Dodecolopoda is a monotypic genus of sea spider (class Pycnogonida) in the family Colossendeidae. [1] The only species in this genus is Dodecolopoda mawsoni. [1] This species is notable as one of only two species of sea spider with six pairs of legs (instead of the usual four leg pairs) and the first such species to be discovered.
Sea spiders live in many different oceanic regions of the world, from Australia, New Zealand, and the Pacific coast of the United States, to the Mediterranean Sea and the Caribbean Sea, to the north and south poles. They are most common in shallow waters, but can be found as deep as 7,000 metres (23,000 ft), and live in both marine and ...
Most colossendeids can grow to giant sizes as adults, far larger than any other sea spiders. The largest sea spider, Colossendeis colossea, can reach a leg span of 70 cm, [4] whereas the subfamily Hedgpethiinae includes tiny species with leg span of less than 1 cm. [5] Like most sea spiders, colossendeids usually have four pairs of legs, except for three species, Decolopoda australis, D ...
Spiders also have several adaptations that distinguish them from other arachnids. All spiders are capable of producing silk of various types, which many species use to build webs to ensnare prey. Most spiders possess venom, which is injected into prey (or defensively, when the spider feels threatened) through the fangs of the chelicerae. Male ...
Most ballooning journeys end after just a few meters of travel, although depending on the spider's mass and posture, [16] a spider might be taken up into a jet stream. The trajectory further depends on the convection air currents and the drag of the silk and parachute to float and travel high up into the upper atmosphere. [17]
C. megalonyx has an anterior pair and a posterior pair of simple eye forms called ocelli. [12] The four ocelli sit on a cone-shaped mound called the ocular tubercle. [7] C. megalonyx can vary in colour but typically exhibits shades of orange, yellow, and cream. [13] Photograph of C. megalonyx sea spider on a rock.
Colossendeis is a genus of sea spider (class Pycnogonida) belonging to the family Colossendeidae. [1] These sea spiders are typically found in the deep sea. This genus includes the largest pycnogonids, with leg spans frequently ranging from 40 to 50 cm (16-20 in). [2] The largest sea spider, Colossendeis colossea, can reach a leg span of 70 cm ...
Sea spiders of the family Pycnogonidae are recognisable by their stubby legs, rough-surfaced exoskeleton and the significant reduction of cephalic appendages. Chelifores (feeding pincers) and palps (sensory limbs) as seen in most other sea spiders are completely absent after postlarval metamorphosis, instead they using only their proboscis to suck juices from their cnidarian prey.
