katch wreck`Unique phenomena are important in history but are difficult to study because they resist categorization and are therefore unpredictable. To examine the timing and circumstances of unique evolutionary events, we identified traits that evolved only once in the highly diverse phylum Mollusca as well as unique first occurrences of traits that evolved repeatedly since.`
Resolviendo la incógnita 🌐El calamar pigmeo sureño (Xipholeptos notoides) es el más pequeñoque se conoce. El manto de las hembras alcanza 25 mm de longitud, mientras en los machos solo llega a 15,8 mm. Por su tamaño, se oculta en pradera marina de la costa, cazando a pequeños crustáceos por la noche.📷Glen Whisson #calamares #squid #mollusca
