The return trip was delayed for a further 11 days when weather forced Beagle to shelter further up the coast at Pernambuco, where Darwin examined rocks for signs of elevation, noted "Mangroves like rank grass" and investigated marine invertebrates at various depths on the sandbar.
A viaxe de retorno foi atrasada outros 11 días porque o tempo forzou o Beagle a refuxiarse na costa de Pernambuco, onde Darwin examinou rochas buscando signos de elevación, e anotou os "mangleirais como herbas de rango" e investigou os invertebrados mariños en varias profundidades dos bancos de area.
