SPECIMEN // EUTH_01
🐾 Mammals: Eutheria (Placentals)
Sister Clade: Cows (Euungulata)
Blue Whale
Balaenoptera musculusDiagnostic Trait: Enormous streamlined body, dorsal blowhole, baleen plates replacing teeth, vestigial pelvic bones.
Whales are Cetaceans, which genetic and fossil evidence proved are nested deeply inside Cetartiodactyla (even-toed ungulates). Their sister taxon is the hippopotamus.
Deep Sky Observatory // Galaxy of the Day
M51 • NGC 5194
🌀 Unbarred Spiral Galaxy (SA)
Hubble Type: SA(s)bc pec
Whirlpool Galaxy
Canes Venatici • 31 million light-yearsDiagnostic Structure: Tightly wound two-arm grand-design spiral structure amplified by companion NGC 5195
M51 is the archetype of a grand-design unbarred spiral galaxy (`SA(s)bc`). Its sweeping logarithmic spiral arms are density waves compressed by the recent gravitational flyby of dwarf galaxy NGC 5195.
