kaalule. Näiteks (Dermochelys coriacea) on suurim merikilpkonnaline, ta võib kasvada 1.2 -1.9m pikkuseks ja kaaluda 200 500 kg. Väikseimad isendid on aga (Lepidochelys kempii) ja (Lepidochelys olivacea), kes kasvavad 55 - 75 cm pikkuseks ja võivad kaaluda kuni 50kg. Käesolev referaat on Eesti Maaülikooli "Mereteaduse" kursuse raames valminud töö, mis tutvustab 250 liigi seast ühte spetsiifilist rühma, kelleks on Merikilpkonnad(superfamily Chelonioidea). Referaat võtab põgusalt ja konkreetselt kokku merikilpkonnade liigi kui terviku. Tutvustab nende iseloomulikke jooni, kirjeldab välimust, toitumist, ohustatust, sigimist ja poegimist. Referaadi käigus proovitakse selgusele jõuda, kui väärtuslik merikilpkonnade liik meie loodusele ikkagi on? 2. Merikilpkonna tunnused: 2.1 Kilprüü Merikilpkonnadel on voolujooneline ovaalne sarvkilbistega kaetud kilprüü. Kilprüü on
habitat on the planet that contains insect-pollinated flowering plants. Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source, and the latter primarily for protein and other nutrients. Most pollen is used as food for larvae. Bees have a long proboscis (a complex "tongue") that enables them to obtain the nectar from flowers. They have antennae almost universally made up of 13 segments in males and 12 in females, as is typical for the superfamily. Bees all have two pairs of wings, the hind pair being the smaller of the two; in a very few species, one sex or caste has relatively short wings that make flight difficult or impossible, but none is wingless. The best-known bee species is the European honey bee, which, as its name suggests, produces honey, as do a few other types of bee. Human management of this species is known as beekeeping or apiculture.
In Africa, Theraphosids are frequently referred to as "baboon spiders". Asian forms are known as "earth tigers" or "bird eating spiders". Australians refer to their species as "barking spiders", "whistling spiders", or "bird spiders". People in other parts of the world also apply the general name "mygales" to Theraphosid spiders.
