Precocial birds can provide protein-rich eggs and thus their young hatch in the fledgling stage – able to protect themselves from predators and the females have less post-natal involvement. Altricial birds are less able to contribute nutrients in the pre-natal stage; their eggs are smaller and their young are still in need of much attention ...
Phytoplankton concentrations are maintained, and enriched Artemia nauplii and rotifers are fed to the cobia larvae for 3–7 days after they hatch. The larvae require rotifers for at least four days after hatching. [ 8 ]
The behavior of an amphibian hatchling, commonly referred to as a tadpole, is controlled by a few thousand neurons. [4] 99% of a Xenopus hatchling's first day after hatching is spent hanging from a thread of mucus secreted from near its mouth will eventually form; if it becomes detached from this thread, it will swim back and become reattached, usually within ten seconds.

The holds are topped by hatch covers, onto which more containers can be stacked. Many container ships have cargo cranes installed on them, and some have specialized systems for securing containers on board. The hull of a modern cargo ship is a complex arrangement of steel plates and strengthening beams.
According to Stuart McLean's friends and colleagues, Sam is the character who most resembles McLean himself. [2] Arthur is the family dog. He likes soft ice-cream and considers himself dominant to Dave (much to Dave's surprise) and steals socks and potatoes. He was once a sheep in a Christmas pageant. Arthur is considered a full family member.
The eggs hatch after about three weeks into highly active larvae that feed on other zooplankton. The larvae have little resemblance to the adults, with long dorsal and pelvic fins and extensible mouths. Larvae and juveniles have been observed drifting just below the surface.
Males will care for the eggs and protect them until they hatch. [10] They will chase off predators or other rival males that come to the nest. [10] Eggs hatch around five days after mating, and the nest slowly deteriorates over this time. [5] [10] After hatching, males leave and will not use the same nest again. [5]
The hen alone incubates the eggs for 22 to 24 days before they hatch. The precocial downy chicks are then led by the female to the nearest body of water, where they feed on dead insects on the water surface. The chicks fledge in 46 to 47 days after hatching, but stay with the female until she has completed moulting. [12]
