When you visit a tidepool and put your finger into a sea anemone, it grabs onto your finger. What is really happening?

A. It shoots water out of its tissues, creating a vacuum that makes it feel like your finger is being pulled in.
B. A natural adhesive is deployed that feels sticky.
C. It activates stinging barbs that inject neurotoxin into your skin.
D. The tentacles are actually a suction device designed to grab onto any surface.
E. A series of tiny suction cups grab onto you.

When you put your finger into a sea anemone, the nematocysts on its tentacles are triggered, and they inject venom into your skin. This venom can cause irritation, pain, and sometimes allergic reactions in humans.

Explanation:

When you visit a tidepool and put your finger into a sea anemone, the sea anemone's tentacles come into contact with your finger. Sea anemones have specialized cells called cnidocytes on their tentacles, which contain stinging structures called nematocysts. These nematocysts act like tiny harpoons. When triggered by touch or chemical signals, the nematocysts release a harpoon-like structure that injects venom into their prey or potential threats.

So, when you put your finger into a sea anemone, the nematocysts on its tentacles are triggered, and they inject venom into your skin. This venom can cause irritation, pain, and sometimes allergic reactions in humans.
