Worldwide there are 356 turtle species on all continents except for Antarctica.
The United States has more species than any other country with about 62 currently recognized.
Mexico is in second place with 49 species, making North America a global hotspot for turtle biodiversity, especially in the southeastern United States.
Tortoises are bioengineers, keeping the landscape healthy and varied by dispersing seeds.
Turtles are great scavengers because they eat dead fish from lakes and rivers. They do no harm and they do a lot of good. Even when they are eating native water plants.
Between 2004 and 2014, desert tortoise populations in California, Nevada, and southern Utah declined 37 percent.
Unfortunately, these reptiles are now the most imperiled major group of vertebrates (animals with backbones) with about 60% of the 356 turtles species of modern turtles already extinct or threatened.
These animals are wild caught for meat and the pet trade in huge numbers. Add climate change and habitat destruction and it makes you wonder about their tenure on the Earth.
A plant or animal becomes extinct when the last living individual of its species dies, causing it to vanish from the earth forever.
Gopher TortoisesGopher tortoises are protected by federal law under the Endangered Species Act (ESA)
Habitat destruction is a significant threat to gopher tortoises.
Threats to the gopher tortoise also include habitat fragmentation and degradation, predation, lack of regulatory mechanisms, and incompatible use of herbicides in forest management and some silvicultural activities.
Gopher tortoises need large parcels of undeveloped land not fragmented by roads, buildings, parking lots, and other structures. Such barriers in natural habitat limit food availability and burrow space for tortoises plus expose them to closer contact with humans and their vehicles.
Their burrows also provide refuge for about 360 other species throughout its range.
Some of those species include black pine snakes, gopher frogs, Florida mice, foxes, skunks, opossums, rabbits, quail, armadillos, burrowing owls, snakes, lizards, frogs, toads, and many invertebrates.
Gopher tortoises spread seeds of many plants in their droppings, filling another important role in the ecosystem.
Sea TurtlesTravel throughout the world’s oceans
Sea Turtles have existed for over 100 million years. Suddenly, however, they are struggling to survive.
Sea turtles, especially green sea turtles, are one of the very few animals to eat sea grass.
Like normal lawn grass,
Over the past decades, there has been a decline in seagrass beds. This decline may be linked to the lower numbers of sea turtles.
Seagrass beds are important because they provide breeding and developmental grounds for many species of fish, shellfish, and crustaceans. Without seagrass beds, many marine species humans harvest would be lost, as would the lower levels of the food chain.
Beaches and dune systems do not get very many nutrients during the year, so very little vegetation grows on the dunes and no vegetation grows on the beach itself.
This is because sand does not hold nutrients very well. Sea turtles use beaches,
Sea turtles lay over 150,000 lbs of eggs in the sand along a 20 mile stretch of beach on the east coast of Florida s. Not every nest will hatch, not every egg in a nest will hatch, and not all of the hatchlings in a nest will make it out of the nest.
Sea turtles and manatees act as grazing animals that cut the grass short and help maintain the health of the seagrass beds.
All the unhatched nests, eggs,
Dune vegetation is able to grow and become stronger with the presence of nutrients from turtle eggs. As the dune vegetation grows stronger and healthier, the health of the entire beach/dune ecosystem becomes better. Stronger vegetation and root systems help to hold the sand in the dunes and helps protect the beach from erosion.
In recent field research, Dr. Cynthia Froyd of Swansea University took samples of soils throughout the Galapagos. Dr. Froyd then tested them for the types of environments for the flora, fauna, and animal species that are present.
They found that prior to 500 years ago “dung-affiliated” fungi, suggesting a large, plant-eating organism dominated the area. Since there aren’t other options for living in the Galapagos wetlands, the only option was the tortoises.
Prior to the arrival of man, tortoises roamed freely across the islands but starting in the 16th century, their numbers declined from 250,000 to 14,000 by 1970, and 5 of the original 14 subspecies have gone extinct.
Wetlands began drying up, a change recorded by the soil samples.
About 500 years ago, the tortoise feces vanish, and at the same time, the plants change.
The freshwater wetlands that once populated large areas of the Galapagos dried and the plants supported by those wetlands began dying, disappearing, and even going extinct.
The plants which supported those wetlands relied on the tortoises in several ways, including fertilization and churning up the ground as they walked through. The tortoises were a keystone species; once they began dying, the entire ecosystem surrounding them died with them.
What is Extinction?The state or process of a species, family, or larger group being or becoming extinct.
We Adopt ~ Breed ~ Rescue ~ Transport ~ Rehabilitate
Crazy Critters Inc. is a Private Non-Profit, 501(c)3, Exotic Animal Rescue and Sanctuary. Our Wildlife Facility is located in Eustis, Florida. We provide permanent homes to over 200 animals including lizards, turtles, skinks, geckos, birds, and assorted wildlife. Crazy Critters Inc. was established to provide non-domestic, non-releasable animals with a safe and permanent home.
Mostly Tortoises and Turtles call Crazy Critters Inc. home. What makes us unique is that after adoption, Crazy Critters Inc. continues to share the lives of the pets on social media. Providing an additional continued connection. When an animal finds its way to Crazy Critters, it has found a forever home.
Everyone in our community benefits when donors put their funds together to help protect animals and our environment. And the fact that the animals can call this a forever home makes it that much better. Your monetary donations help provide veterinary care, food, and supplies to the animals in our care.
In keeping with our commitment to a quality life for the animals here at the sanctuary, we provide a diet created specifically for each animal’s needs, the best veterinary care, enrichment programs for the animals, and maintain their spacious, safe habitats.
