New Moon New Disease New Hero

The video discusses three major discoveries: a new moon orbiting Neptune, a new tick-borne disease called Heartland Disease, and a new species of hero shrew with a unique spine. Neptune's moon was found using archival Hubble images, and its name will relate to sea gods. Heartland Disease, spread by Lone Star ticks, was identified in Missouri and is not severe. The hero shrew, found in Congo, has a spine four times stronger than other vertebrates, and its evolutionary purpose remains unknown.

Describe the unique feature of the hero shrew and its significance.

What evolutionary purpose might the interlocking spine of the hero shrew serve?
