(true or false) whale sharks and manta rays are very large predators and are a danger to divers? (true or false) octopus always remain the color that they were when born? (true or false) the sex of baby turtles is determined by the temperature of the sand they incubate in? (true or false) some corals produce both sperm and eggs?

1. False

Whale sharks and manta rays can indeed be large, and they are predators, but they do not pose threat to divers. Both of these species, even though they do not look alike at all, are part of the shark family. While they are both in the predator category, they actually eat miniature organisms and very tiny fish in general, thus not being anywhere near as aggressive or dangerous for the divers as some of their shark relatives. The manta rays for example do not even have teeth to pose a significant threat, they have a poisonous sting on their tail but that is only used for defense, not attack.

2. False

The octopuses are definitely one of the weirdest and most interesting animals on the planet. They are highly intelligent, have even been noticed using tools, have three hearts, one central and eight other independent brains in their tentacles, and also have a beak. Like all of that is not weird enough, they also have the ability to change their color, and not just the color all over, but also to mimic certain patters. The change of color is used for both camouflage for attack and for defense and avoiding predators.

3. True

The turtles spend the majority of their lives in water, but they still use the land for nesting. They will come to the sandy beaches, dig a large hole, and fill the hole with hundreds of tiny eggs, and than cover them with send. The sex of the turtles that are developing in the eggs depends directly on the temperature of the sand, so it can literary be a situation where all of them will be female because of the temperature, or all of them to be male because of the same reason.

4. True

The corals are a weird bunch. They look like plants, but they are actually animals. They also look like one compact unit, but they are actually millions, or billions miniature animals that are collaborating and build colonies. They also are interesting in their reproduction, as all of the species are able to reproduce asexually, but there are some that are able to reproduce both asexually and sexually, depending on the circumstances.

yes you are doing it right great gob
