I saw a horseshoe crab for the first time.

The horseshoe crab is a creature that has continued to live since ancient times.

He got a new helmet.

A blackfly landed on my arm and was sucking blood.

Tachypleus tridentatus is designated as an endangered species in Japan.

He put on his helmet and headed for the battlefield.

He was wearing a helmet like an ancient warrior.

I need to leave the house right now.

His words always resonate in my heart.

His kindness is so great that it's unable to put into words.
