The 32 billion base pair long sequence of the axolotl's genome was published in 2018 and was the largest animal genome completed at the time. It revealed species-specific genetic pathways that may be responsible for limb regeneration. [35]
Lichens can grow on the shells of these slow-moving animals. [85] Tortoises keep a characteristic scute (shell segment) pattern on their shells throughout life, though the annual growth bands are not useful for determining age because the outer layers are worn off with time. A tortoise can withdraw its head, neck, and fore limbs into its shell ...
While most species require the central body to be intact in order to regenerate arms, a few tropical species can grow an entirely new starfish from just a portion of a severed limb. [2] Starfish regeneration across species follows a common three-phase model and can take up to a year or longer to complete. [2]

Four classes of arthropods each provide multiple examples, including sea spiders (with 4 to 6 leg pairs, [11] providing two examples) and pauropods (adults with 8 to 11 leg pairs, [12] providing four examples), but most of the examples listed are either millipedes (adults with 11 to 653 leg pairs) [5] [1] or centipedes (adults with 15 to 191 ...
Sloths are victims of animal trafficking where they are sold as pets. However, they generally make very poor pets, as they have such a specialized ecology. [64] The Sloth Institute Costa Rica is known for caring, rehabilitating and releasing sloths back into the wild. [65] Also in Costa Rica, the Aviarios Sloth Sanctuary cares for sloths.
