Veterinarian Mark Lowe talks about the Florida manatee in this video segment from WILD TV. Lowe describes his fascination with manatees which are an endangered species. Manatees have been in existence for millions of years. They are peaceful animals. Each has its own personality. A large public education program helps people learn about the history of manatees and the dangers they face with the decreasing supplies of vegetation and clean water they need to survive. Humans must be aware of how we pollute their water and endanger their survival when we use motorized vehicles in waters where they live.
Science, nature, animals
The following Frame, Focus and Follow-up suggestions are best suited for elementary or middle school students using this video in an English language arts or science lesson. Be sure to modify the questions to meet your students' instructional needs.
What is Frame, Focus and Follow-up?
Frame (ELA) What is the difference between a fact and an opinion? When can it be difficult to tell the difference between a fact and an opinion?
Focus (ELA) Listen for facts and opinions about manatees. Also, listen for comments that are hard to distinguish as either facts or opinions.
Follow Up (ELA) How would you define a fact? How would you define an opinion? Why is it important for us as learners to be clear about what the differences are?
Frame (SCI) What does it mean when we say a species is endangered? What species do you know that are on the endangered species list?
Focus (SCI) What has caused manatees to be placed on the endangered species list?
Follow Up (SCI) Recently U.S. officials have considered demoting manatees from the endangered species list to the threatened list because advances have been made in their protection and population. They would still be protected from harassment, poaching and killing, though. This is good news for the manatee and for the world. Discuss the implications to the world when animals are threatened with endangerment and extinction. What are the implications, for example, if there were no more polar bears due to global warming?
DR. MARK T. LOWE: So are you ready to meet our manatees here at Homosassa?
WALI: Yeah, I’m ready to meet the manatees here of Homosassa.
DR MARK LOWE: This is Willoughby.
WALI: Hi Willoughby.
DR. MARK LOWE: This is – oh, I’ve got somebody behind me here – and this is our biggest girl. This is Rosie.
DR. MARK LOWE: It’s my day. I come in once a week and get in the water and give them their vitamins and then I can look at the animals and get an overview of their general health.
DR. MARK LOWE: I started working for veterinarians when I was about twelve, thirteen years old. And I’ve been a veterinarian for over twenty-six years.
DR. MARK LOWE: My first experience with manatees came in 1989 when I was called down to Homosassa to look at one of the manatees that had a little minor skin rash. I got in the water with her and was able to touch the animal and feel the warmth of her body. Then, you could start to see some of the personality, some of the things that they did and it was just, just fascinating. And it was like something just flipped a switch in me and told me that I had to do everything that I could do possibly to help them. And if you get a chance to look in their eye, there’s somebody in there.
DR. MARK LOWE: Each one of them has their own personalities.
One of the biggest problems in Florida here, is getting hit by boats. We have Amanda here who has some scars down her side.
WALI: Oh man, look at that!
DR. MARK LOWE: So we have a large public education program going on to try and educate the public.
DR. MARK LOWE: The animals in the order sirena are the only aquatic herbivores meaning they spend their life in water and only eat plants like dolphins and whales tend to eat you know fish and that type of thing. They eat all the sea grasses and the various aquatic vegetation and fresh water.
WALI: They don’t eat any meat at all?
DR. MARK LOWE: No. In the wild, manatees tend to graze on the average of up to 8 to 10 hours a day. Historically, they don’t think there have been really large number of manatees in Florida. But we did notice that during the 1960’s and 70’s we did notice that the manatee population look like it was declining, so they were one of the first animals to be put on the endangered species list.
DR. MARK LOWE: And the biggest problem that we have is you and I coming to Florida, building a nice home on the waterfront, and taking away a lot of vegetation, putting fertilizers on our lawns, that are running into the water and degrading the water quality so they don’t have as much plant growth.
WALI: Oh wow.
DR. MARK LOWE: At one time about 60 to 80% of the grass beds in Tampa Bay were dead because of pollution. It is starting to come back, which is real good for the manatees. So it’s mainly, a human problem of us messing up their environment.
WALI: Wow, bubbles in the water. I’ve done that, but it’s a whole nother show.
DR. MARK LOWE: Manatees do produce a lot of gas. (Wali laughs)
WALI: What are we feeding them?
DR. MARK LOWE: This is actually elephant supplement is made by a feed company for elephants and manatee’s closest relative on land is the elephant.
WALI:Get out of here! I thought it was a seal but it’s an elephant.
WALI: Can they smell underwater?
DR. MARK LOWE: Not really smell but we think they have some chemo receptors that…
DR. MARK LOWE: …that they can taste like water and get different scents in water.
WALI: Is this Rosie?
DR. MARK LOWE: Ya, that’s Rosie.
WALI: Hi Rosie! Good seeing ya.
DR. MARK LOWE: She’s one of our oldest manatees and last time we weighed her about 5, 6 years ago, she was over twenty five hundred pounds.
WALI: How long do they live? Like what’s their average life span?
DR. MARK LOWE: We think 60 to 70 years probably. The oldest one that we have in captivity we actually know the age on is fifty three years old.
DR. MARK LOWE: Manatees have been around for millions of years. And there’s a message that they’re trying to tell me - that every time I look, it’s this message of at least I feel, is just of serenity. Slow down, smell the roses, and be peaceful.
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
