Ectotherm | Definition, Characteristics & Examples from Chapter 24 / Lesson 11 25K This lesson will cover the difference between endotherms vs ectotherms. It will show examples of ectothermic and endothermic animals and will discuss the techniques of thermoregulation these animals use. ...
The majority of skin microbiome studies have focussed on humans, companion and domestic animals, and amphibians. Fish and birds have received substantially less attention, and many existing studies are cultivation-based. Few studies have explored the skin microbiome of reptiles [1]. The aim of this...
Class- Cartilaginous fish (6) - skeleton made of cartilage - movable jaws - pair of Fins- Placoid scales - internal fertilization- Speed of the fish determines if the fish goes towards or away from the surface. Cartilaginous fish examples - sharks skates and rays Placoid scales small, tooth-...
Learn the names and characteristics of vertebrate animals. You will learn about the characteristics of Birds, Mammals, Fish, Amphibians and Reptiles. Included are many examples of each animal type! Lessons include a matching puzzle to identify the animal type with the individual animal characteristics...
The HoxD2 group, absent in osteichthyan species as explained above, consists only of cartilaginous fish members. In this maximum likelihood (ML) tree, the lamprey sequence is placed outside gnathostome sequences (Figure 2A), which is incompatible with the “post-2R cyclostome” scenario ...

Deep blue: birds; purple: freshwater fish; pink: frogs; orange: mammals; yellow: reptiles. See Supplementary Material S1 for scientific names. 3.3. Comparison with previous extinction risk estimates The likelihood of imminent extinction of 79% (50/63) of the taxa considered here had been ...
Linnaean taxonomic names and primary sequence lengths are shown to the right; groupings shown on the left: Placozoa, basal invertebrate outgroup; Echinodermata and Hemichordata, basal deuterostomes belonging to the Ambulacaria; Cnidaria, basal metazoan invertebrates including jellyfish and sea anemona...
One of the striking results of deBraga & Rieppel's study is the number of presumably convergent features the choristoderes share with placodonts. Some examples (all apomorphies of both groups) include (a) the transverse process of the pterygoid extends below the maxillary tooth row; (b) ...
