Jacques Cousteau, “The Silent World”, 1953 was the topic of an earlier blog post.
Tracy L. Lewis, “Cell Biology of Sponges”, 2011 also was the topic of an earlier blog post.
“Kitchen Sponge (poriferan) cell types” likewise was the topic of an earlier blog post.
Here I present: Jacques Cousteau (1910-1997), “The Silent World: A Story of Undersea Discovery and Adventure”, 1953, Part Two (2).
Jacques Cousteau pioneered the use of underwater camera; and, he earlier had invented the “Aqua-Lung” of SCUBA (self contained underwater breathing apparatus).
Captain Jacques Cousteau is about the same size as the “Barrel Sponge” shown at the TOP. Any of the 5,000 species of sponges (Barrel sponge, Kitchen sponge, Tube sponge…etcetera…) consists of 15 cell types.
These 15 cell types are constitute a unit of structure, shown BELOW.
A sponge is a water flow circuit; and in-flow hole (called “ostium”) & out-flow hole (called “osculum”) are anatomy terms used. The “holdfast” is the root-structure that anchors sponges to the sea floor. The “holdfast” is the bottom of a sponge; and, the “osculum” out-flow hole is the top of a sponge, shown ABOVE.
In the table ABOVE, item #10 is Porifera (sponge). As stated earlier , sponges have 15 cell types. The sponge is embryonically “monoblastic, asymmetric”. The table ABOVE, depicts “mammals” item #1.i Mammal (beef, pork, lamb, goat) at the top of the chart, having 211 cell types. Humans as mammals consist of 211 cell types; and, embryonically ”triploblaterian”.
Here I presented: Jacques Cousteau (1910-1997), “The Silent World: A Story of Undersea Discovery and Adventure”, 1953, Part Two (2). Captain Jacques Cousteau is shown in the photograph ABOVE.
Jacques Cousteau is famous for the big picture of the Ocean. Ocean is seventy-five (75%) percent of the Earth surface. The cartoon character “SpongeBob SquarePants” is popular because of the foundational role that sea sponge has in the Ecology. Jacques Cousteau (1910-1997), “The Silent World”, 1953 was fundamental to the beginning of the Environment movement.
“Just as there are four meats (beef, pork, lamb, goat); and four birds (chicken, turkey, duck, goose): there are four fish (salmon, tuna, cod, seabass). The table ABOVE is of the “food chain” showing “the four” foods from the perspective of Jacques Cousteau (1910–1997).
Abraham L. Kierszbaum & Laura L. Tres, “Histology & Cell Biology”, 2019 was the topic of an earlier blog post.
Bruce Alberts, Dennis Bray, Julian Lewis, Martin Raff, Keith Roberts, & James D. Watson, “Molecular Biology of the Cell”, 1994 was the topic of an earlier blog post.
