The spawn (eggs) of a clownfish. The black spots are the developing eyes. Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, to spawn refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning. The vast majority of aquatic and ...
Early observations of Labidiaster starfish found that autotomized arms were swollen with mature eggs, suggesting that autotomy may be utilized for sexual propagation. Under this theory, starfish shed their arms in order to increase the range of egg dispersion and thus increase the possibility of eggs being fertilized by neighboring male ...
Asexual reproduction in starfish takes place by fission or through autotomy of arms. In fission, the central disc breaks into two pieces and each portion then regenerates the missing parts. In autotomy, an arm is shed with part of the central disc attached, which continues to live independently as a "comet", eventually growing a new set of arms.
Archaster typicus is a five-limbed star with long, slightly tapering arms with pointed tips. Occasionally three, four, or even six-armed individuals occur. Adults grow to 12 to 15 centimetres (4.7 to 5.9 in) in diameter, with males often being smaller than females.
The genus of this species has transitioned back and forth between Asterina and Patiria since its inclusion in Fisher's 1911 North Pacific Asteroidea monograph. [5] However, recent revisions based on molecular systematics have constrained Asterina and identified Patiria as a complex of three closely related species in the Pacific, including P. miniata, P. pectinifera in Asia and P. chilensis in ...
Clathrus archeri grows in 2 distinct stages, first an egg stage followed by the fungal "arms" emerging. During the egg stage, C. archeri forms a white ball-like egg shape, usually 2–3 cm (3 ⁄ 4 – 1 + 1 ⁄ 8 in) in diameter. [5] Next, the thallus emerges from the egg in a starfish-like shape with 4-6 arms on average (up to 8). [5]
In male seven-arm octopuses (Haliphron atlanticus), the hectocotylus develops in an inconspicuous sac in front of the right eye that gives the male the appearance of having only seven arms. In argonauts , the male transfers the spermatophores to the female by putting its hectocotylus into a cavity in the mantle of the female, called the pallial ...
