Blue blubber jellyfish

Catostylus mosaicus

只是會痛不要碰會痛，但不會對你造成嚴重傷害。

會螫人的觸手吃：肉

The blue blubber jellyfish is a large, rounded jellyfish that lives along the coast of Eastern Australia. It is blue to purple and pulses slowly as it swims. Its arms carry stings, and it can form huge blooms in estuaries and shallow bays.1

It lives in estuaries, semi-enclosed lagoons and shallow bays, and mostly in the saltier parts of estuaries. It can form large, dense blooms, which can interrupt people's use of beaches and coastal waters.1

長度

25 cm 到 30 cm (9,8 in 到 1 ft)1

最高速度

大約 0,9 km/h（0,56 mph）

牠吃什麼？

It feeds mainly on zooplankton (tiny animals drifting in the water), especially mollusc veligers, copepods and their nauplii. It uses stinging cells on its arms to immobilise prey.1

怎麼認出牠

Colour ranges from light blue to dark blue or purple.1
Large, rounded bell, about 25 to 30 cm across.1
The bell pulses in a rapid, staccato rhythm.1
Found along the Eastern Australian coast, often in large numbers.1

常被誤認為： Two forms are recognised on the Eastern Australian coast. Catostylus mosaicus mosaicus, found in New South Wales and southern Queensland, has small or no papillae (small projections) and a larger bell. Catostylus mosaicus conservitus, found in the Bass Strait, has clear papillae, is blue or white, and has a smaller bell.1

毒液力量

會螫人的觸手

有東西碰到時，成千上萬個小小的刺細胞就會發射。

牠的毒液有什麼作用？

Its arms carry stinging cells and can produce a mild but irritating sting. The sting is described as mild, and no further effects on the body are described.1

牠對人有多危險？

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

Its sting is described as mild but irritating. The main problem is the large blooms, which can interrupt recreation in coastal areas.1

牠害怕時會做什麼？

Its stinging cells on the arms are used to defend it from threats.1

如果牠螫人

離開水裡，把觸手拿掉（戴手套或用布）。
熱帶箱形水母：在螫傷處倒醋至少 30 秒，求救，並準備好做心肺復甦術（CPR）。藍瓶水母和大多數其他水母：用海水沖洗，再用熱水止痛。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠螫了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

小知識

Its stinging venom is being studied for possible anticancer effects against lung cancer cells in laboratory research.1

It is harvested for food and is considered a delicacy in some countries, including China and Japan.1

A small copepod lives on its oral arms and is thought to feed on mucus the jellyfish produces.1

Blooms can be very dense, and they can take food away from other animals such as fish.1

Sea turtles and jellyfish-eating fish, including tuna, butterfish, sunfish and spiny dogfish, prey on it.1

It has a partnership with photosynthetic algae, though it has less of these algae than many other jellyfish.1

排序: Rhizostomeae
各大洲: 印度洋, 太平洋, 珊瑚海, 海洋
寶寶: Fertilised eggs develop into free-swimming planula larvae, which settle on the seabed and grow into a polyp stage. The polyp then produces young jellyfish (ephyrae), which mature into the free-swimming medusa.1
