许多度假者不知道是否有在加勒比海水母. And more importantly– 他们是危险的?
You’re contemplating a relaxing, fun-filled vacation to the Caribbean, where the waters are warm and the sun shines all day. But you’re not the only one who loves the Caribbean Sea. Millions of creatures call it home– and some are friendlier than others. Among the “non-amicable” ones are the dreaded jellyfish, who can leave you with the unwanted vacation souvenir of a painful stinging rash.
But have no fear! Your guide to jellyfish avoidance is here– and as long as you take some precautions, these strange gooey creatures won’t ruin your 加勒比海度假.
Jellyfish in the Caribbean
是, 有水母在加勒比地区. 事实上, there are many different species of them in Caribbean waters. 然而, the good news is that not all types of jellyfish sting! Most are completely harmless.
另一方面, there are a handful of jellies in the Caribbean that can cause rashes and other problems if they come into contact with humans. Here are common Caribbean jellyfish that you should watch out for:
1. Moon jellyfish
This jellyfish is pretty benign compared the others, but it can still leave your skin feeling itchy. These end up in the Caribbean during the warm months of the year, pushed there by ocean currents. They can live in both shallow coastal waters and in the open sea. Dome shaped and mostly transparent, they provide food for sea turtles. Note that the tentacles sting, and not the dome. You can actually move a moon jellyfish away by applying the palm of your hand to the top of its domed body.
Since these jellies look very similar to plastic bags, many sea turtles end up ingesting bags by mistake. If you happen to see a plastic bag floating in the ocean, remove it! Doing so will probably save a turtle’s life.
2. The Sea Wasp
海黄蜂, 也被称为框水母, are known as the most dangerous kinds of jellies that inhabit the加勒比海. 然而, 他们的毒药不是几乎一样的致死作为一个物种 (Chironex fleckeri) 的框水母发现，只有在太平洋地区. They are a bit tricky to see, since they are mostly transparent and float about 6 inches beneath the water’s surface. These creatures have a cube-shaped bell and 4 long tentacles. They are more prevalent during certain times of the year than others, depending on their spawning cycles. 平时, blooms ( sudden increases in population due to reproduction) occur about 10 days after a full moon.
蜇从海上蜂可能会导致恶心, 背痛, 和肢抽筋, 除其他症状. 如果刺痛了, 你应该让区域在热水和寻求医疗照顾，立即.
3. Portuguese Man ‘O war
This creature delivers a rarely fatal but extremely painful sting. 然而, it is easy to spot because its bluish-purple “sail” usually stays above the water’s surface as it swims. Its tentacles are extremely long, having been known to grow to up to 30′ 在长. Detached tentacles and even dead, washed up specimens can still sting.
技术上, the portuguese man o’war isn’t a jellyfish. 它是一个 siphonophore, which means it is a colonial organism made up of individual polyps that function together as if they were one animal. 然而, its appearance and similarities to jellyfish cause it to be classified as one by society at large.
Man o’war sightings are uncommon at Caribbean beaches. When they do end up near swimming zones, town authorities will usually close the beach.
Jellyfish are slightly more common in Caribbean waters during the warmer months. This is because the trade winds direct them toward the islands from March to June. 此外, these creatures prefer warmer waters. By the end of November, very few of them are left, thanks to cooler water temperatures.
Does the presence of jellyfish in Caribbean mean that you should cancel your vacation? By no means! There are truly no “deadly” jellyfish in the Caribbean. They are slow swimmers and do not attack humans. Jellyfish stings generally only occur when someone has bumped into one accidentally. 此外, taking a few simple precautions can greatly reduce your risk of encountering one.
- If you don’t know what it is, DON’T TOUCH IT.
- Wear water shoes when exploring sandbars.
- Don’t swim with open wounds.
- Don’t wear flashy, shiny jewelry or clothing. Jellyfish can mistake these for lures.
- Avoid swimming at night.
- Avoid floating seaweed, as jellyfish may be hiding there.
- Wear lycra or a protective suit when diving or snorkeling, or a t-shirt at the very least.
- Never touch a dead jellyfish. Its tentacles most likely still contain venom.
- Heed warnings about jellyfish “blooms” and sightings on beaches.
- Use protective anti-jellyfish sting lotions.
What to do when stung by a jellyfish
首先, do not panic. Most jellyfish stings are not medical emergencies. 然而, this does not mean that you should not seek medical advice from your doctor. If you or your child has trouble breathing or swallowing or shows other signs of an allergic reaction, call emergency services immediately. Seek medical attention if severe pain lasts for more than two hours, a rash remains for more than two weeks, or blisters appear. 除此以外, the following home remedies can help:
- Do NOT touch the area with your bare hands.
- If some stingers still remain lodged in the skin, use tweezers to remove them.
- Rinse the area with water (some doctors recommend hot water for this).
- Use over-the-counter anti-itch cream to reduce itching.
- Most doctors do NOT recommend treating jellyfish stings with meat tenderizer, urine, alcohol, or ammonia.
Note that treatment depends on the type of jellyfish sting. Always seek medical help immediately if the sting covers more than half of an arm or leg, or when there are signs of an allergic reaction.
