Yes yes, very nice, but the Giant Squid is more impressive.

The Giant Squid (Architeuthis) is one of the largest squids (and invertebrate, animal without a backbone). It swims the oceans at great depths. No one has ever seen a living Giant Squid. Only dead examples have been found.

These soft-bodied cephalopods are fast-moving carnivores that catch prey with their tentacles, then poison it with a bite from beak-like jaws. They move by squirting water from the mantle through the siphon, a type of jet propulsion. The Giant Squid's only enemy is the sperm whale, who hunts it deep in the ocean.

Anatomy: The largest-known Architeuthis was 57 feet (17.5 m) long. They have eight arms, two longer feeding tentacles, a beak, a large head, and two eyes, each the size of a basketball. They breathe using gills.

Diet: Giant squid are fast-moving carnivores (meat-eaters) that catch prey (probably large marine creatures) with their two feeding tentacles, then hold the prey with the eight arms and bite it into small pieces using a parrot-like beak. The esophagus runs through the brain, so the food must be in small pieces before swallowing.

Castoreum

Animal scent markings are notorious for smelling terrible. But castoreum is different. It has a musky smell that some people describe as van...
