There are plenty of candidates. The deep-diving, plankton-feeding megamouth shark was discovered as recently as 1976 and is only known from 40 or so specimens. A group of species called “river sharks” seem pretty rare. Some have been described from just a single collected specimen. There are many deep sea sharks that have only been […]
It was another great weekend on the beach for my family and everyone had new and exciting Beach Chair Scientist questions. The best part about being a Beach Chair Scientist is clarifying misconceptions, so I am going to start with the question that seemed to garner the most discussion this weekend “What are jellyfish?”.
