Steller's sea cow is one of the most famous recently extinct species, on account of both it's huge size (said to grow to 7m) and the speed with which it was driven to extinction (c.27 years, 1741-1768).
Our goal is that local population of the Sirenia species are recovered, and the species diversity is maintained in order to increase resilience to the effects of climate change and major sto-chastic events, especially extreme weather.
local population of the sirenia species are recovered and the species diversity is main - tained in order to increase resilience to the effects of climate change and major sto - chastic events, especially extreme weather. Projected impact 2021–2025 (1) Increase knowledge about the different Sirenian species and populations across their ranges.
Aug 25, 2022 · While the living species of sea cows lack hindlimbs and are equipped with several anatomical adaptations that suit them to wholly aquatic lifeways, some of the earliest fossil sirenians were, by contrast, quadrupedal and amphibious.
The Protosirenidae (Eocene sirenians) and Prorastomidae (terrestrial sirenians) families are extinct. Sirenians are classified in the clade Paenungulata, alongside the elephants and the hyraxes, and evolved in the Eocene 50 million years ago (mya).
