The venomous remipede is a small, blind crustacean that swims through underground water. It lives in flooded caves and cenotes on the Yucatán Peninsula, near the Caribbean Sea. It is special because it is one of the very few crustaceans known to use venom to catch its food.1

Leef in

Yucatán Peninsula and the Caribbean Sea, Mexico1

Atlantiese Oseaan, Karibiese See, Golf van Meksiko

Tuis

It lives in anchialine caves and cenotes close to the sea, where salty seawater lies beneath fresh water. The water grades smoothly from fresh to salt, a zone called a halocline.1

Lengte

2,5 cm tot 3 cm (1 in tot 1,2 in)1

Topspoed

omtrent 0,02 km/h (0,01 mph)

Swem, rowwe skatting

Wat eet dit?

It feeds on other crustaceans. It injects venom with its front claws, which liquefies the body contents of its prey.1

Hoe om dit te herken

It is blind and has no eyes or pigment, so it is pale.1
It has a long, slender, segmented body about 2.5 to 3 cm long.1
It has many legs, which it uses as oars to swim.1
Its front claws look like hypodermic needles.1
The number of body segments increases as it gets older. The highest number recorded was 36.1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

Its venom is similar to that of rattlesnakes and contains digestive enzymes and a paralysing toxin. The enzymes break down the body of its prey, and the toxin paralyses the prey. The venom is made in glands in the centre of the body and stored in reservoirs attached to the claws.1

As dit byt

Sit die wond in warm water, so warm as wat die persoon kan verdra sonder om te brand, en kry mediese hulp om die stekels te verwyder. Moenie self daarna grawe nie.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

Venom was believed to be completely absent from the roughly 70,000 known crustacean species until this animal was discovered.1

In 2007, researchers noticed its front claws looked like hypodermic needles. Venom reservoirs were later found attached to them.1

Its feeding technique is unique among crustaceans.1

It is hermaphroditic, meaning each individual has both male and female reproductive organs.1

It is one of 24 species in the class Remipedia. All of them live in caves, and they are found in the Caribbean, the Canary Islands and Western Australia.1

Remipede distribution is linked to the ancient Tethys Sea.1

Mite-breker

Mite: Crustaceans cannot have venom.

Waarheid: This remipede injects venom through its front claws, and this was the first crustacean found to do so.1
