RPCScience 4Lesson 86-90

Hey guys today I will talk to you about the five amazing animals I learned about today. I learned bout the great white shark, the killer whale, the giant squid and last but not least the sperm whale. So let’s start with the GREAT WHITE SHARK!!!!!!!! Did you know that shark researchers actually tags and name the sharks that they find? Well yes they do and in fact the biggest one they ever found was taged and named deep blue and had a big bunch of bite marks on herself that are either from mating scars or combats with the other sharks. White sharks are responsible for the most attacks on humans. Their bite can be over 4,000 pounds of pressure. They can live up to 70 years and can swim 35 mph on a normal daily basis and they can go 10 times faster than the human swimmer when attacking (40 mph (miles per hour)). However the mako shark is the fastest shark of all of them. I think that sharks are very fascinating animals because their behaviour, their teeth and so much more like bite marks and mating scars and so much more!

Ok now let’s talk about the killer whale or the orca!

Orcas reach maturity at age 10. Wild orcas can live over 90 years old. Average lifespan is 50 years. Orcas often hunt together to overwhelm sharks and whales. They prevent small whales from resurfacing, causing them to drown.

Killer whales have high intelligence. This killer whale is playing with an ice chunk after a scientist threw a snow ball at it:

Ok on to the giant squid.

Giant squid move by sucking water into their mantles and squeezing it out (jet propulsion).

Giant squids have large eyes (11 inches in diameter) for detecting light in dark places.

The latest footage of the giant squid in action that was captured on camera was in 2015 but the latest footage on camera in the wild was in 2012. Colossal squid may be slightly larger than the giant squid, 46 feet long.

Ok on to the giant sperm whale!

The sperm whale the biggest predator in the ocean! Sperm whales hunt for giant squid. Sperm whales are known to dive over 6,000 ft. below the surface. They are the second deepest diving mammal. See the size of a sperm whale compared to a human:

They reach about 67 ft. in length.

Sperm whale compared to a blue whale the biggest mammal on earth:

That’s only the top five biggest whales but there plenty more species out there still and some that we haven’t even discovered yet!

Well that’s all folks, hope y’all enjoyed!
