Length at first maturity / आकार / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 60.0 cm TL पुल्लिंग / अलिंग; (संदर्भ 82); अधिकतम प्रकाशित वज़न: 1.8 kg (संदर्भ 82); अधिकतम सूचित उम्र: 20 वर्षो (संदर्भ 99652)
The males are approximately 1/3 the size of the females (sexual dimorphism) (Ref. 83). Lives in shallow waters, with sandy or muddy bottoms (Ref. 76). Found in intertidal and offshore areas (Ref. 1131). The horseshoe crab feeds at night on polychaete worms such as Cerebratulus, Nereis, and Cistenides (Ref. 76, 77), small mollusks, and seaweed (algae) found in the sandy ocean bottom (Ref. 76). Food is picked up by the chelicerae and passed back to the bristle bases, where it is "chewed." The food is then moved forward to the mouth (Ref. 75). It digs its food from sediments, grasping the prey with its legs. The prey is moved to the gnathobases where it is crushed before being pushed forward toward the mouth (Ref. 77). A life span of about 20 to 40 years (Ref. 78). Its predators are loggerhead turtles, pufferfish, leopard sharks and sea gulls (Ref. 82).
Life cycle and mating behavior परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | Eggs | Fecundity | Larvae
They reproduce with the use of the first pair of the six, flap-like appendages on the underside of the abdomen acts as a cover for the genital pore. The egg or sperm are released through this pore during spawning (Ref. 75). These eggs are fertilized by sperm released by an attached male and by one or more satellite males that typically congregate around the nesting pair (Ref. 81). While nesting, females bury themselves in the sediment near the water's edge and lay a series of discrete egg clusters, each containing 2,000-20,000 eggs (Ref. 80).
