Sengatan

Bisa keluar melalui penyengat.

Apa kesan bisanya?

It does not make its own venom. It takes the stinging cells (nematocysts) from the Portuguese man o' war and stores them in its cerata, a process called kleptocnidy. Because it concentrates this venom, its sting can be stronger than that of the animal it eats. Symptoms can include pain, nausea, vomiting, a rash, redness and blisters.1

Berapa bahaya ia kepada manusia?

Bahaya kepada manusia: MenyakitkanIa boleh jadi sangat sakit, tetapi hampir tidak pernah serius.

Picking up the animal can cause a very painful sting that may be potentially dangerous. Its sting produces symptoms similar to those of the Portuguese man o' war.1

Apa yang ia buat apabila takut?

It stores stinging cells from its prey in its cerata and uses them against predators.1

berguna untuk diketahui

Fakta

It can eat the Portuguese man o' war without harm, because it is immune to that animal's stinging cells.1

It floats upside down because its gas-filled stomach sac sits on the wrong side of its body, so its foot becomes its upper surface.1

Its blue colour is thought to reflect harmful ultraviolet sunlight.1

Its countershading, with blue on top and silver-grey below, helps it hide from predators above and below.1

It can lay up to 55 egg strings per hour.1
