyfriend, the costs of monogamy, the ovulatory shift hypothesis (and a conspiracy theory about it), the mate-switching vs. dual-mating debate, and so much more.

Sunfish

Why do sunfish sunbathe? Will a sunfish squash my child? Can I use a dead sunfish to pay my taxes? Is that a baby whale? Come learn about the egg-laying champion on this episode of Species. Bibliography: https://docs.google.com/document/d/1Z5YnjyOkKs_kpttWcgSJkHKWKvNW56E9GSZFIxdzoRo/edit?usp=sharing Addendum: Some Japanese biologists believe that a new species of Mola should be acknowledged, named Mola alexandrini (bump-head sunfish). They have noticeable genetic and phenotypic differences from other Mola mola, with whom they are usually grouped. If Mola alexandrini is indeed a different species to Mola mola, then the bump-head sunfish (not the ocean sunfish) holds the title of largest sunfish specimen ever found.
