Moscardín

Ballena azul

El animal más grande que se conoce haya vivido en la Tierra; las ballenas azules pueden alcanzar 33 metros y 200 toneladas — sus corazones solos pesan tanto como un automóvil pequeño. Se encuentran en todos los océanos y migran entre las zonas de alimentación polares y las áreas de reproducción tropicales. Son filtradoras que consumen hasta 4 toneladas de kril al día. En peligro de extinción, con poblaciones globales estimadas entre 10.000 y 25.000 tras casi extinguirse por la caza de ballenas en el siglo XX.

Moscardín

<em>Eledone massyae</em>, the combed octopus, is a cephalopod mollusc in the family Octopodidae, assessed as Least Concern on the IUCN Red List. As a member of the genus <em>Eledone</em>, it is distinguished from true octopuses by possessing a single row of suckers on each arm rather than the double row characteristic of the genus <em>Octopus</em>. <em>E. massyae</em> is a benthic predator that uses its arms and suckers to capture and subdue prey, which typically includes crustaceans, fish, and other invertebrates. Like all cephalopods, it possesses a highly developed nervous system and sophisticated behaviors including the ability to change skin color and texture for camouflage. Specific habitat description and geographic range data are not available for this species in the current record. The organism does not maintain biological traits such as a fixed body length or mass across individuals in a consistent manner for reporting here.
