Habits

Sea turtles have a very mixed diet, with fish and cephalopods.

Animals, crustaceans, mollusks.

and seaweed. etc. for food. Feed on a variety of marine fish, shrimp, seaweed, crustaceans and molluscs in captivity, and eat a large amount, especially larvae, and prefer carnivorous bait.

Sea turtles eat aquatic plants while also swallowing seawater, ingesting large amounts of salt. In the tear ducts of the turtle.

Some special glands excrete these salts to keep the density of salt in and out of the body consistent, hence the "tearing" phenomenon of turtles on the shore. Healthy turtles raise their heads every once in a while to breathe; Place it on the floor, it will try to crawl; Pull its forelimbs and retract them vigorously; When the turtle is lifted, its forelimbs will slap up and down.

There are currently 5 species of sea turtles in our country.

There are only 7 species of sea turtles in the world, and there are 5 species distributed in China's waters, namely: leatherback turtles, Pacific ridley turtles, red turtles, green turtles and hawksbill turtles.

Sea turtles are very special marine creatures that live in the ocean almost all their lives, cruising in the warm waters of the world and returning to the beach only when it is time to lay eggs. Sea turtles are long-lived animals, many species can live more than 100 years, they are ectotherms like other reptiles, so they cannot live in cold waters, but leatherback turtles can maintain a certain constant temperature, body temperature can be higher than the water temperature of the surrounding seawater.

But today, threats such as entangled fishing nets, habitat degradation, poaching and marine litter put the survival of sea turtles in jeopardy.

World Turtle Day on May 23 is a festival for all turtles, whether tortoises, sea turtles or terrapids, to call for the protection of turtles and their habitats that have disappeared around the world.

Before World Turtle Day, we must protect sea turtles and do not buy, raise or eat species listed in National Key Conservation and CITES Appendices I and II, such as all species of tortoises, closed-shell turtles, sea turtles, etc. Then don't buy turtle products, such as hawksbill shell ornaments, etc. Finally, it is necessary to take good care of the ecological environment, reduce greenhouse gas emissions, do not litter, and do not release red-eared turtles (Brazilian turtles and snapping turtles) at will, so as not to exacerbate the invasion of invasive species to occupy the living space of native turtles.

Protecting sea turtles starts with you and me.

Sea turtle (scientific name: Chelonia spp.).) is a collective term for the sea turtles of the family Qijian and the family of leatherback turtles.

In order to adapt to aquatic life, the body is relatively flat, the limbs are fin-shaped, and the long forelimbs are like oars, which is very suitable for swimming freely in the water. With the exception of its head, limbs, and tail, it is covered in a hard shell. Sea turtles are mainly found in the waters of the Pacific, Atlantic and Indian Oceans.

Most sea turtles live in places such as shallower coastal waters, bays, corals, and estuaries, which flow into the sea. Except for laying eggs and basking in the sun, turtles usually rarely come ashore. The vast majority of turtles have a gentle temperament, and when they encounter an enemy, they will only shrink their heads and refrain from attacking them.

The lifespan of a sea turtle.

Most turtles have a lifespan of 120-200 years, but their lifespans vary depending on the species. The more common green turtles in China are mainly distributed in Guangdong, Zhejiang, Fujian, Taiwan, Shandong and other coastal areas, their life expectancy is shorter than other sea turtles, can only live about 100 years, in the current records, they live up to 152 years old. Most of the other species of sea turtles have a lifespan of between 100-200 years, of course, there are also longer lifespans, which can reach more than 200 years, but this is not common and is relatively rare.

Species of sea turtles

1. Leatherback turtles.

Leatherback turtles, also known as leather turtles, are mainly distributed in the Pacific Ocean, the Atlantic Ocean and the Indian Ocean, mostly inhabit the middle and upper layers of tropical seas, sometimes can enter the offshore and harbor bays, and occasionally also see in the temperate ocean, they are also the largest animals in the turtle order, the maximum body length can reach 3 meters, the turtle shell is more than 2 meters long, and the weight can reach 800-900 kilograms.

Leatherback turtles are very docile and feed mainly on jellyfish. Since jellyfish are not the best food for energy, the best way for leatherback turtles is to eat more jellyfish at once.

2. Loggerhead turtles. Loggerhead sea turtles, also known as red sea turtles, loggerhead sea turtles, are distributed in temperate and tropical Atlantic, Pacific Ocean, Indian Ocean and Mediterranean, mostly inhabit the continental shelf, often infested in coral reefs, and also enter bays, river hail mouths, saltwater lakes and other places, and are distributed in the South China Sea and East China Sea.

Loggerhead sea turtles prey mainly on benthic or floating crustaceans, molluscs, especially cephalopods, jellyfish and other invertebrates, and occasionally eat fish eggs and plant foods such as seaweed.
