response: Not sure, but they do have a slow rate of reproduction that makes the threats worse.
original_response: Not quite, but they will be very soon. They have a very slow reproductive rate so it takes awile for new ones to be had.
history: Hey there!! How are ya? Neither here nor there. How do you feel about the manta ray, which belong to the "Manta" genus? Are there different kinds of manta rays? Yes, there is a larger species known as "M. birostris" while a smaller one is "M. alfredi". Okay so you know some about them. Great!! Have you ever seen one in the ocean before? I have not but a convention of migratory species of wild animals protects them in international waters, but they're less protected when close to shore. I didn't know that. Are the endangered then?
knowledge: Their slow reproductive rate exacerbates these threats.
