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

Ekhaya

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

Sitya ntoni?

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

Indlela yokusiqaphela

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

Amandla etyhefu yokuluma nokuhlaba

Ukuluma

Ityhefu iphuma ngamazinyo aso etyhefu okanye ngamazinyo aso xa siluma.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

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

Ukuba siyaluma

Faka inxeba emanzini ashushu, ashushu kangangoko umntu angakwazi ukunyamezela ngaphandle kokutshiswa, kwaye ufumane uncedo lwezonyango ukuze kususwe amava. Musa ukuwemba ngokwakho.

Soloko utsalela inombolo kaxakeka kuqala (112, 000, 911). Esi sisikhokelo soncedo lokuqala ngokubanzi, asilocebiso lwezonyango. Iziseko zoncedo lokuqala

Hlala ukhuselekile

Ungaze uchukumise, ubambe okanye uqhule isilwanyana sasendle, nokuba sincinci, kwaye nokuba sibonakala silele okanye sifile.
Sinike indawo. Ukuba udibana naso, hlala uzolile, buyela umva kancinci kwaye usiyeke sihambe ngendlela yaso.
Ukuba siyakuluma: hlala uzolile, musa ukushukuma, tsalela inombolo kaxakeka (112, 000, 911) okanye uye esibhedlele ngokukhawuleza. Khumbula ukuba sasikhangeleka njani, ifoto iyanceda.

Asikuzingeli. Sisebenzisa ityhefu yaso ukubamba ukutya okanye ukuzikhusela, kwaye singakhetha ukuzimela. Okungakumbi malunga nokuhlala ukhuselekile

Iinyaniso

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

Umqhekezi weentsomi

Intsomi: Crustaceans cannot have venom.

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