The mangrove horseshoe crab is a sea creature with a hard shell and a long spiky tail. It lives in warm, shallow, muddy coastal waters in South and Southeast Asia. Its flesh contains a deadly poison, so it is important to know it apart from a safe relative.1

Nakalalason o makamandag? Ang mga makamandag na hayop ay nag-iiniksiyon ng kamandag sa pamamagitan ng kagat o tusok. Ang mga nakalalasong hayop ay nakapipinsala kapag hinawakan o kinain. Ang isang ito ay nakalalason.

Ano ang kinakain nito?
It is a selective feeder on the bottom, eating mainly insect larvae, small fish, small crabs and thin-shelled bivalves. It has no jaws, so it grinds food with bristles on its legs and passes it to its mouth with its small front pincers.1

Paano ito makikilala

  • It is the smallest of the four living horseshoe crab species.1
  • Its tail has a rounded cross section. In the other species the tail is essentially triangular.1
  • Females are larger than males. Females are typically about 30.5 to 31.5 cm long including the tail.1
  • Adults have a large dome-shaped front shell, a smaller rear shell with spines on its edge, and a spike-like tail.1

Madalas mapagkamalang: It is often confused with Tachypleus gigas, which is harmless to eat. The mangrove horseshoe crab has a rounded tail, while T. gigas has a triangular one. Tachypleus tridentatus can live in the same habitat.1

Lakas ng lason

Nakalalason kapag kinain

Nakapipinsala lang ito kung may kumain dito.

Ano ang epekto ng lason nito?

Its flesh contains tetrodotoxin (TTX), a poison that is lethal. This is a poison in the food, not a venom from a bite or sting.1

Gaano ito kapanganib sa tao?

Panganib sa tao: NapakapanganibKaya nitong pumatay ng taong hindi nagamot.

  • Kung nahawakan o nakain mo ito: huwag kuskusin ang mata o bibig mo, hugasan ang mga kamay mo at kumuha ng tulong medikal.

Hindi ka nito hinahabol. Ang lason nito ay para lang walang kumain dito. Higit pa tungkol sa pag-iingat

Juveniles grow about 33% bigger each time they moult, taking about five moults to grow from 2 cm to adult size.1
