In Greek Mythology, the Sirens (Greek singular: Σειρήν Seirēn; Greek plural: Σειρῆνες Seirēnes) are dangerous predatory creatures who lured men using their enchanting voices to shipwreck on rocks near their meadow island. Bristol Cove was once home to mermaids. Over a hundred years ago, a Siren enchanted the men of Bristol Cove.

2001年10月11日 · Here I describe Eocene fossils from Jamaica that represent nearly the entire skeleton of a new genus and species of sirenian—the most primitive for which extensive postcranial remains are known.

Sirenids are dwarf (Pseudobranchus, two species) or giant (Siren, two species) paedomorphic, perennibranchiate, fully aquatic salamanders that are elongate and lack hindlimbs entirely. They possess a fundamentally larval skull and hyobranchial configuration, which are unusual in many respects (Reilly and Altig, 1996).

Sirens are half human, half bird. I don't know how they are included in this specific marine family and not an avian one, but oh well. They don't have tails, but they are very beautiful and have great singing voices.

2015年4月16日 · Sirens were creatures from Greek mythology that enticed sailors to their destruction with their irresistibly beautiful singing. The most famous appearance of sirens in literature is in Homer's Odyssey where the hero Odysseus, on his long voyage home following the Trojan War, successfully escapes their enchanting call. In art, sirens usually ...

2023年3月30日 · To resolve outstanding questions concerning the phylogeny of Siren, we collected sequence and morphometric data from specimens across the range of Siren. We found S. lacertina and S. reticulata to represent strongly supported monophyletic groups, with S. reticulata having a sister relationship to all other Siren.

2023年4月11日 · Long, eel-like salamanders with external gills and only two front legs, sirens inhabit a variety of freshwater habitats across the southeast. This group made the news several years ago when Graham et al. (2018) described the Reticulated of Leopard Siren (Siren reticulata) as a new species.

All sirens share a conspicuous basic characteristic: the absence of rear limbs. Another notable characteristic is the presence of external gills throughout life. Sirens are completely aquatic, rarely emerging from water unless absolutely necessary.

2024年1月22日 · Adult sirens are often 7 to 9 feet tall from the tip of their head to the top of their fin and weigh 180 to 270 pounds. The top half of a siren has many similarities with humans, including teeth, intelligence, ears, and arms. Sirens have a unique respiratory system that makes them stand out from most other organisms.
